Therefore, the volume of the gas at temperature 100°C is 4.62L

Explanation:

Given-

Volume, V1 = 4L

Temperature, T1 = 50°C = 50 + 273K = 323K

Temperature, T2 = 100°C = 100 + 273K = 373K

Volume, V2 = ?

Using Charles law:

V1/T1 = V2/T2

4/323 = V2/373

V2 = 4.62L

Therefore, the volume of the gas at temperature 100°C is 4.62L

An Austin volleyball player bumps a 5 kg ball into the air. It reaches a height of 2.8 meters. How fast was the ball going as it

KATRIN_1 [288]

Answer:

v = 7.4 m/s

Explanation:

Given that,

Mass if a volleyball, m = 5 kg

The ball reaches a height of 2.8 m

We need to find how fast the ball is going as it bumped into the air. Ket the velocity is v. Using the conservation of energy to find it as follows :

$mgh=\dfrac{1}{2}mv^2\\\\v=\sqrt{2gh} \\\\v=\sqrt{2\times 9.8\times 2.8} \\\\=7.4\ m/s$

So, the required speed is 7.4 m/s. Hence, the correct option is (b).
