The correct answer is letter C, regular reflection.
<span>An image seen in a smooth dinner plate is an example of a
regular reflection. This phenomenon only occurs in smooth and polished surfaces.
During this stage light occurs at a certain angle and is reflected back at the
same angle producing reflections in a way like a mirror does this commonly.</span>
Answer:
Explanation:
Let us assume that the radius of the wire, r = 0.8 mm = 0.0008 m
EMF of the battery, V = 12 V
Slope of I versus 1/d, m = 600 A-m
The resistance of any material is given by :
d is the length of wire
Since,
So, the resistivity of the material of which the wire is made is .
Answer:
Electrical energy
Explanation:
electrical energy Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
The impulse exerted on the ball by the wall is 24i kgm/s.
<h3>
Impulse exerted by the ball on the wall</h3>
The impulse exerted by the ball on the wall is the change in the linear momentum of the ball.
J = ΔP
ΔP = Pf - Pi
P = mv
where;
- m is mass of the ball
- v is the velocity
ΔP = 3(4.0i + 3.0j) - 3(-4.0i + 3.0j)
ΔP = (12i + 9j) - (-12i - 9j)
ΔP = 24i kgm/s
Thus, the impulse exerted on the ball by the wall is 24i kgm/s.
