valina [46]

The centripetal force on the ball is 140.9 N; option A

<h3>What is the centripetal force on the ball?</h3>

The centripetal force on the ball is given by the formula below:

F = mv²/r

where;

m is mass
v is linear velocity
r is radius

The linear velocity, v = wr

v = 5 * 2π/4.4 * 1.4 = 9.93 m/s

F = 10² * 2/1.4 = 140.9 N

In conclusion, the centripetal force is derived from the mass, velocity and radius of the path.

a steam engine works on its vicinity and 285 k heat is released with the help of 225 degree centigrade energy absorbed to the sy

Studentka2010 [4]

The efficiency of the steam engine is 78.9%.

<h3>What is the efficiency of a machine?</h3>

The efficiency of a machine is a measure of the useful work done by the machine as against the work input into the machine.

Efficiency of a machine = work output/work input × 100%

Work output of the steam engine = 225 K

Work input of the steam engine = 285 K

The efficiency of the machine = 225/275 × 100% = 78.9%

Therefore, the efficiency of the steam engine is 78.9%.
