The spin cycles of a washing machine have two angular speeds, 439 rev/min and 602 rev/min . The internal diameter of the drum is 0.500 m . Part A What is the ratio of the maximum radial force on the laundry for the higher angular speed to that for the lower speed

The ratio of the forces is F2/F1 = 1.86

Explanation:

From Newton's second law applied to circular motion, the total force F acting on a body in circular motion is given by

F = mv²/r

Where

m = mass of the body undergoing circular motion

v = linear velocity = ω×r

ω = angular velocity

r = radius of the circular path through which the force acts

So

F = m(ω×r)²/r = mω²×r

Given 2 angular speeds ω1 = 439re/min = 439×2π/60 rad/s = 46 rad/s and

ω2 = 602rev/min = 602×2π/60 rad/s = 63 rad/s

Required to calculate the ratio F2/F1

The mass m and radius r is the same for both forces, so F is dependent on the angular speed

So F2/F1 = ω2²/ω1² = (ω2/ω1)²

F2/F1 = (63/46)² = 1.86

whichever one it is, it's definitely not one that you included on the list you provided.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
