Question:

Which of the following is not true of the wind?

A) It is initiated by the pressure gradient force.

B) It blows from regions of high pressure to regions of low pressure.

C) The direction of flow can be affected by the rotation of the Earth.

D) Air blows from regions of hotter air to regions of colder air.

E) Winds are named based on the direction from which they blow.

The given statement "Air blows from regions of hotter air to regions of colder air" is not true of the wind.

Option D

Explanation:

The wind is the form of energy transfer in a wave when there is a change in the pressure gradient force. So, the air molecules in the atmosphere will be exhibiting a different gradient force leading to their movement as the wind. As the air molecules present in higher density at high pressure will tend to release its energy by spreading themselves leading to low pressure.

And thus, the wind will be blowing from regions of high pressure to regions of low pressure. Mostly the winds are named based on the direction of their flow or blow and their direction gets affected by the rotation of the earth. So the only option that is air blows from regions of hotter air to regions of colder air is not true for wind.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
