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.

Answer:
The pressure exerted by the girl is 245,000 N/m²
Explanation:
Given;
mass of the girl, m = 50 kg
area of the girl's shoe, A = 0.002 m²
The pressure exerted by the girl is calculated as follows;
Therefore, the pressure exerted by the girl is 245,000 N/m²
Explanation:
In Single Slit Experiment:
The width of the central diffraction maximum is inversely proportional to the width of the slit.
Therefore, if we make the slit width smaller, the angle T(representing the angle between the wave ray to a point on the screen and the normal line between the slit and the screen) increases, giving a wider central band.
Answer:
d = 369.38 km
Explanation:
The speed has a x-component and a y-component.
speed,x = 2.07cos(28.8°) = 1.81 km/s
speed,y = 2.07sin(28.8°) = 1.00 km/s
The time the shell flies is determined by the y-component, when it reaches the highest point the speed is 0 due to the gravitational acceleration.
0 = 1000 - 9.8 * t
9.8 * t = 1000
t = 102.04 s
After reaching the highest point the shell takes the same time to reach the ground where it was fired, so the total time it flies is 102.04* 2 = 204.08 s
Now you can calculate the distance it moves horizontally while it flies (constant speed)
d = 1.81 km/s * 204.08 s (I used the speed in km/s because the answer needs to be in km)
d = 369.38 km
