The free body that shows the ball falling at terminal velocity is B. A free body diagram with 2 forces: the first pointing downward labeled F Subscript g Baseline 20 N and the second pointing upward labeled F Subscript air Baseline 20 N.

It should be noted that at terminal velocity, the ball will stop accelerating and the net force on the ball will be zero.

In this case, for the net force to be zero, equal, their resultant force is zero. That is F₁ + F₂ = 0 ⇒ F₁ = -F₂

Since F₁ = 20 N, then F₂ = -F₁ = -20 N

Therefore, if F₁ points upwards since it is positive, then F₂ points downwards since it is negative.

Therefore, the correct option is B.

An algorithm that calculates the time a train needs to arrive at a destination given speed and distance \(Time=\frac{Distance}{Speed}\).

The amount of the shift in approach per unit of time or the size of the displacement over time for an object can be used to describe speed, which would be a scalar quantity in everyday language and kinematics.

The maximum speed that can be maintained when a period grows closer to zero is the starting speed.

By dividing the object's distance traveled by the duration of the interval, the mean pace of the object for the given period is calculated. Speed and velocity are not always the same thing.

The algorithm to calculate the time required will be,

Let the distance covered by the train is D and the speed of the train be S.

Then, the time taken by the train will be,

T = D/S

Here, D is the distance and S is the speed.

Compared to the voltage V2 across the second capacitor (C2), the voltage V1 across the first capacitor (C1) will be lower thus option C is correct

In a series circuit with two capacitors (C1 and C2), the voltage is divided between the two capacitors based on their capacitance values. The capacitor with the larger capacitance will have a greater voltage drop across it than the capacitor with the smaller capacitance.

Therefore, the voltage V1 across the first capacitor (C1) will be less than the voltage V2 across the second capacitor (C2). Thus, the correct answer is C. V1 < V2.

Answer:

I would say the smaller object.

Explanation:

In any case, thermal energy can be spread throughout the object easier, and quicker, rather than the bigger object.

For example: You are boiling two pots of water, let's suppose Pot A has twice as much as Pot B:

|--------------------- |              |                            |

|                          |              |----------------------- |

|_____________|              |______________|

Pot A                                 Pot B

If you boil them at both the same time, temperature, and continue that for sometime, your results will be that Pot B will have risen in temperature alot faster than Pot A

The comparison:

In the seven years time, he saved 61320000p so the turbine costed 61320000p.

Cost of 1000 watt electricity = 35p

Cost of 1 watt electricity = 35/1000p

Cost of 1 watt electricity = 0.035p

Electric power rating of fridge = 35W

The power consumption of fridge in one hour = 35W

The power consumption of fridge in 24 hours,

= 24×35

= 840 watt

The power consumption in one year = Power consumption of 24hours × 365

The power consumption in one year = 850 × 365 W

= 306600W

Power consumed by fridge in 7 years = 7 × 306600

Power consumed by fridge in 7 years = 2146200 W

Cost of turbine is equal to the savings in 7 years,

Saving in 7 years = total power consumed/cost of one watt electrical power

Savings in 7 years = 2146200/0.035p

Savings in 7 years = 61320000p

The saving of seven years is equal to the cost of turbine, so the cost of the turbine is 61320000p.

The direction of the magnetic field at the center marked "x" is determined by the vector sum of the magnetic fields generated by each wire in the given configuration.

To determine the direction of the magnetic field at the center marked "x" in the given configuration, we can use the right-hand rule for magnetic fields.

Considering the current through the first straight wire is 1.5A, if we curl the fingers of our right hand in the direction of the current (from bottom to top), the thumb points in the direction of the magnetic field at that wire.

Now, focusing on the circular loop with a current of 2.0A, we can use the right-hand rule again. If we wrap our right hand around the loop with fingers in the direction of current flow (counterclockwise when viewed from above the loop), the thumb indicates the direction of the magnetic field at the center of the loop.

considering the second straight wire with a current of 1.0A, we can use the right-hand rule once more. Curling our fingers around the wire in the direction of the current (from top to bottom), the thumb points in the direction of the magnetic field.

By superposition, the total magnetic field at the center marked "x" is the vector sum of the magnetic fields from each wire. We add the individual fields based on their directions to find the resultant field at "x".

The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω

Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.

Answer: 3

Explanation: If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Answer:

The average velocity of the ball is 1.355 cm/s.

Explanation:

Given;

initial displacement of the ball, x₁ = 8.4 cm

final displacement of the ball, x₂ = 4.2 cm

initial time, t₁ = 3.0 s

final time, t₂ = 6.1 s

The average velocity of the ball is calculated as;

\(v = \frac{\Delta x}{\Delta t} \\\\v = \frac{8.4\ cm\ - \ 4.2 \ cm}{6.1 s - \ 3.0 s} \\\\v = 1.355 \ cm/s\)

Therefore, the average velocity of the ball is 1.355 cm/s.

She alternates between walking and running  so,  Jessica will walk 5 km and run 5 Km

Time taken by Jessica for walking : 5 km

Time taken to walk 1 km=5 minutes

Time taken to walk 5 km

=> 5 X 5

=>25 minutes

Time taken by Jessica for Running : 5km

Time taken to run 1 km = 15 minutes

=> 5 X 15

=>75 minutes

Total time taken   = Time taken by Jessica for walking + Time taken by Jessica for Running
