Answer:

F = - K X

X =  -F / K = M g / K = 9.8 * 2.3 / 735 = .03 m = 3 cm

W = 1/2 K X^2

W = 1/2 * 735 N/m * .065^2 m^2 = 1.55 Joules

Static charges can be applied to neutral objects by friction, induction or conduction. What do all of these methods utilize to c
kvv77 [185]

Answer:

B) electrons

Explanation:

When charge is transferred by friction, induction or conduction, the charge carriers are the electrons.

In fact, protons and neutrons are found within the nucleus of the atoms, so they are tightly bound and they cannot be easily gained/given off. On the contrary, electrons are found in the electron clouds around the nucleus, so atoms can more easily gain/lose electrons, which become free and can be passed by an object to another.

The three methods of charging are:

- Friction: by rubbing two objects together, electrons may be transferred from one to another

- Induction: by moving a charged object closer to a neutral object, opposite charges in the neutral object migrate towards the opposite ends of the object, and if the object is connected to the ground, the charges of one polarity leave the object, leaving the object charged

- Conduction: by putting a charged object in contact with a neutral object, electrons can be transferred from the charged object to the neutral one

aalyn [17]

Answer:

<em>The wave will be travelling in the y-axis</em>

Explanation:

An e-m wave has a spatially varying electric field that is always associated with a magnetic field that changes over time and vice versa. The electric field and the magnetic field oscillates perpendicularly to each other, and together form a wave that travels in a perpendicular direction to the magnetic and the electric field in space. The movement of the e-m wave through space is usually away from the source where it is generated. So, if the electric field travels in the z-axis, and the magnetic field travels through along the x-axis, then the e-m wave generated will travel in the y-axis direction.

Hazards of earthquakes on land and and underwater! (20 points)
elena-s [515]

If the earthquake is on land it would cause total devastation, building will fall ( depending on hos strong it was), people could die but land earthquake is generally more safer than if there was a earthquake underwater. if that happened there would be tsunamis along the coast and everything in its path would be destroyed and your belongings and stuff like cars could be in another town. hope this helps :)

Which statement best explains the speed of light waves as they travel from gas to solid?
igomit [66]

Answer:

Light waves slow down as they travel from gas to solid.

Explanation:

The speed of light is often quoted with reference to a vacuum. Light travels fastest in a vacuum and in a gas.

When light travels through other media such as solids or liquids, the speed of light is decreased due to absorption and scattering of photons by molecules as well as remissions.

Hence the speed of light decreases from gas to solid.
