A block of mass 15.0 kg is suspended from a heavy metal ring by a vertical wire. The ring is suspended from the ceiling by two wires. The left wire has a tension of 283 N and makes an angle
of a = 31.0° with the ceiling. The right wire makes an angle of b = 68.0° with the ceiling. Find the
mass of the ring.

1/0.14nm = 10^10/1.4 a lot

this could be newton#'s law of cooling. the cooling curve is exponential

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
