Answer:
Explanation:
As we know that diameter of hand crank is given as
Also the diameter of the shaft on which the rope is wound is given as
now we know that both are moving with same angular speed
so we will have
so we will have
<h2>
Heat released in this process is 3516.7 J</h2>
Explanation:
A calorimeter has a heat capacity of 1265 J/°C
Heat capacity of calorimeter = 1265 J/°C
A reaction causes the temperature of the calorimeter to change from 22.34°C to 25.12°C
Change in temperature = 25.12 - 22.34 = 2.78°C
Heat released = Heat capacity of calorimeter x Change in temperature
Heat released = 1265 x 2.78 = 3516.7 J
Heat released in this process is 3516.7 J
Calculated Speed for the entire trip can be called as "Average Speed".
