Explanation:
Answer: 2.4 watts
Explanation:
Work done by horse = 910J
Time = 380 seconds
Power output of the horse = ?
Recall that power is the rate of doing work. Thus, power is workdone divided by time taken.
i.e Power = (work/time)
Power = 910J/380seconds
Power = 2.395 watts (rounded to two significant figures as 2.4 watts)
Thus, the power output of the horse is 2.4 watts
Answer:
S = 2461.53 [kJ]
Explanation:
The change in entropy in a process such as melting can be calculated by means of the following expression.
where:
S = entropy [kJ]
H = fusion heat = 3.36*10¹ [J/kg]
m = mass = 0.02 [kg]
T = temperature in kelvin = 273 [K]
