The surrounding air will become warm when water vapor condenses. The vapors when become water will give away latent heat they have, we know that latent heat is required for the object to change states, so, the latent heat the water vapor had when it became water vapor from water will be given out when it again becomes water.
The two forces should be equal therefore:
2.10 * Fa = Fa + 2 * F * cos 18
simplifying the right side:
2.10 * Fa = Fa + 1.902 * F
1.10 Fa = 1.902 F
<span>F / Fa = 0.578</span>
Answer:
Mass of another particle, m = 46 kg
Explanation:
it is given that,
Mass of first particle, m₁ = 28 kg
Gravitational force, 
Distance between the particles, d = 3.2 m
We need to find the mass m of another particle. It is given by the formula as follows :



m = 45.5 kg
or
m = 46 kg
So, the correct option is (d) "46 kg". Hence, this is the required solution.
To begin to lift the car, a hydraulic jack must produce <em>more than 9,800N</em> of force.
To keep the car in position once it is lifted, the jack must produce <em>exactly 9,800N</em> of force.
