One end is sealed to prevent air from disturbing the scale and measures. Therefore, a Mercury Barometer works on the principle of balancing the atmospheric pressure with the volume of mercury present in the device
Answer:1.28v/k
Explanation:
Thermoelectric power is the same as Seebeck coefficient.
So the formula is S =Vemf/Th - Tl
= 12.8/310-300
S= 12.8/10
=1.28V/T
Answer:
g = 12.22 m/s²
Explanation:
The time period of this pendulum is given as follows:

but the formula for the time period of a simple pendulum is as follows:

where,
L = length of pednulum = 48 cm = 0.48 m
g = magnitude of th gravitational acceleration on this planet = ?
Therefore,

<u>g = 12.22 m/s²</u>
Answer: Option (A) is the correct answer.
Explanation:
Relation between kinetic energy and temperature is as follows.
As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.
And, when gas particles move slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.
Thus, we can conclude that temperature will increase best describes the outcome of increasing the kinetic energy of the molecules in the above picture.
Explanation:
gas vibrate and move freely at high speeds, liquid vibrate, move about and slide past each other. solid vibrate (jiggle) but generally do not move from place to place
