It would be B because it makes science to the topic
no it would in fact decrease your blank energy
Answer: If both gases undergo the same entropy then more heat is added to gas a because the entropy of the gas a is less than the entropy of the gas b.
Explanation:
Entropy is defined as the degree of randomness. When the temperature of the gas increases then the entropy of gas also increases.
In the given problem, Quantity a of an ideal gas is at absolute temperature t, and a second quantity b of the same gas is at absolute temperature 2t.
Heat is added to each gas, and both gases are allowed to expand isothermally. It means that the volume is constant during this process.
If both gases undergo the same entropy then more heat is added to gas a because the entropy of the gas a is less than the entropy of the gas b. If the heat is added then there will be more entropy.
Answer:
f = 2ππ √g / A
Explanation:
The expression that describes the simple harmonic movement is
x = A cos (wt + Ф)
So that the penny should the surface when the system is going down the system must in faster than the acceleration of gravity, let's look for this acceleration
v = dx / dt
a = dv / dt = d²x / dt²
.a = - A w² cos (w t + Ф)
The maximum value of this acceleration is when the cosine value ±1
a = A w²
For the penny to leave the surface the limit acceleration is
a = g
g = A w²
w² = g/A
w = 2π f
g / A = 4 π² f²
f = 2ππ √g /A
For values greater than this frequency the penny separates from the surface in the downward movement
Answer:
2.5 m/s
Explanation:
you have to subtract 5 meters because you start at 5 meters. so Just take (30m-5m)/10s=2.5m/s
