Student 1 is right. If we measure current through the battery, We can determine the resistance of the variable resistor.

How can we determine unknown resistance in this case?

Let, current through the battery is I

Now, equivalent resistance of the circuit is given by,

\(R= \frac{R_1*(R_2+R_{unknown})}{ R_1+R_2+R_{unknown}}Current through the battery is given by, I=\frac{E}{R}= \frac{E*(R_1+R_2+R_{unknown})}{R_1*(R_2+R_{unknown})}By, solving the above relation we can get, the value of the unknown resistance.\)

In series circuit, the resistance of all the components adds up. If the resistance of individual component is R₁, R₂, R₃,...

Equivalent resistance for a series circuit is

R = R₁ + R₂+ R₃ +...

From Ohm's Law,

The current in series circuit is I = V R where R is equivalent resistance, V is the net voltage.

Voltage drop across each component is V₁, V₂,V₃,..

V₁ = I R₁

V₂ = I R₂

V₃ = I R₃

I R = I R₁ + I R₂+ I R₃ +...

⇒ R = R₁ + R₂+ R₃ +...

Answer:

Explanation:

A decrease in the price level results in an increase in the quantity of real GDP demanded because a lower price level stimulates consumption, investment, and net exports.

When the price level decreases, it means that the general level of prices for goods and services in the economy has fallen. This can have several effects:

Consumption: With lower prices, consumers can purchase more goods and services for the same amount of money. This increase in purchasing power encourages higher levels of consumption, leading to an increase in the quantity of real GDP demanded.

Investment: Lower prices can also reduce the cost of production for businesses. This can incentivize firms to invest in new projects or expand their existing operations, as they can produce goods and services at a lower cost. Increased investment boosts economic activity and contributes to higher real GDP demand.

Net Exports: A decrease in the price level can make domestic goods and services relatively cheaper compared to foreign goods and services. This can lead to an increase in exports as foreign consumers find the goods more affordable. At the same time, it can discourage imports as domestic consumers may choose cheaper domestic alternatives. This increase in net exports contributes to an overall increase in the quantity of real GDP demanded.

We can presume that an ambulance with its siren activated is rushing to get somewhere and, depending on the driving circumstances, is likely travelling between 30 and 150 km/h. The vehicle's speed can be determined using the Doppler effect equation. Let va represent the ambulance's maximum speed. The frequency, f'=(vvv a)f=560Hz, is audible as it gets closer.

Because the source is travelling in the direction of the observer, a negative sign appears. The ambulance is described as moving away by the opposite sign with source velocity magnitude. The Doppler shifted frequency as it recedes is f')=(vv+v0)f=480Hz.

The speed of the source can be calculated as va=v(f'f')f'+f'=(343ms)(560Hz480Hz)560Hz+480Hz=26.4ms by solving the second of these equations for f and substituting into the other.

y = 10.5/15 g/cm3

ANS == 700kg/m3

The minimum sample period required is:

T = 1 / (2 x 1) = 1/2 ( we need to sample g(t) every 0.5 units of time or twice per unit of time)

When we sample a continuous-time signal, we need to ensure that we do not encounter aliasing, which occurs when the sampling rate is not sufficient to accurately represent the original signal.

To avoid aliasing in the function g(t) = sinc(2t), we need to sample it at a rate that is twice the maximum frequency present in the signal.

In this case, the maximum frequency is 1 Hz (half the bandwidth of the sinc function), so we need to sample it at 2 Hz.

Therefore, the sample period required to avoid aliasing is 1/2 = 0.5 seconds.

This means that we need to take a sample of the function every 0.5 seconds to ensure that we obtain an accurate representation of the original signal without aliasing.

To make a ray diagram for this problem, we can draw two rays from the top and bottom of the object, parallel to the principal axis and then reflecting off the mirror and converging at a point.

Another ray can be drawn from the top of the object through the focal point and then reflecting off the mirror parallel to the principal axis. This ray will also converge at the same point as the first two rays.

Using the mirror equation, we can find the image distance (di) as:

1/f = 1/do + 1/di

where f is the focal length of the concave mirror and do is the distance of the object from the mirror. Substituting the given values, we get:

1/15 = 1/10 + 1/di

Solving for di, we get:

di = -30 cm

The negative sign indicates that the image is virtual and upright.

Using the magnification equation:

m = -di/do

where m is the magnification. Substituting the given values, we get:

m = -(-30 cm) / 10 cm

m = 3

The positive magnification indicates that the image is upright compared to the object.

