The formula used for finding the tangential speed (speed of something that is moving in a circular path) of an orbiting object is:
V₍t₎ = ωr
V₍t₎ = tangential speed or velocity
ω = angular velocity
r = radius of the circular path
if time taken t is only given then use this formula to calculate the tangential speed:
V₍t₎ = 2πr/t, t is time taken
It protects us from the magnetic/electrical radiation that comes from the sun. High radiation periods coincide with solar storms.
Answer:
Explanation:
the same amount of time in both halves of the circle
Answer:
2.8 seconds
Explanation:
Given:
Δy = 38 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(38 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 2.8 s
