i think not too sure but yea
For this case, the first thing we are going to do is define a reference system.
We define the vertical axis of the reference system, pointing upwards.
Therefore, doing summation of forces in vertical direction we have:
Then, since we want the net force to be equal to zero, then:
From here, we clear the force that we must apply on the object:
The positive sign means that the force points upwards.
Answer:
to create a net force of zero on the object you must apply:
33 Newton upwards.
Answer:
Explanation:
V = Volume of air =
P = Power = 10 W
t = Time = 1 hour
m = Mass of air = 2 kg
Specific volume is given by
The specific volume at the final state is
Work done is given by
The energy transfer by work, is
Change in specific internal energy is given by
The change in specific internal energy of the air is
The basic formula for power is P=W/t meaning it is the rate at which work is accomplished.
