Answer:

Angular displacement will be 4.48 rad

So option (a) will be correct option

Explanation:

We have given initial angular acceleration \omega _i=0.5rad/sec

Angular acceleration \alpha =0.04rad/sec^2

Time t = 7 sec

We have to find the angular displacement

We know that angular displacement is given by

\Theta =\omega _it+\frac{1}{2}\alpha t^2=0.5\times 7+\frac{1}{2}\times 0.04\times 7^2=4.48rad

So option (a) will be correct option

How are ice liquid water and water vapor different from each other?
olga_2 [115]
The molecules of ice stick together in the process of cohesion. They are tightly packed so there isn't much room to move. Liquid water is a looser hold. The molecules can go past one another, and they will take the shape of whatever container they occupy. Water vapor is loosely contained, and it will will fill whatever container it is kept in, and it will take its shape, too.
