Key Takeaways
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.

Answer:
A microwave
Explanation
The human retina can only detect incident light that falls in waves 400 to 720 nanometers long, so we can't see microwave or ultraviolet wavelengths. This also applies to infrared lights which has wavelengths longer than visible and shorter than microwaves, thus being invisible to the human eye.
Short Answer- Friction
<span>
Explanation- There is friction between the grass and the ball. Friction is a type of force that limits motion between two surfaces that are touching. Friction is the force that one surface exerts on another with the two surfaces rubbing together.

This is the answer, hope it helps :)
Answer:
4.8 m
Explanation:
A transverse wave is a wave in which the oscillation of the particles occur in a direction perpendicular to the direction of motion of the wave.
The amplitude of a transverse wave is the maximum displacement of the wave with respect to the equilibrium position.
The crest of a wave is the position of maximum displacement on the positive side, while the trough of a wave is the position of maximum displacement on the negative side.
This means that the amplitude of a wave is equal to the distance between a crest (or a trough) and the equilibrium position.
Therefore, we have:
where:
d is the distance between the top of a crest and the bottom of a trough
A is the amplitude of the wave
Here we have:
A = 2.4 m
So, we find
