Answer:
magnitude of gravitational force between the Earth and the Sun at B is greater than that at A
Explanation:
Formula of gravitational force:
F = GMm/r^2
(r is the distance between 2 objects)
We see that r(B) < r(A) since at B, the Earth is closer to the Sun than at A
According to the Formula, the smaller r is, the greater F is
So, F(B) > F(A)
A-11 polar easterlies
b-8 winds blowing between the equator and 30° N and south
c-10
d-9
Answer:
539.5°
Explanation:
33.3 revolutions per minute
1 revolution = 360°
1 minute = 60 seconds
hence
33.3 revs ----> 1 minute = 60 seconds
X revs -----------> 2.70 seconds
X = (33.3 x 2.7)÷60 = 1.4985 revolutions in 2.70 seconds
1.4985 revolutions = 1.4985 x 360 = 539.46
which is approximately 539.5°
F = ma
Acceleration in this case is acceleration due to gravity so
a = 9.8 m/s^2
and mass = 0.57kg
So..
F = (0.57)(9.8)
F = 5.586 or 5.56 N
It causes the global pattern of wind and precipitation (such as rain, snow, or hail).
