25. a small container of water is placed on a turntable inside a microwave oven, at a radius of 12.0 cm from the center. the turntable rotates steadily, turning one revolution in each 7.25 s. what angle does the water surface make with the horizontal?

Sagot :

The angle that the water surface make with the horizontal is 0.527°.

How to calculate the angles?

The water vapor moves at speed. Therefore,

v = 2πr/T = (2 × π × 0.120)/7.25

= 0.104m/s

Also, the top layer of water deals a downward force if gravity which will be:

= mv²/r = 0.104/0.12 = 0.0901

There, the angle will be:

= tan(0.0901/9.8)

= 0.527°

In this case, the angle that the water surface make with the horizontal is 0.527°.
