Mechanical
waves are oscillation of matter, they are important because they all
transfer energy from one place to another. There are 2 types of
mechanical waves. A transverse wave where the particles vibrate
perpendicular to the direction of energy travel and a longitudinal
wave where particle vibrations are parallel to the direction of the
energy transfer.

hope it helps, Regards.
<h2>Answer: Temperature
</h2>
Temperature is a physical quantity that reflects the amount of heat in a body or medium. This amount of heat is related to the internal energy of a system (thermodynamically speaking), <u>according to the movement (speed) of each of the particles that compose it</u>, this means that it is related to its kinetic energy.
Therefore, the higher the kinetic energy, the higher the thermal energy in the system and the higher the temperature.
Answer:
6 and 14 respectively
Explanation:
proton number = atomic number
mass number = proton number + neutron number
since
- p.n = a.n = 6
- m.n = p.n + n.n
- m.n = 6 + 8 = 14
- m.n = 14
There are two types of change in matter: physical change and chemical change. ... This is called the Law of Conservation of Matter. It states that matter can never be created or destroyed, only changed and rearranged.
F=Gm1m2/r^2 where G is a gravitational constant
F≈m
the greater the mass of planets, the greater the gravitation force experiment by a person
gravity of a planet (a=GM/r^2)
the larger the mass of planet , the larger the gravity of planet
Weight = mass * gravity of the planet
therefore when neutron star has the same mass as our sun, the mass is larger and the gravity of it will be very large
