Windmill technology can generate power using a renewable source of energy that does not pollute the environment. By generating a surplus of energy, individuals can sell it to the power company which can replace the energy generated by burning fossil fuels.
The third alternative.
Answer:
Explanation:
Given
Mass of ice 
mass of water 
Initial Temperature of water 
Let T be the Final Temperature of mixture
Latent heat of Fusion 
heat required to melt ice completely is
Heat released by water is taken by ice thus
A compound is made up of two or more of atoms that are bonded together with each other via a chemical bonding. It is possible to break the compounds into separate smaller components by the process of chemical reaction. One very simple example of compound is water as it is made of two atoms of hydrogen and one atom of oxygen. Whenever atoms are joined together to create a compound, the atoms definitely loose their individual atomic properties. Other very commonly found compound is carbon dioxide. It is made up of one atom of carbon and two atoms of oxygen.
Answer:
B
Explanation:
Transformation of energy involves conversion of energy from one form to another for example our movement around involves the conversion of chemical energy stored in the food we eat to other forms of energy such as kinetic energy for the movement, electrical energy in the neurons for impulses and others
The ball posses gravitational potential energy since it is held at a displacement to the ground ( zero point) and when released, the gravitational potential energy is converted to kinetic energy which leads to the fall of the ball until it is at zero displacement to the earth. The board likewise when bent to its maximum extent stored elastic potential energy as a result of the partial displacement of its constituent particle provided it is not stretch beyond its elastic limit which can lead to deformation of the board and the elastic potential energy lost.
Answer:
7229 N
Explanation:
The gravitational force between the Death Star and the Millenium Falcon is given by:
where
is the gravitational constant
is the mass of the Death Star
is the mass of the Millennium Falcon
is the radius of the Death Star
Substituting numbers into the equation, we find the force
