Eric throws a basketball straight up into the air. As it rises, which form of energy is increasing? A. elastic potential energy
2 answers:
Answer:
C) Gravitational potential energy
Explanation:
As ball is thrown upwards then we can say that speed of the ball will decrease as it will move upwards.
This is due to gravity which act opposite to the motion of the ball
So as the ball is thrown upwards the initial kinetic energy of the ball will start decreasing as it will move upwards
Here we also know that gravitational potential energy of the ball is given as
so as the ball start rising upwards the potential energy of the ball will increase
so here correct answer will be
C) Gravitational potential energy

To solve this problem it is necessary to apply the concepts related to transformers, that is to say passive electrical device that transfers electrical energy from one electrical circuit to one or more circuits.
From the mathematical definition we have that the relationship between the voltage of the first coil and the second coil is proportional to the number of loops of the first and second loop, that is:
Where
input voltage on the primary coil.
input voltage on the secondary coil.
number of turns of wire on the primary coil.
number of turns of wire on the secondary coil.
Replacing our values we have:
Replacing,
From the same relations of number of turns and the voltage of the first and second coil we also have the relation of electricity and voltage whereby:
Where
= Current Primary Coil
= Current secundary Coil
Therefore:
Therefore the maximum values for the secondary coil of the voltage is 410.56V and Current is 1.87A
