The ability of Torricelli's hypothesis about atmospheric pressure to suggest the design of the barometer is an illustration of Fruitfulness
A barometer is a scientific instrument used to measure the air pressure in a certain environment. The atmospheric pressure measured is also known as barometric pressure. The pressure is measured in terms of atmosphere ( atm ) or bars. One bar / atm = 100 KPa
A glass tube closed at one end is submerged in a bowl filled with mercury and raised the tube but not above the mercury surface. The weight of the mercury pulled it down and left a partial vacuum at the closed end. This proved that gas has mass by creating pressure on things around it.
Therefore, the ability of Torricelli's hypothesis about atmospheric pressure to suggest the design of the barometer is an illustration of Fruitfulness

Answer:
Answer is 3.
Explanation:
Start by putting the values in the formula i.e.
Lenght 1.2m
The speed of sound through the pipe 340m/s.
Put it in the formula and the answer is 3.

Answer:
Displacement is fundamental unit
Answer:
The distance traveled by the skier is 5.309 km
Solution:
As per the question:
Mass of the skier, m = 64 kg
Coefficient of friction between the ski and the snow, 
Mass of snow, M = 5.0 kg
Now,
To calculate the distance, 's' traveled by the skier, in order to melt 5.0 kg of snow:
We know that:
where
= coefficient of friction
N = Normal Reaction
N = mg
Thus
(1)
Also,
(2)
where
= Latent Heat of fusion
Thus from eqn (1) and (2):
s = 5.309 km
