Answer:
work is 50 kj
Explanation:
Given data
heat (Q) = 50 kj
To find out
work input for the compression stroke per kilogram of air
Solution
we will apply here "first law of thermodynamics" i.e.
The First Law of Thermodynamics states that heat is a form of energy, subject to the principle of conservation of energy, that heat energy cannot be created or destroyed. It can be transferred from one location to another location. i.e.
ΔU = Q – W ................1
here ΔU is change in internal energy, Q is heat and W is work done
here U = 0 because air compressor the compression takes place at a constant internal energy in question
so that by equation 1
Q = W
and Q = 50
so work will be 50 kj
Water supply.
Food production.
Housing and shelter.

Answer:
Do you need shown work for all of this?
Answer:
A moving player may only take 2 legal steps after catching the ball to shoot, pass or to come to a stop.
so (B. 2)
Explanation:
On this play, the offensive player catches the ball in the air and lands with a left, right, left prior to shooting. This is a traveling violation for taking 3 steps.
Answer:
maximum roll-off factor is 0.7
Explanation:
given data
rate of output data = 1,000,000 bits/sec
cutoff frequency fc = 850 kHz
solution
we know bandwidth frequency is same as that of bandwidth
we apply here fc formula that is
fc = ω ( 1 + α ) ..........1
here
ω = data rate ÷ 2 .............2
ω = 1000 ÷ 2
ω = 500000 Hz
so put now value in eq 1
fc = ω ( 1 + α )
850000= 500000 ( 1 + α )
solve it we get
α = 0.7
so, maximum roll-off factor is 0.7
