It takes 1 minute for 45 c to pass a point in a circuit, what is the current flowing through the circuit?
1 answer:
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:

As stated in the statement, we will apply energy conservation to solve this problem.
From this concept we know that the kinetic energy gained is equivalent to the potential energy lost and vice versa. Mathematically said equilibrium can be expressed as
Where,
m = mass
= initial and final velocity
g = Gravity
h = height
As the mass is tHe same and the final height is zero we have that the expression is now:
Answer:The mass of ball B is 10 kg.
Explanation;
Mass of ball A =
Velocity of the ball A before collision:
Velocity of ball A after collision=
Mass of ball B=
Velocity of the ball B before collision:
Velocity of ball B after collision=
The mass of ball B is 10 kg.
