A 0.11 N m torque is applied to a fan that was initially at rest. The fan has moment of inertia of 0.034 kg m2. Determine the ki
Mars2501 [29]

Answer:

2.72*10-3 Joules

Explanation:

From Newton's second law of motion

F=ma

\tau=I*\alpha

given

\tau= 0.11Nm\\\\I=0.034kgm^2\\\\t= 8s\\\\\alpha=?

\alpha =0.11/0.034\\\\\alpha=3.23 rad/s^2

the angular velocity is

\omega = \alpha/t\\\\\omega =3.23/8\\\\\omega =0.4 rad/s

KE= 1/2*I* \omega^2

KE=1/2*0.034*0.4^2\\\\KE=1/2*0.034*0.16\\\\KE=0.00272\\\\KE=2.72*10^-3J

binoculars: provide a magnified stereoscopic view of distant objects.

streak plate: is a technique which is used to grow bacteria on a growth media surface so that individual bacterial colonies are isolated and sampled.

wind vane: is used to determine wind direction.

ruler: is used for measuring a line.

microscope: is used to magnify the objects which are not visible by naked eyes.

magnifying glass: is used to magnifying tiny objects which are difficult to see yet they are visible.

telescope: use by space scientist to examine astronomical event that may take place in the sky which is too far.

5 examples of neutons 3rd law of motion​
Lemur [1.5K]

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.