Finally, we can determine if the image is taller or shorter than the object by comparing their heights. Since the magnification is greater than 1, the image will be taller than the object. Therefore, the image is upright, virtual, and taller than the object.
In order to locate the image using a ray diagram and calculate the image distance, magnification, and determine the image properties, we will apply the mirror equation, magnification equation, and proper sign convention.

Mirror equation:
1/f = 1/u + 1/v
where f is the focal length, u is the object distance, and v is the image distance.

Given:
f = -15 cm (concave mirror has a negative focal length),
u = -10 cm (object distance is negative as per sign convention).

1/(-15) = 1/(-10) + 1/v
Solving for v, we get:
v ≈ -30 cm (image distance is negative, indicating a real image)

Magnification equation:
M = -v/u
M = -(-30)/(-10)
M = 3

The magnification is 3, indicating the image is taller than the object.

The image formed by the concave mirror in this case is real, inverted (since the magnification is negative), and 3 times taller than the object.

The image formed by the concave mirror is real, inverted, and shorter than the object. The image distance is 6.0 cm, and the magnification is 0.6.

The image formed by the concave mirror is real, inverted compared to the object, and shorter than the object.

To locate the image, we can use the ray diagram method. Drawing two rays will be sufficient:

1. Ray 1: Draw a ray parallel to the principal axis that passes through the focal point on the opposite side of the mirror. After reflection, this ray will appear to pass through the focal point on the same side of the mirror.

2. Ray 2: Draw a ray that passes through the center of curvature of the mirror. This ray will be reflected back along the same path.

The point where these two rays intersect after reflection gives the location of the image.

Using the mirror equation:

1/f = 1/v - 1/u

Where:

f = focal length of the mirror (15.0 cm)

v = image distance from the mirror

u = object distance from the mirror (-10.0 cm, considering the object is placed on the same side as the incident light)

Substituting the values:

1/15.0 = 1/v - 1/(-10.0)

Simplifying the equation:

1/v = 1/15.0 + 1/10.0

Calculating:

1/v = 2/30 + 3/30 = 5/30

Taking the reciprocal:

v = 30/5 = 6.0 cm

Using the magnification equation:

magnification (m) = -v/u

Substituting the values:

m = -(6.0 cm)/(-10.0 cm) = 0.6

Therefore, the image distance is 6.0 cm and the magnification is 0.6.

The image formed by the concave mirror is real because the image distance is positive (6.0 cm). It is inverted compared to the object because the magnification is negative (-0.6).

The image is shorter than the object because the magnification (0.6) is less than 1.

3a) The mass of water that goes over the falls every second is 1 x 10⁶ kg.

3b) The gravitational potential energy of 1 kg of water at the top of the falls 1000 J.

3c) The speed of the water as it reaches the bottom if all the GPE stored in 1 kg of water is transferred to kinetic energy is 44.72 m/s.

3d) The water will not be falling as fast as the speed calculated in part c suggests because of the presence of air resistance and the fact that the water falls through a medium (air) which offers resistance to its motion.

3e) The energy transferred when the GPE stored in the water falling in one second is transferred to other energy stores is finally stored in thermal energy stores due to the heat generated by the water as it hits the bottom.

1a) To calculate the amount of energy stored in the three weights, we use the formula given below:

E = mgh

Where,E = Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

For the 4.5 kg weight:

E = 4.5 x 10 x 0.7 = 31.5 J

For each of the 3.5 kg weight:

E = 3.5 x 10 x 0.7 = 24.5 J

Thus, the total energy stored when all three weights are raised by 70 cm is:

31.5 J + 24.5 J + 24.5 J = 80.5 J

1b) To calculate how far the 4.5 kg weight must be lifted to store 45 J of energy, we use the formula:

E = mghh = E/mg = 45 / (4.5 x 10) = 1 m2a)

To calculate the gravitational potential energy stored in the water in the tank when it is full, we use the formula given below:

E = mgh

Where,E = Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

The mass of 1 litre of water is 1 kg and the tank can hold 200 litres of water. Therefore, the total mass of water in the tank is:

Mass = 200 kg

The height of the tank is 2 m.

Therefore, the gravitational potential energy stored in the water in the tank is:

E = mgh = 200 x 10 x 2 = 4000 J

Assumptions made in the answer:

We have assumed that the tank is full.

2b) To calculate the speed at which the water would come out of the bathroom and kitchen taps, we use the formula given below:

PE = KEPE = mghKE = 1/2mv²

Where,PE = Potential Energy (Joules)

KE = Kinetic Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

v = Velocity (m/s)

Assuming that the potential energy of the water in the tank is converted into kinetic energy when the water flows out of the taps, the potential energy stored in the water in the tank is given by:

PE = mgh = 200 x 10 x 2 = 4000 J

The potential energy is converted into kinetic energy when the water flows out of the taps.

