Explanation:
Natural length of a spring is 
. The spring is streched by 
. The resultant energy of the spring is 
.
The potential energy of an ideal spring with spring constant 
and elongation 
is given by 
.
So, in the current problem, the natural length of the spring is not required to find the spring constant .
∴ The spring constant of the spring = 
C. Three isotopes of the same element because the number of electrons and protons remain the same but the number of neutrons in the nucleus are different. This means that the isotopes have different masses to each other but the same chemical properties.
Answer:It's how the color mixes together . Red and green both makes a dark color
Explanation:
Answer:
a
Explanation:
heat is energy, energy cannot be made or destroyed but transferred
The force of static friction keeps a stationary object at rest. Once the force of static friction is overcome, the force of kinetic friction is what slows down a moving object.
