what happens at Point C is sublimation. the increase in temperature affects the Vapour pressure soon as you can see the curve is increasing with increasing pressure there is increase in temperature that is the sublimation Curve
Answer: <span>D. A bimetallic strip bends so that the steel is on the outside curve

When something has an increased temperature, its volume will expand. Then, if the temperature drops, its volume should be smaller. From there option A and B are out since the liquid in thermometer is expand or move up.
When you put two kinds of different metal with a different coefficient of thermal expansion, the outer curve metal will be the one with lesser coefficient when temperature drop. Since the question about drop in temperature then the metal should be bend
Brass will expand 1.5 times more than the steel so the outer curve would be the steel.
Answer:
Yes, because the wrench is moving at the same speed as the sailboat.
The main difference is that a person on the ground would see the wrench moving diagonally, while a person on the boat would see the wrench falling straight down,
This difference in paths lead to the relativistic change in lengths.
Honestly, giving. I know that receiving may feel very good, and you get that new thing that you wanted but if you give, you feel really good when you see that smile on someone else’s face.
Answer:
200 N/m
20 rad/s
0.31415 seconds
3.18309 Hz
Explanation:
m = Mass of glider = 0.5 kg
x = Displacement of spring
F = Force on spring = 6 N
From Hooke's law we have relation
The spring constant is 200 N/m
Angular frequency is given by
The angular frequency is 20 rad/s
Frequency is given by
The frequency is 3.18309 Hz
Time period is given by
The time period is 0.31415 seconds
