Answer:
a = v^2 / R centripetal acceleration
R = v^2 / a a at the surface of earth is 9.8 m/s^2
R = (90 m/s)^2 / 9.8 m/s^2 = 827 m
Answer: it's B
Explanation:
991.67 miles per day
Since it travels 2975 miles per day, distance traveled in a day =2975/3=991.67 miles
45° × π/180 = 0,7854 rad
ω = θ /t
ω = 0.7854 / 0.75 = 1.0472 rad/s
I think is B. sound, nuclear, electrical
but if I wrong then I am so sorry
the answer would be 2.9x10^-18 J
