Answer:
18.73 m/s^2
Explanation:
f = 2662 rpm = 2662 / 60 rps
r = 6.725 cm = 0.06725 m
Acceleration, a = r w
a = r x 2 x pi x F
a = 0.06725 × 2 × 3.14 × 2662 / 60
a = 18.73 m/s^2
(89000/102000)×100
=87.25%
(92000/104000)×100
=88.46%
efficiency is (output/input)×100
if u get confused which way input and output should go, remember the smaller value is always output and it's above in the fraction, then only it's possible to get a efficiency lower than 100.
The best method to separates mixture of salt and water is evaporation. Take a small sample of mixture in a china dish. Heat it till all water evaporate. The residual remain is salt. Josh should use this method to separate salt from water.
