Answer:
4
Explanation:
As you can see in the free body diagram there are 4 forces acting on the body.
Answer:
Force = mass × acceleration
Explanation:
The amount of force required to drag the object across the table is the product of the mass of the object and acceleration
Answer:
work done = 117 kJ
Explanation:
given data
mass m = 3 kg
constant pressure P = 200 kPa
temperature T = 200°C
solution
we know that work done by steam is express as
work done = pressure × ΔVolume ....................1
and here ΔVolume = final volume - initial volume
we use here steam table and get at pressure 200 kPa
final specific volume = 1.08052 m³/kg
and
initial specific volume = 0.885735 m³/kg
so here
ΔV = 3 × (1.08052 - 0.885735)
ΔV = 0.584 m³
so put value in equation 1 we get
work done by steam = 200 × 0.584
work done = 117 kJ
What is the constant velocity?
<span>We need that number in order to solve the problem
</span>Or
<span>It has a graph in which it describes the different acceleration</span>
Answer:
the answer should be a constant
hope this helps!!
