Formula for potential energy is V=mgh, where m is mass in KG, g is earth acceleration (10 m/s^2), and h its height in meters. We know mass, acceleration is constant and also known, we know height also. Lets substitute
V=75*10*300=225000[J]=225[kJ] - its the answer

How can a driver steer a car traveling at constant speed so that the magnitude of the acceleration remains constant. (Assume tha
ratelena [41]

<h2>Circular path i.e 1</h2>

Explanation:

If the driver steer into circular path , the acceleration of car will be

acceleration = velocity²/radius  of circle

Because the velocity and radius of circle are both constant at all points . Thus the acceleration will also remain constant .

In case 3 and 4 , the radius of path changes . Because velocity is constant . Therefore the acceleration will not remain constant

List atleast to conditions that could cause the pressure inside a sealed container of gas to increase
hjlf
There are exactly three ways that could happen:

1).  The container was heated, and the gas inside it got warmer.

2).  Some part inside the container moved somehow, and made
      the inside volume smaller, so the gas got scrunched into a
      smaller space.

3).  Somebody pumped some more gas into the container, so
      a greater amount of gas had to live in the same space.

Why is it important to know the location of active and inactive faults in our country?
Andrew [12]

Answer:

I hope this helps.

Explanation:

It's important to know the location of an active fault in order to determine the magnitude of the expected earthquake. There is a chance than an inactive fault can become active again. It's important that we take the locations into account in order to be prepared and ready for if it occurs.
