In a device like the one shown below, the cylinder is allowed to fall a distance of 300 m. As a result, the temperature of the w

Delvig [45]

Answer:

Increase in the temperature of water would be 0.9 degree C

Explanation:

As we know by energy conservation

Change in the gravitational potential energy of the cylinder = increase in the thermal energy of the water

Here we know that the gravitational potential energy of the cylinder is given as

$U = mgh$

here we have

h = 300 m

now we can say

$Mc\Delta T = (m \times 9.8 \times 300)$

now if the cylinder falls from height h = 100 m

then we have

$Mc\Delta T' = (m \times 9.8 \times 100)$

now from above two equations

$\frac{\Delta T'}{\Delta T} = \frac{100}{300}$

$\Delta T' = 2.7 \times \frac{1}{3} = 0.9 Degree C$

Order the speed of sound through these materials from the slowest to the fastest.

xz_007 [3.2K]

Answer:

1 ) Warm air

2) Cold air

3) Cold water

4) Steel

5) Hot molten

Explanation:

In order to solve this problem, we have to warn that the sound propagates more easily in denser media, in this way we have to identify the densities of the different materials.

Density cold air = 1.2 [kg/m^3]

Density warm air = 1.01 [kg/m^3]

Density cold water = 1000 [kg/m^3]

Density steel = 7500 [kg/m^3]

Density hot molten = 14100 [kg/m^3]

Therefore in order from the slowest to the fastest:

1 ) Warm air

2) Cold air

3) Cold water

4) Steel

5) Hot molten
