The gravitational potential energy (G.P.E) of the ceiling fan is 712.95 Joules.

<u>Given the following data:</u>

  • Mass of ceiling fan = 7.5 kg
  • Height = 0.7 m

<u>Scientific data:</u>

  • Acceleration due to gravity = 9.8 m/s^2

To calculate the gravitational potential energy (G.P.E) of the ceiling fan:

<h3>What is gravitational potential energy?</h3>

Gravitational potential energy (G.P.E) can be defined as the energy that is possessed by an object or body due to its position (height) above planet Earth.

Mathematically, gravitational potential energy (G.P.E) is given by this formula;

GPE = mgh

<u>Where:</u>

  • G.P.E is the gravitational potential energy.
  • m is the mass of an object.
  • g is the acceleration due to gravity.
  • h is the height of an object.

Substituting the given parameters into the formula, we have;

GPE = 7.5 \times 9.8 \times 9.7

GPE = 712.95 Joules.

Which statement best describes how energy transfer within earths atmosphere 10 affect a weather condition? A)during radiation ob
Pie

Answer: D

Explanation: During convection, heat is being transferred between substances in direct contact with each other by electro magnetic waves.

Using the molten rock to explain the convection in the earth relative to how if affects the weather condition. Here, the rock is in a molten state, rising up from the bottom of the mantle after becoming hotter and less dense from the heat of the earth's core. As the rock loses heat into the earth's crust, it become cooler and more dense,sinking back to the core. These constantly circulating cells of hotter and cooler molten rock help to heat the earth's surface.

alexdok [17]

Answer:

Unit Cell

Explanation:

  • A unit cell is the smallest fundamental particle of a crystal structure that represents the structure of a crystal.
  • Long-range, three-dimensional repetitiveness of this unit cell forms a crystal. A unit cell is composed of ions or atoms in a particular arrangement forming a well-defined structure.
  • Crystal have a sharp melting and boiling point and when cut using a tool, they give a sharp edge on the pieces.

Average human body temperature is 98.6F. What is the equivalent in degrees Celsius?
nikdorinn [45]

Answer:

37 degrees Celsius

Explanation:

From the question

F =98.6F

C = 5/9 x (F-32)

C = 5/9 x (98.6 - 32)

= 5/9 x 66.6

= 333/9

= 37 degrees Celsius
