Answer:

C.) the change of state requires energy.

Explanation:

Whenever there is a change of state, such as a solid to liquid or liquid to gas, heat energy can be added without a temperature change because the change of state requires energy, so the added energy does not increase the temperature.

Suppose you are taking a walk one day when you see a tree branch snap at its base and begin to rotate downward with the break ne
Naya [18.7K]

Answer:

α = 3.27 rad/s²

No

Explanation:

Given that

 L= 3 m

Lets take mass of tree = m kg

The torque to mass m =  m g .L

The mass moment of inertia of tree ,I

I = mL² kg.m²

We know that

τ = I α

 m g .L = mL² .α

α= g/L

Now by putting the value

\alpha =\dfrac{ 9.81}{ 3}\ rad/s^2

α = 3.27 rad/s²

No we can find the mass of the from the above information because angular acceleration is not depend on the mass of tree.

A grandfather clock depends on the period of a pendulum to keep correct time. Suppose a grandfather clock is calibrated correctl
Setler [38]

Answer:

Slow

Explanation:

As we know that the time period of simple pendulum is given by

T = 2\pi \sqrt{\frac{L}{g}}

Where, l be the effective length of the pendulum and g be the acceleration due to gravity

As the length of the pendulum increase, then the tie period of the pendulum will also increase.

It means the clock run slow.
