HELPPP IM DESPERATE

a coil has n turns enclosing an area of a. in a physics laboratory experiment, the coil is rotated during the time interval δt f

Mrac [35]

The correct answer for the question that is being presented above is this one:

Phi = BAsin(theta)
<span>1. Phi(i) = BA </span>
<span>2. Phi(f) = 0 </span>
3. EMF = N(phi(i)-phi(f))/deltat

Here are the follow-up questions:

<span>1. What is the total magnitude Phi_initial of the magnetic flux through the coil before it is rotated? </span>
<span>2. What is the magnitude Phi_final of the total magnetic flux through the coil after it is rotated? </span>
<span>3. What is the magnitude of the average emf induced in the coil?</span>

Review. A light spring of force constant 3.85 N/m is compressed by 8.00 cm and held between a 0.250-kg block on the left and a 0

vivado [14]

The spring exerts on each block an outward force of magnitude

$\left|\mathrm{F}_{\mathrm{s}}\right|=\mathrm{kx}=(3.85 \mathrm{~N} / \mathrm{m})(0.08 \mathrm{~m})=0.308 \mathrm{~N}$

$Take the $+\mathrm{x}$ direction to the right. For the light block on the left, the vertical forces are given by$

$\mathrm{F}_{\mathrm{g}}=\mathrm{mg}=(0.250 \mathrm{~kg})\left(9.80 \mathrm{~m} / \mathrm{s}^2\right)=2.45 \mathrm{~N}$$ \\and \ $\sum \mathrm{F}_{\mathrm{y}}=0$so $\mathrm{n}-2.45 \mathrm{~N}=0 \rightarrow \mathrm{n}=2.45 \mathrm{~N}$ \\Similarly, for the heavier block,$

$\mathrm{n}=\mathrm{F}_{\mathrm{g}}=(0.500 \mathrm{~kg})\left(9.80 \mathrm{~m} / \mathrm{s}^2\right)=4.90 \mathrm{~N}$

$\begin{aligned}&\sum F_x=m a_x:-0.308 \mathrm{~N}=(0.250 \mathrm{~kg}) \mathrm{a} \\&\mathrm{a}=-1.23 \mathrm{~m} / \mathrm{s}^2\end{aligned}$$\\\\$$ For the heavier block, \\$$+0.308 \mathrm{~N}=(0.500 \mathrm{~kg}) \mathrm{a}$$$$\mathrm{a}=0.616 \mathrm{~m} / \mathrm{s}^2$

<h3>What is kinetic energy?</h3>

The kinetic energy is the energy that it possesses due to its motion.

To accelerate an object, we need to apply force. To apply force, we have to be compelled to do work. When work is done on an object, energy is exchanged, and the object moves with a unused steady speed. We call the energy that's exchanged kinetic energy, and it depends on the mass and speed accomplished.

Kinetic energy is a scalar quantity, it is entirely described by magnitude

What is matter using the word mass, atom, and.molecular <br> Please answer quick please thank you

Andrew [12]

Matter is made of single particles called atoms and is any substance that has either mass or volume. Matter can exist in three states, either as a solid, a liquid or a gas. When two or more atoms combine, they form molecules and Atoms are made up of three sub-atomic protons called protons, neutrons and electrons. The protons and neutrons are densely packed together in the nucleus

5. Bill is swimming and drops his swim goggles in the pool. He looks from above the top of the water to see where they fell and

Alexus [3.1K]

The interaction of light that distorted the image of where Bill's goggles appear to be is Refraction.

<h3>What happens to the speed of light when it hits water in a swimming pool?</h3>

The light slows down when it passes from the less dense air into the water, this slow down of the ray of light which causes the ray of light to change direction and then the changes the speed of the light that causes refraction.

The swimming pool appears shallow than it appear to be because the rays of light coming from the bottom of the swimming pool that is refracted by the water making the height of the swimming pool to be above the actual swimming pool bed and there by misleading the observer(Bill).
