You pull downward with a force of 27.3 N on a rope that passes over a disk-shaped pulley of mass 1.43 kg and radius 0.0792 m. Th
Salsk061 [2.6K]

Answer:

The tension in the left side string = 17.21 N

The tension in the right side string = F = 27.3 N

Explanation:

Given that

F= 27.3 N

M= 1.43 kg ,r= 0.0792 m

Moment of inertia of disk ,I = 0.5 m r²

I = 0.5 x 1.43 x 0.0792² = 0.0044 kg.m²

m= 0.7 kg

Lets take linear acceleration of system is a m/s²

Lets take tension in left side string = T

From Newtons law

T- mg = ma  

T- 0.7 x 10 = 0.7 a  ----------1

(F - T) r = I α      

α = Angular acceleration of disk

a = α  r

(F - T) r = I α  

(F - T) r² = I a  

( 27.3 - T) x 0.0792² = 0.0044 a        --------2

Form equation 1 and 2

a= 1.42 T - 10 m/s²

a = 1.42 ( 27.3 - T)  m/s²

1.42 T - 10 = 38.9 - 1.42 T

T=17.21 N

The tension in the right side string = F = 27.3 N

What percentage of the net income earned in the United States is generated by corporations?
azamat
<span>The correct answer is C. 60. A more precise answer would be around 70, but this is the closest one we have. As a matter of fact, 50% of the net income is made by only 5% of companies, while the remaining US corporations raise the bar to around 70. These 5% are mostly conglomerates that deal in all areas of business, from food to cosmetics to furniture.</span>
