In the spin cycle of a washing machine, the tub of radius 0.299 m develops a speed of 652 rpm. What is the maximum linear speed with which water leaves the machine? Answer in units of m/s.

Maximum speed of water that leaves the machine is 20.5 m/s

Explanation:

As we know that the angular frequency of the tub is

f = 652 rpm

so we have

now we have

Now tangential speed is given as

so we will have

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

force tends to be low and long diustance masses are high
