Joules, or the unit of work, is derived from the equation of Newton multiplied to distance. That is, the force applied to an object is multiplied to the distance it travelled when the force is applied to it. Thus, the formula of Joules would be Newton x distance. taken into their units, it would look like as J = N x d. Now in this problem, the missing variable would be distance since it is the distance that was asked. The given variables would be the force and the work done. What happens would be that the work done is divided by the force exerted to get the distance. So, 500 Newtons would be divided to 250 Joules. It would look like this
250 J / 500 N = ?m
the answer would be 0.5m
0.5m would be the distance that pertains as to how high she jumped.
Gravel, due to the weight of the batteries on that of the wooden pallet, it is likely to sink in the sand slightly, whereas as gravel has a larger surface area, it will support the weight and not be difficult to remove after storage.
Answer:
The change in momentum of the car is 16380.8 kg.m/s
Explanation:
Given;
mass of the car, m = 1600 kg
time of motion, t = 4.20s
force of friction on the car, F = 3900 N
final velocity of the car after the brakes were applied, v = 0
The initial velocity of the car during the motion is calculated as;
The change in momentum of the car is calculated as;
ΔP = mu
ΔP = 1600 x 10.238
ΔP = 16380.8 kg.m/s
Answer:
because fm radio waves are affected by tall buildings or tall objects but am radio wave are affected storms
Explanation:
Answer:
refraction
Explanation:
When a ray of light passes from one medium to another medium, it deviates from its path, this phenomenon is called refraction.
When the ray passes from rarer medium to denser medium it bends towards the normal and if the ray passes from denser medium to rarer medium, it bends away from the normal.
Here, the ray passes from air to glass, so refraction takes place.
