What is the purpose of the spin cycle of a washing machine? Explain in terms of acceleration components

Short Answer

Expert verified

The spin cycle of the washing machine removes the water particles from the clothes.

Step by step solution

01

Concept/Significance of radial acceleration

Points on a rigid body have a centripetal (radial) acceleration(arad) whenever the body is rotating. The expression for the radial acceleration is as follows:

arad=v2r

Here, v is the linear velocity, and is the radius.

02

Determine the purpose of the spin cycle of a washing machine and explain in terms of acceleration components

The main purpose of the spin cycle of the washing machine is to remove the water from the clothes.

The centripetal acceleration of a drum of radius r, rotating with speed v is given by,

a=v2r

This centripetal acceleration is created by the centrifugal force, which removes the water particle on the clothes tangentially outwards through the holes of the drum surface.

A useful and easy-to-remember approximate value for the number of seconds in a year is𝛑×107. Determine the percent error in this approximate value. (There are 365.24 days in one year.)

You take an empty glass jar and push it into a tank of water with the open mouth of the jar downward, so that the air inside the jar is trapped and cannot get out. If you push the jar deeper into the water, does the buoyant force on the jar stay the same? If not, does it increase or decrease? Explain.

Hot Jupiters. In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term “hot Jupiter”). The orbit was just19 the distance of Mercury from our sun, and it takes the planet only3.09days to make one orbit (assumed to be circular). (a) What is the mass of the star? Express your answer in kilograms and as a multiple of our sun’s mass. (b) How fast (in km>s) is this planet moving?

You are on the roof of the physics building, 46.0 mabove the ground (Fig. P2.70). Your physics professor, who is1.80 mtall, is walking alongside the building at a constant speed of1.20 m/s. If you wish to drop an egg on your professor’s head, where should the professor be when you release the egg? Assume that the egg is in free fall.
