Hello there.
Which of these statements best describes the role of creativity in science?
It helps scientists create theories which are universal.
Answer:
(a) 0.525
(b) 1750J
Explanation:
Coefficient of Performance (COP) = Q2/(Q1 - Q2)
Q1 = heat rejected to the surrounding = 1750J
Q2 = heat absorbed in the environment = 585K
COP = 585/(1700 - 585) = 585/1115 = 0.525
(b). Heat expelled to the surrounding (room) = 1750J
Answer:
0.13 seconds
Explanation:
Since 1 Km = 0.621 miles
3.84 x 105 km = 3.84 x 105 × 0.621 = 23846.4 miles
Speed = distance/time
time= distance/speed
Time= 23846.4/186,000
Time= 0.13 seconds
