What happens to the energy when the material is changed?

Physics
1 answer:
expeople1 [14]3 years ago
3 0

Answer: When a material is heated or cooled, two changes may happen to the particles within the material: Chemical bonds between the particles may form, break or stretch. There is a change in the chemical potential store of energy in the material. The material will heat up or cool down as the particles within it gain or lose speed.

PLEASE HELP !!!
emmainna [20.7K]

Answer and Explanation:

The answer is <u>D) Alpha and Gamma</u>

Gamma radiation does not cause transmutations.

A <u>transmutation</u> is the <u>conversion of an atom of one element to an atom of another. This generally occurs through nuclear reacting.</u>

There are three main types of radiation: alpha, beta, and gamma. Both beta and alpha decay cause changes to the mass and atomic numbers. This results in a transmutation. Gamma radiation, however, does not.

Gamma radiation is the result of a gamma ray. In essence, the nucleus emits a high-energy proton. This is very penetrating and can only be stopped by aluminum, lead, soil, water, and concrete. This type of radiation does not change the element and, therefore, does not cause a transmutation.

A 2.35 kg ball is attached to a ceiling by a3.53 m long string. The height of the room is5.03 m .The acceleration of gravity is
Studentka2010 [4]

Answer:-81.29 J

Explanation:

Given

mass of ball m=2.35 kg

Length of string L=3.53 m

height of Room h=5.03 m

Gravitational Potential Energy is given by

P.E.=mgh

where h=distance between datum and object

here Reference is ceiling

therefore h=-3.53 m

Potential Energy of ball w.r.t ceiling

P.E.=2.35\times 9.8\times (-3.53)=-81.29 J

i.e. 81.29 J of Energy is required to lift a ball of mass 2.35 kg to the ceiling
