The dryer of a washing machine goes into its spin cycle from rest and gains a speed of 5.0 rev/s in 3.0s. When the lid is opened, the dryer slows down and finally stops in the 7.0s. Compute the angular acceleration during the first 3.0s and the last 7.0s. Through how many revolutions does the dryer turn before coming to stop?
At what temperature do Celsius and Fahrenheit are equivalent in value? Prove your answer.
AU-tube of uniform cross-sectional area, open to the atmosphere, is partially filled with mercury. Water is then poured into both arms. If the equilibrium configuration of the tube is as
shown i*n_{j} with h_{2} = 2.5cr , determine the value of
h_{1}
Ashower head has 10 circular openings, each with radius 2.0 mm. The shower head is connected to a pipe with radius 0.70 cm. if the speed of water in the pipe is 4.0 m/s, what is its
speed as it exits the shower-head openings?
A horizontal pipe 20.0 cm in diameter has a smooth reduction to a pipe 7.00 cm in diameter. If the pressure of the water in the larger pipe is 6.0 x 10 Pa and the pressure in the smaller pipe
s 3.0*10^ 4 Pa , at what rate does water flow through the pipes?
