Thermal energy gives the particles of the substance kinetic energy because temperature is an average measure of kinetic enegy of the particle. If we give them thermal energy the particle will move faster, gaining enough energy to escape and become free. For example, from solid to liquid, the particles would espace their fixed position and be free to move as a liquid.

MrRissso [65]

Answer:

Nanotechnology refers to the branch of science and engineering devoted to designing, producing, and using structures, devices, and systems by manipulating atoms and molecules at nanoscale, i.e. having one or more dimensions of the order of 100 nanometres (100 millionth of a millimetre) or less.

krok68 [10]

Given :

An 80kg sled rider starts sledding down a 100m hill from rest. If her final velocity is 15m/s.

To Find :

The acceleration down the hill.

The force needed for that kind of acceleration.

Solution :

By equation of motion :

v^2 -u^2 = 2as\\\\a = \dfrac{v^2-u^2}{2s}\\\\a = \dfrac{15^2 -0^2}{2\times 100}\\\\a = 1.125\ m/s^2

Force required is, F = ma

F = 80×1.125 N

F = 90 N

Hence, this is the required solution.

1.) if the total momentum for a system is the same before and after the collision, we say that momentum is conserved. if momentu
gogolik [260]

From the law of the conservation of energy;  the ratio of the total kinetic energy after the collision to the total kinetic energy before the collision must be 1.

<h3>What is momentum?</h3>

The term momentum is the product of mass and velocity. The principle of conservation of linear momentum states that total momentum before collision must be the same as the total momentum after collision thus the  ratio of the total momentum after the collision to the total momentum before the collision must be 1.

Also, from the law of the conservation of energy;  the ratio of the total kinetic energy after the collision to the total kinetic energy before the collision must be 1.
