Administrator answers:

You might want to double check your pc specs. I’ve never seen a i3 mother board with no pcie slot asms never even heard of a100w power supply.

What is the magnitude of the net gravitational force on the mass at the origin due to the other two masses?

Three identical masses of 640 kg each are placed on the x axis. One mass is at x1 = -10.0 cm, one is at the origin, and one is at x2 = 36.0 cm. Take the gravitational constant to be G = 6.67×10?11 N * m^2/kg^2.

Can someone solve for this and show me how they arrived at the answer? Thank you.

Administrator answers:

Gravitational force = G*M*m/r^2

Since the mass on the left is closer to the center mass, the net force will point towards the left.
Since all the masses are the same I will call it m and in the above equation we have M = m.

G = 6.67×10^(-11) M m^2 / kg^2
m = 640 kg
x1 = 10 cm = 0.1 m
x2 = 60 cm = 0.6 m

Fnet = G*m^2[1/x1^2 - 1/x2^2] = G*m^2[100 - 100/36] = G*m^2[3500/36]
Fnet = 1.891×10^(-3) N and it is directed towards the mass on the left

What is the cheapest way to renovate a kitchen?

We are have recently made an offer to purchase a property with two 3 x1 duplex’s already erected on the property requiring quite a bit of renovation. We have had a look around and it is all so confusing & expensive. Can anyone please give us some advise on how we can renovate the Kitchen’s in both property’s at a reasonable price?

IKEA kitchen cabinets are high quality and very inexpensive. You can customize to your heart’s content!
