Answer:
8400 N
Explanation:
We are given that
Mass,m=1.2 kg
Initial speed,u=-8 m/s
Final speed,v=6 m/s
Time,
We have to find the magnitude of the average force on the ball during this collision.
Change in momentum,=
Average force,
Using the formula
Hence, the magnitude of the average force on the ball during this collision=8400 N
E is always less than or equal to Eo, so the dielectric constant is greater than or equal to 1. The larger the dielectric constant, the more charge can be stored, therefore its greater most of the time
Doubling the size of a load resistor increases the load current. Increasing the load resistance, in turn the total circuit resistance is reduced. The load current would not be half as much since when you increase the size of load resistor then load current increases.
To get it to start moving, he have to exert a force equal to its maximum force of static friction.
F= fs,max = Ms m g= (0.21) * (180) * (9.8) = 370 N
Let me know if im wrong but if not brainliest user for helping or best answer
