Answer:
F = 7,916,955.0N
Explanation:
According to newtons second law
Force = mass * acceleration
Given
mass = 52.0kg
distance S = 22.0m
time t = 17.0 ms = 0.017s
We need to get the acceleration first using the formula;
S = ut+ 1/2at²
22 = 0 + 1/2 a(0.017²)
22 = 0.0001445a
a = 22/0.0001445
a = 152,249.13m/s²
The magnitude of the average force exerted will be;
F = ma
F = 52 * 152,249.13
F = 7,916,955.0N
Answer:
Because the speed of sound travels at +- 1300 km/h and the car that is approaching isn't that fast. So u first hear the sound before the car reaches u.
i hope it helps
Explanation:
Explanation:
Power = change in work/change in time
P = 600 joules/ 4 seconds
P= 150 watts
hope this helps :)
Finally, the amount of increased volume<span> that is achieved by an increase in </span>amplitude<span>is also affected by the frequency. So, turning the </span>amplitude<span> level in the mid-range sound from the previous example will not have the same proportional effect on loudness as the bass sound.</span>
B.
look at you shoelaces they are not hard, don't move like a liquid, or have a high density.<span />
