I'm pretty sure it stands for the speed of light
Answer:Friction force
Explanation:
The frictional force is responsible for stopping the moving object.
The friction force is provided by nature in the form of air resistance, fluid resistance, Surface resistance.
For surface resistance, the friction force is of two types namely kinetic friction force and static friction force.
Static friction acts when the object is stationary and a force is applied to cause the motion while kinetic friction acts when the body starts moving.
kinetic friction is lesser is in magnitude as compared to static friction.
Answer with Explanation:
We are given that
Velocity of uranium=v=0.94 c
Speed of piece A relative to the original nucleus=
Speed of piece B relative to the original nucleus=
Velocity of piece A observed by observer
Substitute the values
Velocity of piece B observed by observer
The velocity of piece A and piece B as measured by an observer in the laboratory are not same.
Answer:
Explanation:
first ball rolls on the porch by total distance
Then again it will move on horizontal floor
also in vertical direction it will drop down
so we have
so magnitude of net displacement of the ball is given as
