Newton's 2nd Law says the acceleration of an object depends on its ______ and the amount of _______ acting on it.
maksim [4K]

Answer:

Newton's 2nd Law says the acceleration of an object depends on its <u>mass </u>and the amount of <u>net force</u> acting on it.

Explanation:

Definition of acceleration:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Δv/Δt

a = acceleration

Δv = change in velocity

Δt = change in time

Units:

The unit of acceleration is m.s⁻².

Acceleration can also be determine through following formula,

F = m × a

a = F/m

This is the newton's second law:

"The acceleration of an object depends on its <u>mass </u>and the amount of <u>net force</u> acting on it"

The acceleration is depend directly on the force while inversely on the mass.

Two tanks (tank A and tank B) of gas are connected by a closed valve. Tank A is 5 liters and contains O2 gas at a pressure of 24
Inessa [10]

Answer:

15 atm

Explanation:

Tank A is V₁ = 5 liters and contains O₂ gas at a pressure (P₁) of 24 atm. When it is connected to tank B, the total volume V₂ is 5 L + 3 L = 8 L. We can calculate the final pressure (P₂) of O₂ using Boyle's law (assuming ideal behavior and constant temperature).

P_{1}.V_{1}=P_{2}.V_{2}\\P_{2}=\frac{P_{1}.V_{1}}{V_{2}} =\frac{24atm.5L}{8L} =15atm

The pressure of O₂ is independent of the pressure of N₂.
