Answer:

There are different answers to that, like if you read a passage or something.

Explanation:

These days many people do not get exercise. A lot of jobs are now done indoors and do not require any physical activities. Technology is becoming more advanced and many people prefer using machines to do the heaving lifting.

There are a lot of fast-food restaurants and this is where a lot of people in the US choose to eat. The food is cheap and easy to pick up. This food is convenient for people on the go. The food is not healthy and it causes weight gain.

In the US, many young children find it cool to smoke. Smoking decreases the body's strength and it causes a decrease in physical health, causing people to gain weight.

Everyone has a phone these days, if not some kind of electronic device to chat with people or play games. Over time, playing on electronic devices replaces doing physical activities.

A uniform disk with a mass of 5.0 kg and diameter 30 cm rotates on a frictionless fixed axis through its center and perpendicula

igomit [66]

Answer:

Angular acceleration of the disk will be $\alpha =10.714rad/sec^2$

Explanation:

We have given mass of the disk m = 5 kg

Diameter of the disk d = 30 cm = 0.3 m

So radius $r=\frac{d}{2}=\frac{0.3}{2}=0.15m$

Moment of inertia of disk is given by $I=\frac{1}{2}mr^2=\frac{1}{2}\times 5\times 0.15^2=0.056kgm^2$

Force is given by F=4 N

Torque is given as $\tau =Fr=4\times 0.15=0.6N-m$

We also know that torque is given by $\tau =I\alpha$

$0.6=0.056\times \alpha$

$\alpha =10.714rad/sec^2$
