Answer: i think its c but i am not sure tho but i think its she could replace the 6 v battery with a 12 v battery
Explanation: cause a 12 v is stronger than a 6 v battery
Answer:
a)1396.52 N
b)1396.52 N
c)
d)
Explanation:
The force experienced by the satelite is giveb by
m_{satellite}= 445 Kg
m_{earth}= 6×10^24 Kg
radius r= 1.77Re= 1.77×6.38×10^6 m
now putting values we get
⇒F= 1396.52 N
now,
also,
Displacement is d
Vf² = Vi² + 2 g d
(-20²) = (+10²) + 2 (-9.8) d
-19.6 d = 300
d = -15.3 m
negative means lower
time is t
d = Vi t + 1/2 g t²
-15.3 = 10 t + (-4.9) t²
4.9 t² - 10 t -15.3 = 0
t = 3.06 s
I am not sure if this is the answer you are looking for but a earthquake occurs when the plates shift.
Hope this helped.
Answer:
In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5% more at the poles than at the Equator.
