Answer: 656 rad/s
Explanation:
Angular frequency is also called radial circular frequency. It measures angular displacement per unit time. It's unit is rad/s. It is also greater than the regular frequency by a factor of 2π. Hence, angular frequency, ω = 2πf
If 1 revolution(20 hole) = 20 cycle per revolution.
Then, 2087.8(cycle) = x revolution
X revolution = 2087.8/20)
X revolution = 104.39 revolution
ω = 2πf
ω = 2 * π * 104.39
ω = 655.98676
ω ~ 656 rad/s
C it is transformed into chemical energy
Newton's first law actually states that a force isn't needed to keep an object moving, so no.
The answer is A. With modern technology we have found that climate is much more than just the average temperature
Answer:
1.1215 h
Explanation:
Δt=Δt_o/√(1-u^2/c^2)
(Δt° is the proper time in the rest frame,
Δt is the time intent measured in the second frame of reference u is the speed of the second frame with respect to the rest frame c is the speed of light )
a) the proper time is the time on spacecraft (rest frame);
Δt = 365 days = 8760 h
Δt=Δt_o/√(1-u^2/c^2)= 8761.1215 h
the difference = 8761.1215 h — 8760 h = 1.1215 h
