Given
Mass of mother
Mother is released with a speed of
Assuming we need to find elastic Potential energy stored in Trampoline
Kinetic energy acquired by Mother comes from Elastic Potential Energy stored in the spring
I.e. Elastic Potential Energy=Kinetic Energy of mother
So 246.875 J of Energy is stored in the trampoline as he pull the ring
Answer:
0.75 A
Explanation:
An electric current is a flow of charged particles.
A current is defined through its intensity, which is given by:
where
I is the current intensity
q is the charge passing through a given point in the circuit
t is the time it takes for the charge q to pass that point in the circuit
In this problem, we have:
q = 45 C is the charge passing through the point in the circuit
is the time elapsed
Therefore, the current intensity is:
