The two competing forces that keeps earth orbiting the sun is gravity and inertia
Yhuihoifjhh <span>F = Gm1m2 / r^2
if the masses are doubled then the force is increased by a factor of 4
if the distance is doubled the force is decreased by a factor of 1/ 2^2
the net result is no change in force</span>
A wave transfers energy from the source outward in the
direction of wave motion.
To add, <span>in physics, a </span>wave<span> is an oscillation accompanied by a transfer of
energy that travels through a medium (space or mass). Frequency refers
to the addition of time.</span>
MA = (Effort Distance)/(Effort Resistance) = L/H
L = MA * H = 5 * 8" = 40"
