The moon's mass is 7.34x10-kg and it is 3.8x10m away from earth. Calculate the gravitational force of attraction between earth a
Nana76 [90]
Again I think you did not give the right constants. So I would use the correct constants for mass of moon and distance from earth to moon.

<span>The formula for force of attraction between any two bodies in the universe
F  =  GMm / r^2.      (Newton's Universal law of Gravitation).

G = Universal gravitational constant, G = 6.67 * 10 ^ -11  Nm^2 / kg^2.
M = Mass of Earth. = 5.97 x 10^24 kg.
m = mass of moon = 7.34 x 10^22  kg.
r = distance apart, between centers = in this case it is the distance from Earth to the Moon
   = 3.8 x 10^8 m.

(Sorry I could not assume with the values you gave, they are wrong, and if we use them we would be insulting Physics).


So F = ((6.67 * 10 ^ -11)*(5.97 x 10^24)*(7.34 * 10^22)) / (3.8 x 10^8)^2.
  Punch it all up in your calculator.
 
I used a Casio 991 calculator, it should be one of the best in the world.Really lovely calculator, that has helped me a lot in computations like this. I am thankful for the Calculator.

F = 2.0240 * 10^ 20 N.
So that's our answer.
Hurray!!</span>

Explain how pressure operates within a plant cell to help it keep its shape.
natali 33 [55]
A large organelle called a vacuole fills with water and pushes on the cell wall to give it a rigid shape. The amount of pressure exerted by the vacuole is called "turgor pressure".

Does a tree falling over in a forest make a sound if there is no receptor (human or animal ear) to hear it? In your answer, desc
arsen [322]
It does make sound, just because there are no receptors does not mean that an object does not make sound. For example, whales communicate ona frequency higher then our ears can hear, however, we know that they still make sound. Another example is thunder; If you were far away to see thunder but not hear it, does it make sound? It does. Objects make sound by vibrating, there is no connection to sound and the presence of a receptor.
