Agata [3.3K]3 years ago
6 0

Answer:

20.The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is

A cyclist moving with a constant velocity of 6.0 m/s forward passes a car that is just starting. If the car has a constant accel
sergiy2304 [10]

After 6 seconds, the car will surpass the cyclist.

<h3><u>Explanation:</u></h3>

The speed of the cyclist = 6 m/s.

Let after time t sec, the car will overtake the cyclist.

So, distance covered by the cyclist in t sec = 6t m

Initial velocity of the car is 0 m/s, because the car is just starting.

Acceleration of the car =2 m/s^2.

Final velocity of the car =6 m/s.

So to cover the distance 6t, the time required by the car = \frac{1}{2} \times a \times t^2 = \frac{1}{2} \times 2 \times t^2

6t = \frac{1}{2} \times 2 \times t^2\\6t = t^2

t =6 sec

So, after 6 seconds, the car will surpass the cycle.

What is the potential energy of a falling rock if it has a mass of 64 kg and fell from a height of 54 m
Talja [164]

<u>P.E (Potential Energy) = 33868.8 J</u>

<u>Explanation:</u>

The formula to calculate Potential energy is:

PE = mgh

where PE = potential energy

m = mass of an object

g = acceleration due to gravity

h = height of the object

Here, m = 64 kg

         g  =  9.8 m / s^{2}

         h  = 54 m

So, substituting the values in the formula:

PE = mgh

    = 64 × 9.8 × 54

    = <u> 33868.8 J</u>
