Explanation:
Answer:
122.76J
Explanation:
Given data
work done= 372 Joules
efficiency= 33%
Required
We want to compute the value of the work that is 33%
= 33/100* 372
= 0.33*372
= 122.76J
Hence 122.76J of work is transferred from the engine to the exhaust
Answer:
Explanation:
Given the following data;
Distance = 46 km
Time = 11 minutes
To find the average speed;
Speed = distance/time
93.64 grams
Explanation:mass of platinum =number of moles x molar mass molar mass = atomic mass of any element ,0.48 ×195.084 = 93.64 grams
