The speed resulting from the plane is (3) 226 m/s
Reasoning:
We can determine the plane's resultant speed using the Pythagorean Theorem because the two speeds form a right angle (creating a right triangle).
Thus, the computation is as follows:
Consequently, the plane's resultant speed is (3) 226 m/s
Have a wonderful day!
Answer:
Incomplete question: "Each block has a mass of 0.2 kg"
The velocity of the center of mass for the two-block system just prior to their collision is 2.9489 m/s
Explanation:
Provided information:
θ = angle of the surface = 37°
m = mass of each block = 0.2 kg
v = speed = 0.35 m/s
t = collision time = 0.5 s
Question: What is the velocity of the center of mass for the two-block system right before the blocks collide, vf =?
Change in momentum:
It’s essential to calculate the required force:
Here, g = acceleration due to gravity = 9.8 m/s²
Heat supplied to the gas = Q = 743 Joules
Work applied to the gas = W = -743 Joules
The Ideal Gas Law that should be remembered is:
P = Pressure (Pa)
V = Volume (m³)
n = number of moles (moles)
R = Gas Constant (8.314 J/mol K)
T = Absolute Temperature (K)
Now, let’s proceed with the problem!
Given:
Initial volume of the gas = V₁ = 2.00 L
Initial pressure of the gas = P₁ = 5.00 atm
Unknown:
Work done on the gas = W =?
Heat supplied to the gas = Q =?
Solution:
An ideal gas expands isothermally:
Next, we will determine the work performed on the gas:
By utilizing the methodology mentioned earlier:
Next, we will ascertain the work completed on the gas:
Ultimately, we can calculate the total work done and heat supplied as follows:
