Answer:
Gay-Lussac’s law, because as the pressure increases, the temperature increases
Explanation:
First of all, we can notice that the volume of the tank is fixed: this means that the volume of the air inside is also fixed.
This means that in this situation we can apply Gay-Lussac's law, which states that:
"for a gas kept at constant volume, the pressure of the gas is proportional to the absolute temperature of the gas".
Mathematically:
where p is the pressure in Pascal and T is the temperature in Kelvin.
In this case, the tank is filled with air: this means that the pressure of the gas inside the tank increases. And therefore, according to Gay-Lussac's law, the temperature will increase proportionally, and this explains why the tank gets hot.
(a) 6.04 rev/s
The speed of the ball is given by:
where
is the angular speed
r is the distance of the ball from the centre of the circle
In situation 1), we have
r = 0.600 m
So the speed of the ball is
In situation 2), we have
r = 0.900 m
So the speed of the ball is
So, the ball has greater speed when rotating at 6.04 rev/s.
(b)
The centripetal acceleration of the ball is given by
where
v is the speed
r is the distance of the ball from the centre of the trajectory
For situation 1),
v = 30.6 m/s
r = 0.600 m
So the centripetal acceleration is
(c)
For situation 2 we have
v = 34.1 m/s
r = 0.900 m
So the centripetal acceleration is
Answer:
Answer:
the shoe which having heel of smaller crossection area.
Explanation:
Pressure is defined as the thrust acting per unit area.
Thrust is the force which acts on the surface perpendicularly.
Pressure = force / Area
Its SI unit is Pascal or Newton per square metre.
As both the shoes have same mass, so force is same but the area of crossection is different for both the shoes.
Teh shoe having heel of small crossection area exerts more pressure on another person's feet then the shoe having heel which has more crossection area.
