Answer:
a.Internal temperature change is 90.49°F
b.Internal energy change is -2.43Btu/lbm
Explanation:
The energy balance for this steady-flow system can be expressed as:
Therefore,
#Since:
From tableA-1
#Replacing the values in the equation:
We have that
F = M*A
200N*10KG is 2000 newtons
so 2000 newton's is the normal force that is being exerted on the block
Answer:
The net force is zero.
Explanation:
Two opposing and equal forces cancel each other out, giving you a net force of zero.
1. Frequency is the number of complete waves that pass a point in a second. 2.Wavelength is the distance between two crests or two troughs. 3.Time period <span> is the time it takes for one complete wave to pass a given point. 4. Amplitude is the height of the wave. Hence option 4 is correct. </span>
