Answer:
voltmeter (C. Volts)
Explanation:
The amount of electrical potential is measured by voltmeter. Electrical potential is the amount of work needed to move a unit electric charge from a reference point to the specific point in an electric field. <u>The SI unit of electrical potential is Volt</u>.

For Fraunhofer diffraction at a single slit would be represented by:
<span>a sinθ = mλ
</span><span>It should be noted that the angle needs be halved because we are only concerned with the angle between m=1 and m=0 and they gave you the angle between m=1 to the right of the center and m=1 on the left of the center. We calculate as follows:

<span>a sin(45/2)=(1)(470)
a = 1228 nm
Hope this answers the question. Have a nice day.

Answer & Explanation:
Definition:
Mass informs us about how much matter is present in a body. It is the measure of the inertia of a body. It can be measured by measuring the force of gravity acting on it on earth.
On the other hand, Momentum is the quantity of motion of the body. It depends depends upon velocity and the direction of the motion of the body.
Unit:
The SI unit of mass is kilogram (kg) while the SI unit of momentum is kg.m.s-1.
Formula:
Mass = Momentum / Velocity
Momentum = Mass * Velocity
or p = mv
Type:
Mass is scalar quantity while Momentum is a vector quantity.
Answer:
v = 1.6 m/s
Explanation:
Given that,
Distance, d = 72 m
Time taken, t = 45 s
We need to find their average velocity. Average velocity of an object is given by total distance divided by total time taken.
So, their average velocity is 1.6 m/s.
