Answer:
0.0928J
Explanation:
the pulling force of spring F=-kx
where x is the displacement from equilibrium position.
energy stored:
*** Its fine if you know nothing about calculus. Just apply the equation
where U is the potential energy of the spring***
put x=0.150, 
×
= 0.0928J (corr. to 3 sig. fig.)
A lighted candle produces heat however not as much heat as a heater or the sun would.
Answer:
Graph #2
Explanation:
Notice, on the position time graph, there is a constant rate of change. This means that there is a constant velocity, meaning it's a straight line. The line is decreasing so the velocity will be negative.
The answer - all of the above.
X -rays are applied in many ways and for various purposes in every day life. They are defined as powerful waves of electromagnetic energy. They are able to penetrate most materials both organic and inorganic.
Their ability to penetrate organic material has made them especially useful in medicine where they can penetrate the body and reveal internal structures such as bones and organs.
In the airports, they are used for security purposes to check in luggage bags for prohibited or dangerous items.
In art, they are widely used by authenticators check for types of paper, materials, changes of composition and other clues to help establish authenticity of art pieces.
I would recommend, to include the scientific part of Newton's Laws of motion, with an example. Also, state how all three laws play a part in the activity. It seems like you just did the realistic part of it, swimming, now include how it happens with correct vocabulary. Good Luck!
