Answer:
I can answer it but wats the experiment exactly?
Answer:
35 N to the right
Explanation:
When calculating net force when both forces are on the same side you add them when they are going against each other you subtract them.
Answer:
108 km
Explanation:
The conversion factor between meters and feet is
1 m = 3.28 ft
So the second altitude, written in feet, can be rewritten in meters as
or in kilometers,
the first altitude in kilometers is
so the difference between the two altitudes is
Answer: 5.8 kg m/s
Identify the given information.
m = 0.145 kg
v = 40.0 m/s
Choose which formula you should use. In this case, you are finding momentum.
p = mv, where p is momentum.
Substitute and solve.
p = 0.145 kg x 40.0 m/s
p = 5.8 kg m/s
<u>Answer: </u>
<em>Considering the II law of thermodynamics</em>
<em>From the figure</em>
<em>Out put of energy: </em>
Heat supplied from the source/ reservoir (Q₁) - Heat rejected to the surroundings from the system (Q) = Q₁ - Q₂. Also known as Net work done on the system.
<em>Input of energy: </em>
Amount of heat energy supplied to the system from the source (Q₁ ).
Efficiency (H.E) = η = Output÷ Input
η = (Q₁ - Q₂) ÷ Q₁
OR η = Wnet ÷ Q₁ ; since Wnet = (Q₁ - Q₂)
