Period = (1/frequency) .
If frequency is 100 per second, then
Period = (1) / (100 per second) = 0.01 second .
The relative humidity is 100%.
To find the answer, we have to know about the relative humidity.
<h3>What is the relative humidity?</h3>
- The amount of water vapor in the air is referred to as humidity.
- The gaseous and invisible condition of water is called water vapor.
- Humidity can be expressed in a variety of ways, including absolute humidity, relative humidity, mixing ratio, and dew point temperature.
- Relative humidity can be expressed as,
- Here, it is given that, the vapor pressure is the same as the saturation vapor pressure, thus,
Thus, we can conclude that, the relative humidity is 100%.

Answer:
A:- 50 J
B:- 500 J
Explanation:
a) Given that a 25 N force is applied to move the box. Also the floor is having friction surface.
So in order to move the box, the floor should have friction of atleast 25 N.
∴ friction = 25 N
Work done = force * displacement of box
Given, the box is moved 2 m across the floor
So, Work done = friction * 2 m
= 25 * 2
= 50 J
b) Given, the box is having weight of 250 N weight
Gravitational force is acting on the box which is equal to (mass * gravity)
∴ Force = 250 N
The box is lifted 2 m above the floor.
So, displacement = 2 m
Work done = force * displacement of box
Work done = 250 * 2
= 500 J
Answer:
3rd choice
Explanation:
heat is transfered causing it to melt
The potential difference does work on the electron. The work is given by:
W = Vq
W = work, V = potential difference, q = electron charge
Given values:
V = 6V, q = 1.6x10^-19C
Plug in and solve for W:
W = 6(1.6x10^-19)
W = 0.96aJ
