Answer:
wont help at all its useless lolz
Explanation:
Answer:false
Explanation:
Given
Two equal positive charge are held in place at a fixed distance
Suppose q is charge and 2d is the distance between them
Suppose is the third charge which is placed d distance apart from q
Now the force by charge q will make the charge to move right while other charge cause the charge to move left.
Overall forces by charge q will cancel out each other
Now electrical Potential Energy
It is clear that
Therefore above statement is false.
Answer:
1.3 m/s
Explanation:
It is given that,
Mass of bird A,
Mass of bird B,
Initial speed of bird A is 0 as it was at rest
Initial speed of bird B is 3 m/s
We need to find the velocity of the center of mass for this system of two birds. Let it is V. so,
So, the center of mass for this system is 1.3 m/s.
Answer:
F = -2527.35 N
Explanation:
Given,
mass per unit time = 58.1 Kg/s
Speed of the water = 43.5 m/s
Final momentum = 0 kg/s
Force = Change in momentum
F = Final momentum - initial momentum
F = 0 - initial momentum
F = -2527.35 N
Hence, the Force exerted is equal to F = -2527.35 N
Answer:
The kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.
