(1) The pendulum will have maximum velocity at the lowest point and it will be the most difficult point to stop.
(2) Velocity at maximum height is zero and it will be the easiest point to stop the pendulum.
(3) The total mechanical energy of the pendulum would be the same at all point.
<h3>Point of maximum velocity of the pendulum</h3>
A pendulum has maximum kinetic energy at the lowest point. The kinetic energy is given as;
K.E = ¹/₂mv²
The pendulum will have maximum velocity due to maximum kinetic energy at the lowest point and it will be the most difficult point to stop.
<h3>Point of maximum height of the pendulum</h3>
A pendulum has maximum potential energy at the highest point. The potential energy is given as;
P.E = mgh
Velocity at maximum height is zero and it will be the easiest point to stop the pendulum.
<h3>Conservation of energy</h3>
In absence of friction, the total mechanical energy will be conserved. Thus, the total mechanical energy of the pendulum would be the same at all point.

To solve this, you subtract the initial volume from the final volume. So, 29.5 mL minus 25.0 mL is 4.5 mL. Technically, at this point you need to say 4.50 mL, because of sig figs. The volume of the stone will not be in mL, because the stone is not a liquid or a gas, so you must convert it to cm3. So, your answer is (a), 4.50 cm3.

Well I figured out at his current pace, he would finish the 1100 remaining meters in 200 seconds. However, he needs to complete it in 180 seconds. I'm not sure how to find out how long he has to accelerate at 0.20 m/s/s to complete it in 180 seconds.
Answer:
A. during the day or night and in any weather conditions.
Explanation:
Ground-based radio telescopes can be used to collect data from distant objects in space during the day or night in any weather condition.
They do not depend or are they affected by weather and they pass well through them.
- Telescopes are devices used to obtain information about distant bodies usually astronomical in nature.
- Optical telescopes use the visible range of light and they are overwhelmed by the sun during the day.
- Bad weather conditions can also diminish the reception of light.
- They work best at night.
- Radio telescopes uses electromagnetic radiations and can work at any time and during any weather.
