Answer:
P.E = 980 J
Explanation:
Given,
The mass of the rock, m = 1 Kg
The height of the rock from the ground, h = 100 m
The acceleration due to gravity, a = 9.8 m/s²
The gravitational potential energy of the stone is given by the formula
P.E = mgh joules
Substituting the given values in the above equation,
P.E = 1 x 100 x 9.8
= 980 J
Hence, the gravitational potential energy of the stone is, P.E = 980 J
An image that a concave mirror can make is that it <span>can form a real image that is projected out in front of the mirror. </span>A concave mirror<span> is a mirror that is curved inward in the middle. Using the mirror equation, you can deal with concave mirrors. It's like you're looking into a cave when try to look in a concave mirror.</span>

In the balanced nuclear reaction of uranium 235, we have thorium 231, helium atom and energy released at the right of the equation
<h3>
Balanced nuclear reaction of Uranium</h3>
The balanced nuclear reaction of uranium is determined as follows;
Thus, in the balanced nuclear reaction of uranium 235, we have thorium 231, helium atom and energy released at the right of the equation while uranium 235 is on the left hand side of the nuclear reaction equation.

<h2>Answer: Sedimentary rocks
</h2>
Sedimentary rocks are formed from sediments and deposits of particles of various types, forms and sizes that are transported by air, wind or water, and then subjected to chemical processes to become rocks.
These types of rocks are usually found in the form of layers or strata in places where sediment accumulates due to the erosion of other materials, for example on the banks of rivers, in valleys, lakes (and any other type of body of water).
