a) Calculate the amount of force that the moon exerts on 1kg of earth at earths center.
b) Calculate amount of force that the moon exerts on 1kg of water on the side of the earth nearest to the moon.
c) Calculate amount of force the moon exerts on 1kg of water on the side of earth farthest from the moon.
Please help, wasnt here also for these problems.

Best ResponseYou've already chosen the best response.0Oh so G times the mass of the moon divided by distance, but the thing is it doesnt really give you the distance

Best ResponseYou've already chosen the best response.0Well, G times mass of the moon times mass of the 1 kg of earth divided by the distance from the center of the earth to the center of the moon (you have to look up those distances)

Best ResponseYou've already chosen the best response.0Ohhhh ok, but how would you find the distance when it asks: "Calculate... on the side of the earth nearest to the moon" and also "...farthest to the moon" for the second and third question it doesnt give a specific distance.

Best ResponseYou've already chosen the best response.0From the center of the earth is radius of the earth + distance between earth and moon + radius of the moondw:1432878133979:dw

Best ResponseYou've already chosen the best response.0I know the pic is bad, but does that make sense?

Best ResponseYou've already chosen the best response.0Well yea, the pic is good btw, but anyways, the only thing that ill really need to do then is to just plug in the numbers, right? Nothing else to it? And one more thing, when it says "on the side of earth" how would you calculate where that distance would be too?

Best ResponseYou've already chosen the best response.0Oh good. :) That's it, just make sure that your units are consistent (kg for mass and m for distance.

Best ResponseYou've already chosen the best response.0When it is on the side of the earth closer to the moon, that would not include the radius of the earth.

Best ResponseYou've already chosen the best response.0And the side of the earth farther from the moon would be twice the radius of the earth (or the diameter)

Best ResponseYou've already chosen the best response.0Oh yesss ok I get it now, thanks so much! You saved me half the assignment that i didnt know how it worked, so thank you, lol I might need more help with other questions too cause I really dont understand it, but only if your up for it.
