Answer:
Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not. While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

0.975 is correct, to get the answer you divide the length value by 10.
Answer:
Increase.
Explanation:
The force between two charges is given by :
Where
k is electrostatic constant
d is the distance between two charges
The force is inversely proportional to the distance between charges. It means when the distance between two charges decreases, the electric force will increase. Hence, the correct option is (c) "increase".
The answer to this question would be the Law of conservation of energy.
In every chemical reaction, 10 atoms of reacted will make 10 atoms as result. The number of atoms produced will be same as the number of ingredients. This will prove that the energy is <span>can neither be created nor destroyed; The energy is just changed into a different shape.</span>
Answer:
A spring whose spring constant is 200 lbf/in has an initial force of 100 lbf acting on it. Determine the work, in Btu, required to compress it another 1 inch.
Step 1 of 4
The force at any point during the deflection of the spring is given by,
where is the initial force
and x is the deflection as measured from the point where the initial force occurred.
The work required to compress the spring is
Therefore work required to compress the spring is
The work required to compress the spring in Btu is calculated by
Where 1Btu =778
The work required to compress the spring,
