Answer:
291 K is the answer
Explanation:
to get Kelvin from Celsius use the following
Kelvin = Celsius +273
= 18 +273
= 291
Answer:

Explanation:
Given that,
Mass of a brick, m = 3.1 kg
The dimensions of the brick 225 m x 112 m x 75 m
We need to find the maximum pressure created by the brick. We know that, the force acting per unit area is called pressure exerted. It is given by the formula as follows :

F = mg
A = area with minimum dimensions i.e. 112 m x 75 m
Pressure is maximum when the area is least.
So,

So, the maximum pressure created by brick is
.
Answer:
The answer is
. Let's learn why.
Explanation:
Newton's law of universal gravitation says;

Here G is a universal gravitational <u>constant</u> and is measured experimentally.
Sun's gravitational pull on mercury is:

Therefore 
Sun's gravitational pull on Earth is:

Therefore 
As a result;

Answer:
A wind turbine captures the wind, which then produces a renewable energy source. The wind makes the rotor spin; as the rotor spins, the movement of the blades drives a generator that creates energy. The motion of the blades turning is kinetic energy. It is this power that we convert into electricity.
