There is still air inside of a house, which is pushing the roof upwards, so the forces are equal and the roof is not crushed.

Heat lost = (75000)(3.77)(3) = 848250 J = heat gained by water

848250 = 400000(4.814)(T)
T = 0.507 C
4 + 0.507 = 4.507 C

I have a picture of the question I need help with,
eduard

Given:

The initial velocity of the object, v=30 m/s

a_t=0

a_c≠0

The time period is Δt.

To find:

The right conclusion among the given choices.

Explanation:

a_t represents the tangential accleration on the object and a_c represents the centripetal acceleration on the object.

The centripetal acceleration is the acceleration that keeps the object in its circular path. The centripetal force only changes the direction of the velocity and not the magnitude.

Thus the magnitude of the velocity of the object remains the same after a time interval of Δt. But the direction of the velocity of the object will be changed and will be unknown after Δt seconds.

Final answer:

Thus the object will be traveling at 30 m/s in some unknown direction.

Therefore, the correct answer is option a.
