Ok the velocity of an object in free fall is given by the equation :
v=v0-gt, where v0 is the original velocity, g is the gravitational constant (9.8 m/s^2) and t is the time.
so, we substitute values into this equation. v=35.8-9.8*2.5; v=11.3 m/s
The period is 2 seconds. The frequency is 0.5 Hz.
Answer:
The wind would mostly STOP BLOWING
Explanation:Wind is caused by a pressure gradient (two different surface air pressures). ... This would result in winds. If the atmosphere suddenly became mixed 100% so that humidity was equal all around the Earth, with equal temperature then there would be no change in pressure and no wind.
hope this helped:)

Complete Question
The complete question is shown on the first uploaded image
Answer:
The pressure difference of the first bubble is 
The pressure difference of the second bubble is 
The pressure difference on the second bubble is higher than that of the first bubble so when the valve is opened pressure from second bubble will cause air to flow toward the first bubble making is bigger
Explanation:
From the question we are told that
The radius of the first bubble is 
The radius of the second bubble is 
The surface tension of the soap solution is 
Generally according to the Laplace's Law for a spherical membrane the pressure difference is mathematically represented as

Now the pressure difference for the first bubble is mathematically evaluated as

substituting values


Now the pressure difference for the second bubble is mathematically evaluated as
