Contact forces has to be touching for it to be an actual force. A field force does not have to be touching but it does have to be acting on particles at different positions in a space.
Based on the data, the car would reach a final velocity of 0 m/s. With a mass of 1500 kg, the momentum would be -15000 kg.m/sThank you for your question. Please don't hesitate to ask in Brainly your queries.
If we compare the energy of visible light to the energy of X-rays, we find that X-rays have a much higher frequency. Usually, electromagnetic radiation with higher frequency (energy) have a higher degree of penetration than those with low frequency.
Explanation:
P =F * v
F = m * a = 65 kg * 9.81 ms^-2 * 12 passengers
v = d/t = 150m / 64 s
I think you can calculate and substitute this units should be watts
Answer:
12010
Explanation:
Given:
power time
4,370 25
4,420 22
4,150 26
To find: difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount
Solution:
Energy = power × time
For clothes dryer x:
energy = 4370 × 25 = 109250
For clothes dryer y:
energy = 4420 × 22 = 97240
For clothes dryer z:
energy = 4150 × 26 = 107900
Dryer x uses the greatest amount of energy and dryer y uses the least amount of energy.
Difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount = 109250 - 97240 = 12010
