<h3><u>Answer;</u></h3>
Electromagnetic and transverse
<h3><u>Explanation</u>;</h3>
- Electromagnetic waves are types of waves which do not require material medium for transmission.
- Transverse waves are waves in which the vibration of particles is perpendicular to the direction of wave motion.
- All electromagnetic waves are transverse waves and travels with the speed of light. They include; gamma rays, x-rays, UV light, radio waves, and microwaves among others.
<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg

The correct answer is:
<span>Point charges must be in a vacuum.
In fact, the usual form for of the Coulomb's law is:
</span>

<span>where
</span>

is the permittivity of free space
<span>q1 and q2 are the two charges
q is the separation between the two charges
However, this formula is valid only if the charges are in vacuum. If they are in a material medium, the law is modified as follows:
</span>

where

is the relative permittivity, which takes into account the dielectric effects of the material.
