Magnitude of displacement means the total displacement. Basically taking your final distance and subtracting it from your initial distance so it would be 14m
The answer is 570 J. The kinetic energy has the formula of 1/2mV². The total work in this process W= 1/2m(V2²-V1²) = 1/2 * 15.0 * (11.5²-7.50²) = 570 J.
Hi there!
We can use the rotational equivalent of Newton's Second Law:
Στ = Net Torque (Nm)
I = Moment of inertia (kgm²)
α = Angular acceleration (rad/sec²)
We can plug in the given values to solve.
By definition, when the speed of the light changes when it passes from a material to another, this is called "Refraction of light". This happens when there is a difference in the index of refraction between both mediums o materials. Therefore, that speed depends of <span>the medium through it passes.
</span>
T<span>he index of refraction</span> is expressed as below:
n=c/v
"n" is <span>the index of refraction.
</span> "c" is <span>is the speed of light.
</span> "<span>v" is the phase velocity of light in the medium.

A prism, a magnifying glass, a microscope, and eyeglasses refract light. Therefore, the correct option is: B) They refract light.
The appropriate response is hydrogen ions. It entirely, the core of a hydrogen particle isolated from its going with an electron. The hydrogen core is comprised of a molecule conveying a unit positive electric charge, called a proton.
I hope the answer will help you.
