Answer:
from the cup to the hand
Explanation:
Heat present one body transfer to the other less heat body or cold body through physical contact is called conduction. The temperature of the cup is higher which is 90°C whereas the temperature of the hand is 36°C so difference between temperature of both bodies causes conduction of heat energy from hotter body to cold body so we can conclude that the heat energy will transfer from the cup to the hand.
Answer:
Work done = 838470 Joules.
Explanation:
Given the following data;
Power = 19 hp
Time = 1 minute to seconds = 60 seconds.
Next, we would convert the unit of power in "hp" to "Watt."
1 Watt = 0.00135962 horsepower
x Watt = 19 horsepower
Cross-multiplying, we have;
19 = 0.00135962x
x = 19/0.00135962
x = 13974.5 Watts.
Now, to find the work done in moving the mower;
Work done = power * time
Substituting into the formula, we have;
Work done = 13974.5 * 60
Work done = 838470 Joules.
