Answer:
No, the isothermal process is the not same as an adiabatic process for an ideal gas.
Explanation:
There is no change in the internal energy of an ideal gas undergoing an isothermal process since the internal energy depends only on the temperature.
But in the adiabatic process, there is no heat transfer, but work transfer can take place which causes the change in the internal energy due to which there is a change in temperature of an ideal gas.
Hence, the isothermal process is the not same as an adiabatic process for an ideal gas.
Answer:
A
Explanation:
So a pulse is a part of a mechanical wave, and mechanical waves are energy transfer trough some medium, in this case a stretched spring. So the correct answer is (A) energy only. The pulse cant be transferred into mass.
The equation for Kc:
Kc = [C]² / [A] [B]
Let the equilibrium concentration of C be x
Then,
the equilibrium concentration of A = 1-x
the equilibrium concentration of B = 1-x
The equation becomes:
4 = x² / (1 - x)²
3x² - 8x + 4 = 0
x = 2, x = 2/3
The first answer is not possible so x = 2/3
[A] = 1 - 2/3 = 1/3
[B] = 1 - 2/3 = 1/3
1. the max height is solved from v = square root of 2 gy where g is equal to 9.8 m/s2/ hence y is equal to 8.62 meters.

2. time at max height is solve when velocity = 0. ( 0 = -9.81*t +13); t = 1.325 seconds
3. time required for the entire trip is 2*1.325 equal to 2.65 seconds.
4. without air resistance, the velocity just before the ball hits the ground is the same as its initial velocity, 13 m/s.</span>
