the minimum value of torque is 101.7 N-m.
Explanation:
Given that,
Mass of bundle of shingles, m = 30 kg
Upward acceleration of the shingles,
The radius of the motor of the pulley, r = 0.3 m
Let T is the tension acting on the shingles when it is lifted up. It can be calculated as :
T-mg=ma
T=m(g+a)
Let is the minimum torque that the motor must be able to provide. It is given by :
the minimum value of torque is
Answer:
Explanation:
m = Mass of ice = 200 g
= Temperature change of water =
c = Specific heat capacity of water = 4200 J/kg °C
= Specific latent heat of fusion = 340 kJ/kg
= Specific latent heat of vaporisation = 2260 kJ/kg
Heat required to convert ice to water =
Heat required to raise the temperature of water to boiling point =
Heat required to convert water to steam =
Total heat required
Heat required to convert the given amount of ice to steam at the required temperature is .
