We can use Newton's second law to find out. This says F=ma, where m is the mass we seek:
So we see the mass is 3kg
Explanation:
A positive point charge Q is fixed on a very large horizontal friction less tabletop. A second positive point charge q is released from rest near the stationary charge and is free to move.
As per the law of conservation of energy the change in kinetic energy is equal to the change in potential energy.
The mathematical expression for the conservation of energy is given by :
On solving the above equation, we get the value of v as :
In the above expression, as the term increase, as increases, the value of decreases. So, the correct option is (B) "As it moves farther and farther from Q, its speed will increase".
It should be S since S stands for students. Giving the team with more members the upper hand. Hope this helps.
S=(0x4)+(0.5x4.81x4x4)
S=0.78.48
The depth is approximately 78 meters.
(My brain hurts now) :P Good Luck!
Answer: An object is accelerating if it is changing its velocity.
