During the spin cycle of your clothes washer, the tub rotates at a steady angular velocity of 33.5 rad/s. Find the angular displacement of the tub during a spin of 90.7 s, expressed both in radians and in revolutions.

3038.45 in radians and

483.52 in revolutions

The angular velocity (ω) of a rotating body is the time (t) rate of change in the angular displacement (θ) of the body. i.e

ω = θ / t;          (i)

The following are given in the question;

ω = 33.5rad/s

t = 90.7s

Substitute these values into equation (i) as follows;

33.5 = θ / 90.7

Solve for θ;

θ = 33.5 x 90.7

θ = 3038.45 rad

Convert the value of the displacement from radians (rad) to revolutions (rev)

Remember that;

2π rads = 1 rev

=> 3038.45 rads = (3038.45 / 2π) rev

Take π = 3.142

=> 3038.45 rads = (3038.45 / (2 x 3.142)) rev

=> 3038.45 rads = 483.52 revs

Therefore the angular displacement of the tub during a spin of 90.7s is 3038.45 in radians and 483.52 in revolutions

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
