The answer is:

Heat transfer.In order to heat up water there has to be a way that the heat puts energy into the water,which make is rise in temperature.

I hope this helps :D

What involves the movement of electrons in neutral objects due to the electric field produced by a charged object?

ELEN [110]

Answer: Polarization

Explanation: Polarization is the movement of electrons within a neutral object because of the electric field of a nearby charged object. It occurs without direct contact between the two objects.

For example, electrons in a metal plate can repelled by the negative charges in a plastic rod if the plastic rod is placed near the metal plate. The electrons move away from the plastic rod, thereby causing one side of the metal plate to be positively charged and the other side to become negatively charged.

A projectile is launched horizontally from the top a 35.2m high cliff and lands a distance of 107.6m from the base of the cliff.

tankabanditka [31]

Answer:

$v_o=40.14\ m/s$

Explanation:

<u>Horizontal Launch </u>

It happens when an object is launched with an angle of zero respect to the horizontal reference. It's characteristics are:

The horizontal speed is constant and equal to the initial speed $v_o$
The vertical speed is zero at launch time, but increases as the object starts to fall
The height of the object gradually decreases until it hits the ground
The horizontal distance where the object lands is called the range

We have the following formulas

$\displaystyle v_x=v_o$

$\displaystyle x=v_o.t$

$\displaystyle v_y=g.t$

$\displaystyle y=\frac{gt^2}{2}$

Where $v_o$ is the initial horizontal speed, $v_y$ is the vertical speed, t is the time, g is the acceleration of gravity, x is the horizontal distance, and y is the height.
