Answer:
I'm pretty sure it's 20m/s because 1300m divided by 65 seconds is 20 so I think it's 20m/s
Explanation:
Q. Are seismic waves mechanical or electromagnetic waves?
A. Seismic waves are mechanical waves.
Q. Are seismic waves transverse or compressional waves?
A. Seismic waves are compressional waves.
When two objects<span> that are at </span>different temperatures come<span> into </span>contact... heatalways<span> transfers from the </span>object<span> with the higher </span>temperature<span> to the </span>object<span> with the lower temp. the total energy of the particles that make up a substance. In thermal energy the more particles there are of a given substance</span>
A beta particle followed by another beta particle. Consider it beta positive decay in which a proton decays to form a neutron,positron and electron neutrino.
Explanation:
It is given that,
The rest mass of the particle, 
Speed of the particle, v = 0.5c
Firstly calculating the relativistic factor. The formula is as follows :



1. Inertial mass is given by :


2. The momentum is given by :



3. Kinetic energy of the particle is given by :

4. The total energy of the particle is :



Hence, this is the required solution.
