Answer:

Explanation:

When a liquid is heated, the particles are given more energy. They start to move faster and further apart. At a certain temperature, the particles break free of one another and the liquid turns to gas. This is the boiling point.

In damped harmonic oscillation, the amplitude of oscillation becomes one third after 2 second. If A0 is initial amplitude of osc
Harman [31]

Answer:

A=\frac{A_0}{\sqrt 3}

Explanation:

Initial amplitude=A_0

We are given that

Amplitude after 2 s=A=\frac{1}{3}A_0

We have to find the amplitude after 1 s.

We know that amplitude at any time t

A=A_0e^{-\alpha t}

Using the formula

\frac{A_0}{3}=A_0e^{-2\alpha}

\frac{1}{3}=e^{-2\alpha}

3=e^{2\alpha}

ln 3=2\alpha

\alpha =\frac{ln 3}{2}=ln\sqrt 3

e^{\alpha}=\sqrt 3}

When t=1 s

A=A_0e^{-\alpha}=\frac{A_0}{\sqrt 3}

A physics student spins a bucket of water over her head in a circular path in order to demonstrate centripetal force. She fills
Ronch [10]

Answer:

The first case requires more force to spin de bucket.

Explanation:

As we know, the centripetal force is directly proportional to the mass, the equation is given by:

F_{c}=ma_{c}

The first case has a quarter more water than the second case, therefore the first case requires more force to spin de bucket.

I hope it helps you!
