Answer:

The change is momentum is given by ∆p=p(inital) - p(final) =4-2=2 kg.m/s

Explanation:

momentum is the product of mass and velocity (speed)

So it's initial momentum would be:

p=mv=(1)(4)=4 kg.m/s

It's final momentum is given by:

p=mv=(1)(2)=2 kg.m/s

Explanation:

The given data is as follows.

Angular velocity ( $\omega$ ) = 2.23 rps

Distance from the center (R) = 0.379 m

First, we will convert revolutions per second into radian per second as follows.

= 2.23 revolutions per second

= $2.23 \times 2 \times 3.14 rad/s$

= 14.01 rad/s

Now, tangential speed will be calculated as follows.

Tangential speed, v = $R \times \omega$

= 0.379 x 14.01

= 5.31 m/s

Thus, we can conclude that the tack's tangential speed is 5.31 m/s.

juin [17]

Answer : The correct option is, (C) cannot be reversed

Explanation :

The thermodynamic process is a process in which the thermal or heat energy is converted into mechanical energy and some amount of energy goes into surroundings. That means, the total amount of energy is not converted into mechanical energy.

Or we can say that the energy can not be created or destroyed, it can only change or transfer from one state to another state.

The thermodynamic process is not a reversible process that means it is an irreversible process.

Hence, the correct option is, (C) cannot be reversed
