Weathering the process that breaks down exposed stone and rock causing it to split apart or wear away. Different forces can cause rocks to become weathered physical weathering is caused by purely mechanical changes to the rock while chemical weathering is caused by chemical reactions
This is true because they are the same type of pole.
A=F/m
=5/12
=0.42 m/s^2
Since the ball stops, it decelerates at a rate of 0.42 m/s^2 before stopping and it’s final velocity is 0 m/s.
t=(u-v)/a
=(20-0)/0.42
=48 s
The answer is A. Because if you're increasing the power than the strength will increase.
Answer:
The banking angle is 23.98 degrees.
Explanation:
We have,
Radius of a curve is 35 m
Speed of a car is 7 m/s
It is required to find the banking angle. At equilibrium, net force is equal to the centripetal force between vehicle and the road such that the banking angle is given by :
g is acceleration due to gravity
So, the banking angle is 23.98 degrees.
