The answer is B. desert. Deserts don't get much rainfall to begin with and most of it evaporates.
Answer:
123 J transfer into the gas
Explanation:
Here we know that 123 J work is done by the gas on its surrounding
So here gas is doing work against external forces
Now for cyclic process we know that

so from 1st law of thermodynamics we have


so work done is same as the heat supplied to the system
So correct answer is
123 J transfer into the gas
Answer:
3.67 km
Explanation:
Joe distance towards coffee shop is,

And the Max distance towards bookstore is,

Now the distance between the Joy and Max will be,
By applying pythagorus theorem,

Substitute 0.40 km for OB and 3.65 km for OA in the above equation.

Therefore the distance between there destination is 3.67 km.
Answer:
T1 = 130N, T2 = 370N
Explanation:
In order for the system to be at rest, the sum of all forces must be zero and the torque around a point on the beam must be zero.
1. forces:
Let tension in rope 1 be T1 and in rope 2 be T2:
ma = T1 + T2 - 100N - 400N = 0
(1) T1 + T2 = 500N
2. torque around the center point of the beam:
τ = r x F = 5*T1 + 3*400N - 5*T2 = 0
(2) T1 - T2 = -240N
Solving both equations:
T1 = 130N
T2 = 370N
