Answer:
1. Effect of air pressure
2. air- powered wheel chair
3. Pneumatic valves
Explanation:
1. In any pneumatic device, the mipact of air pressure to produce the moving effect on an heavy object is unexpected.
2. pneumatice demultiplexer when air in comprressed tank is allowed released to cause movement of the chair.
3. In industries, a pneumatic valve operates by force of air when actuated. A signal causes actuation of coil. When coil is energized, compressed high pressure air is allowe to enter in a small cylinder and cause operation of valve
Answer:
Because these subsystems interact with each other and the biosphere, they work together to influence the climate and make an affect on life all over the Earth.
Answer:
Answer explained below
Explanation:
The following is the nested if-else statement:
% if-based statement
if num < -2 || num > 4
f1(num)
else
if num <=2
if num >= 0
f2(num)
else
f3(num)
end
else
f4(num)
end
end
<u>NOTE:</u> the num is an integer variable that has been initialized and that there are functions f1, f2, f3 and f4.
The nested if-else statement can be replaced by switch statement as shown below:
switch num
case(0, 1, 2)
f2(num)
case(-2, -1)
f3(num)
case(3, 4)
f4(num)
otherwise
f1(num)
In this case, the switch based code is easier to write and understand because the cases are single valued or a few discrete values (not ranges of values)
Answer:
A=False
B=False
C=False
D=False
E=False
F=False
Explanation:
A. In an isothermal process, only the reversibly heat transfer is 0, 
B. Consider the phase change of boiling water. Here, the temperature remains constant but the internal energy of the system increases.
C. This is not true even in reversible process, as can be inferred from the equation in part A.
D. This is only true in reversible processes, but not in all isothermal processes.
E. Consider the phase change of freezing water. Here, the surroundings are increasing their entropy, as they are taking in heat from the system.
F. This is not true if 
, like in answer B. One case where this is true is in the reversible isothermal expansion (or compression) of an ideal gas.