Therefore, KE = 1/2mv²v² = 2KE/mv² = 2(4000)/200 = 40 m²/s²v = √(40) = 6.32 m/s (speed of the water coming out of the taps)

3a) To calculate the mass of water that goes over the falls every second, we use the formula given below:

Mass = Volume x Density

Where,Volume = 1000 m³/s, Density = 1000 kg/m³, Mass = 1000 x 1000 = 1000000 kg = 1 x 10⁶ kg

3b) To calculate the gravitational potential energy of 1 kg of water at the top of the falls, we use the formula:

E = mgh

Where,m = 1 kg, g = 10 N/kg, h = 100 m, E = 1 x 10 x 100 = 1000 J

3c) To calculate the speed of the water as it reaches the bottom if all the GPE stored in 1 kg of water is transferred to kinetic energy, we use the formula given below:

PE = KEP

E = mgh

KE = 1/2mv²

Where,PE = Potential Energy (Joules)

KE = Kinetic Energy (Joules)

m = Mass (kg)

g = Gravity (10 N/kg)

h = Height (m)

v = Velocity (m/s)

Assuming that all the potential energy is converted into kinetic energy when the water reaches the bottom,

PE = KEKE = mghv² = 2mghv² = 2(1)(10)(100)v² = 2000v = √(2000) = 44.72 m/s

3d) The water will not be falling as fast as the speed calculated in part c suggests because of the presence of air resistance and the fact that the water falls through a medium (air) which offers resistance to its motion.

3e) To calculate the total energy transferred per second as the GPE stored in the water falling in one second is transferred to other energy stores, we use the formula given below:

Power = Energy / Time

Where,Power = 1 x 10⁶ x 10 x 100 = 1 x 10⁹ W = 1 GW (assuming that 1 m³ of water falls every second)3f)

Answer:The object will begin to move

Explanation:

The intense heat Jimmy felt when drifting close to the sun was primarily due to radiant heat transfer, as the sun's radiant energy reached him directly in the vacuum of space.

Radiant heat transfer occurs through electromagnetic waves, such as infrared radiation, which can travel through the vacuum of space. The sun emits an enormous amount of radiant energy, including visible light and a significant portion of infrared radiation. As Jimmy drifted closer to the sun, his proximity exposed him to a much higher intensity of radiant heat.

Unlike conduction or convection, which require a medium to transfer heat, radiant heat can travel through space without the need for a material medium. Consequently, even in the vacuum of space, the radiant energy emitted by the sun can reach Jimmy and warm his body directly.

This intense radiant heat transfer from the sun to Jimmy's body caused him to feel an unprecedented level of heat. The absence of a protective atmosphere or insulating medium amplified the effect of the sun's radiation, resulting in a scorching experience for the astronaut.

The mass of the student on the left side of the teeter totter is 43.68 kg

Since the teeter totter is in equilibrium, the sum of moments about its center of mass is zero. That is, the clockwise moment, M = anticlockwise moments, M'

Taking moments of the students weight about the center, we have

m₁gx₁ = m₂gx₂ where

m₁x₁ = m₂x₂

Given that their total mass is 78 kg, we have that m₁ + m₂ = 78.

So, m₂ = 78 - m₁

Substituting m₂ into the equation, we have

m₁x₁ = m₂x₂

m₁x₁ = (78 - m₁)x₂

Making m₁ subject of the formula, we have

m₁x₁ = 78x₂ - m₁x₂

m₁x₁ + m₁x₂ = 78x₂

m₁(x₁ + x₂) = 78x₂

m₁ = 78x₂/(x₁ + x₂)

Substituting the values of the variables into the equation, we have

m₁ = 78x₂/(x₁ + x₂)

m₁ = 78 × 1.4 m/(1.1 m + 1.4 m)

m₁ = 109.2 kgm/2.5 m

m₁ = 43.68 kg

Answer:

final velocity in km/h= 67.2km/h

Explanation:

Data

initial velocity (u)= 24km/h

from 36km/h = 10m/s

then 24km/h= u

hence,

\(u= \frac{24}{36} \times 10\)

u= 20/3 m/s

Time= 6s

Acceleration= 2m/s²

\(v = u + at\)

\(v = \frac{20}{3} + 2(6)\)

\(v = \frac{20}{3} + 12\)

\(v = \frac{56}{3} \)

final velocity = 56/3 m/s

From 10m/s=36km/h

56/3 m/s = V

V(km/h)=

\( \frac{56}{3} \times \frac{36}{10} \)

V(km/h)=67.2km/h
