Answer:
When the temperature of the gas is increased from 20 to 40, the pressure will be 2p
Explanation:
Given;
initial temperature of the gas, T₁ = 20 K
final temperature of the gas, T₂ = 40 k
initial pressure of the gas, P₁ = P
final pressure of the gas, P₂ = ?
Apply pressure law of gases;
Therefore, when the temperature of the gas is increased from 20 to 40, the pressure will be 2p
Answer:
2.55 m/s
Explanation:
A 3.00-kg crate slides down a ramp. the ramp is 1.00 m in length and inclined at an angle of 30° as shown in the figure. The crate starts from rest at the top, experiences a constant friction force of magnitude 5.00 N, and continues to move a short distance on the horizontal floor after it leaves the ramp. Use energy methods to determine the speed of the crate at the bottom of the ramp.
Solution:
The work done by friction is given as:
The work done by gravity is:
