(a) The value of the gravitational acceleration is given by:
where
is the gravitational constant
M is the Earth's mass
is the Earth's radius at the pole
If we use the value for g given by the problem, 
, and we rearrange the equation above, we find the value of the Earth's mass:
(b) The value we found for the Earth's mass is 
, and we see that this value is slightly larger than the accepted value of 
.
Answer:I have to say 56
Explanation: because it is going up by 8
The density of the substance is obtained by dividing its mass by its volume. Density is an intensive property which means that its value does not depend on the amount of substance and will always stay the same for same conditions.
d = 84.7 g / 46.7 cm³ = 7.75 g / x cm³
The value of x is approximately 4.27 cm³.
Rain is considered a precipitate. Along with: drizzle, sleet, snow and hail.
hope this helps :)
The ocean tides on earth are caused by both the moon's gravity and the sun's gravity. ... Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
