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:
Answer:
Explanation:
given,
A woman can see object between 45 cm and 155 cm
glasses is 2 cm from the eye
to able to read a book distance = 25 cm
For the object distant apart
hence, D = - 0.653 m
For the object at the near point
hence, D = 2.02 m
Elastic potential energy is given by:
Where k is the spring constant in N/m and x is displacement from equilibrium position in m. Evaluating:
A/ The potential energy is stored in the spring is 44.1 J.
