The distance of the image is 26.67 cm

The magnification is -1.67

The image is real

The image is inverted

The focal length of the concave mirror = 10 cm

The distance of the object from the concave mirror = 16 cm

                 1/p + 1/q = 1/f

where p is the distance of the object

          q is the distance of the image

          f is the focal length

                  1/q = 1/f - 1/p

                  1/q = (p - f)/fp

                    q = fp / (p - f)

                    q = 16 x 10 / ( 16 - 10)

                       = 160 / 6

                       = 26.67 cm

The distance of the image from the concave mirror is 26.67 cm

                  M = -q/p

where M is the magnification

                 M = -26.67 / 16

2. Total Distance = 750 m

Total Time = 8 min

Average speed = 93.75 m/min

3. 200 m/min to the east.

4. Acceleration

Explanation:

1.

Taking into account the description, we can graph the situation as follows:

2. Now, we can find the total distance and the total time traveled as follows:

Distance = 200 m + 100 m + 150 m + 200 m + 100 m

Distance = 750 m

Time = 3 min + 1 min + 1 min + 1 min + 1 min + (30 s + 30 s)

Time = 3 min + 1 min + 1 min + 1 min + 1 min + 1 min

Time = 8 min

Then, the average speed will be equal to:

Average Speed = Total Distance / Total time

Average speed = 750 m/ 8 min

Average speed = 93.75 m/min

3. The speed is calculated using the total distance traveled and the velocity is calculated using the displacement. It means that the velocity takes into account the direction of the movement, so the important points are only the initial and final position, to calculate the velocity, the path between the initial and final position doesn't matter.

Then, from point D to point E, we will find the velocity as follows:

So, the velocity from point D to E is 200 m/min to the east.

4. There is acceleration when there is a change in the velocity. Since from point E to F, you start with a specific velocity and then change the velocity (start to run), we can say that the motion is best described as acceleration.

The statement that is true about distance an displacement is that a person makes a round journey, finishing where they started. The displacement for the trip is 0, and the distance is some non-zero value.

Distance is used to measure the path that an individual travels. If an individual moves from a point a to b the distance is measured from the point a to b.

Displacement measures any deviation or shift from where an object/ individual originally exist or stays.

The total distance covered by an individual is usually more than displacement or at times equal to displacement.

Displacement can be less than the total distance or equal to distance.

For an individual who makes a circular journey and return to the original spot there is not deviation which makes the displacement zero but the distance will be measured and recorded.

Therefore,

The displacement for the trip is 0, and the distance is some non-zero value.

The number of cards Aaron had are 19 when Aaron, Bonny and Connor are playing a game with cards which are a total of 101.

Given that Aaron, Bonny and Connor are playing a game with cards.

Let the number of cards Aaron had = x

Bonny has twice the cards of Aaron = 2x

Number of cards Connor had are 6 more than Bonny = 2x + 6

The total number of cards = 101

Then by adding the number of cards that Aaron, Bonny and Connor had we get the total number of cards.

Then Aaron cards + Bonny cards + Connor cards = 101

x + 2x + 2x + 6 = 101

5x = 101 - 6 = 95

x = 95/5 = 19

Answer:

a = \(-\frac{25}{27}\) m/s²

Explanation:

Acceleration (a) = (final velocity - initial velocity) ÷ (final time - initial time) =  \(\frac{v_{f} - v_{i} }{t_{f} - t_{i} }\)

Converting the speed from km/h to m/s;

100 km = 100000m

1hr = 3600s

∴ 100km/hr ⇄ \(\frac{100000 m}{3600 s}\) = \(\frac{250}{9} m/s\)

Acceleration = \(\frac{0 - 250/9}{30}\) = \(-\frac{250}{9 * 30} = -\frac{25}{27}\) m/s²

A 1000 kg steel beam that is being supported by two ropes is a common example of a static equilibrium problem in physics.

When the beam is not moving, the net force acting on it must be zero, and the sum of the torques acting on it must also be zero. Since the beam is being supported by two ropes, the tension in each rope must be equal to half of the weight of the beam, which is 5000 N. This means that the total upward force acting on the beam is 10000 N, which is equal to the weight of the beam. To ensure that the beam remains in static equilibrium, the two ropes must be positioned such that the torques they produce are equal and opposite. The position and angle of the ropes can be calculated using the principles of torque and equilibrium.

The voltage across a capacitor that has been charged to a certain voltage and then connected to a resistor can be described by the following equation:

V = V0 * e^(-t / RC)

where V is the voltage across the capacitor at time t, V0 is the initial voltage across the capacitor, R is the resistance of the circuit, C is the capacitance of the capacitor, and e is the mathematical constant e (approximately equal to 2.71828).

Plugging in the given values, we get:

V = 150 V * e^(-6.20 ms / (8.00 μF * 470 Ω))

Note that we need to convert the capacitance from microfarads (μF) to farads (F) and the time from milliseconds (ms) to seconds (s) to ensure that the units are consistent in the equation.

V = 150 V * e^(-6.20e-3 s / (8.00e-6 F * 470 Ω))

= 150 V * e^(-1.484)

= 150 V * 0.2271

= 34.07 V

Therefore, the voltage across the resistor after 6.20 ms is approximately 34.07 V.

Explanation:

The intensity of sound is inversely proportional to the square of the distance from the source. The intensity of sound at 4 m away from the source is approximately \(0.993W/m^{2}\) (watts per square meter).

The intensity of sound is defined as the power per unit area. According to the inverse square law for sound propagation, the intensity of sound is inversely proportional to the square of the distance from the source. Mathematically, it can be expressed as

\(I=P/(4\pi r^{2})\)

where I is the intensity, P is the power, and r is the distance from the source.

Given that the power of sound at the source outlet is 100 W and the distance from the source is 4 m, we can substitute these values into the formula. Thus, we have

\(I = 100 W / (4\pi (4 m)^2)\)

Simplifying this expression, we find that the intensity of sound at 4 m away from the source is approximately \(0.993W/m^{2}\) (watts per square meter).

When a pulse traveling along a light spring reaches the boundary with a heavier spring, some of the pulse energy will be reflected back into the light spring, and some will be transmitted into the heavier spring. The amount of energy reflected and transmitted depends on the properties of the two springs and the angle of incidence of the pulse.

In general, if the two springs have different spring constants, the pulse will experience a change in velocity and amplitude at the boundary. The pulse will slow down when it enters the heavier spring, because the heavier spring will offer more resistance to deformation than the lighter spring. As a result, the wavelength of the pulse will decrease, and its amplitude will increase.

Whether the pulse is inverted or not at the boundary depends on the relative phase of the reflected and transmitted waves. If the boundary conditions are such that the reflected wave is in phase with the incident wave, the pulse will be inverted. If the reflected wave is out of phase with the incident wave, the pulse will not be inverted.

The exact behavior of the pulse at the boundary between the two springs depends on the specific properties of the springs, such as their spring constants and densities.

However, in general, the pulse will undergo a change in velocity, wavelength, and amplitude at the boundary, and may or may not be inverted depending on the relative phase of the reflected and transmitted waves.

The gravitational potential energy

gpe = mgh

\(\tt gpe=75\times 9.8\times880=646,800~J\)

To position two oppositely charged objects to give them the lowest potential energy (PE), they should be placed as close together as possible.

This is because the PE of a charged object is inversely proportional to the distance between the objects. As the distance between the objects decreases, the PE also decreases.

Therefore, to minimize the PE( potential energy ) between two oppositely charged objects, they should be positioned as close together as possible, without actually touching each other.

This configuration represents the state of maximum stability and minimum potential energy, as the attractive electrostatic forces between the objects are maximized when they are in close proximity.
