Read the scenario, then answer the questions. a 2 kg ball is thrown upward with a velocity of 15 m/s. what is the kinetic energy
2 answers:
Explanation:
We have,
Mass of the ball is 2 kg and it is thrown upward with a velocity of 15 m/s.
It is required to find the kinetic energy of the ball as it is being thrown. The kinetic energy is possessed due to the motion of motion. It is given by :
Let potential energy of the ball when it gets to its maximum height just before falling back to the ground will be equal to the kinetic energy i.e. 225 Joules. As the energy of the system remains conserved.

Answer:
P=(2 nm, 8mn)
Explanation:
Given :
Position of positively charged particle at origin,
Position of desired magnetic field,
Magnitude of desired magnetic field,
Let q be the positive charge magnitude placed at origin.
<u>We know the distance between the two Cartesian points is given as:</u>
<u>For the electric field effect to be zero at point D we need equal and opposite field at the point.</u>
as we know that the electric field lines emerge radially outward of a positive charge so the second charge will be at equally opposite side of the given point.
assuming that the second charge is placed at (x,y) nano-meters.
Therefore,
and
