A matchstick has a lot of chemical energy stored in it. When the match is struck, it burns and the chemical energy in it produces heat energy and light energy.
<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.
Sounds like the answer is c
If we consider that the surface wherein this box is located is frictionless in such a way that the friction does not affect its motion, we can calculate for the horizontal force by multiplying the force with the sine of the angle.
x-component of force = (4 N) x (sin 62°)
= 3.53 N
