Answer:
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.
Explanation:
Well first of all the atomic mass is the number of protons + the number of neutrons this is the mass of the nucleus and meaning that the protons and neutrons make up the nucleus which is where all the mass is located. So the number of protons will be equal to the number of electrons if it is a neutral atom. So the atomic number of Lithium is 3 and this is equal to the number of protons. So if you want to find the number of neutrons you have to subtract the number of protons which in this case is 3, so you're going to subtract 3 from 6 (6-3) and this is going to leave you with 3 neutrons. So in this case there are 3 Protons, 3 Neutrons, And 3 Electrons.
There are three different types of intermolecular forces in terms of strength. They are (strongest to weakest) hydrogen bonding, dipole-dipole and Van der Waals' forces.
The heat absorbed to raise temperature : Q = 31350 J
<h3>Further explanation
</h3>
Given
m = mass = 150 g
Δt = Temperature difference : 50 °C
Required
Heat absorbed
Solution
Heat can be formulated
<em>
Q = m.c.Δt
</em>
The specific heat of water = c = 4.18 J/g °C
Input the value :
Q = 150 x 4.18 x 50
Q = 31350 J
The statement that is true is that B. Atoms always remain intact during chemical reactions.
Atoms simply mean the <u>basic units of matter.</u> They're the defining structure of an element. Atom is also known as the smallest unit of matter.
It should be noted that atoms always remain intact during chemical reactions. They cannot be added and removed when there are <em>chemical reactions.</em>
