Answer:
658.16N
Explanation:
Step one:
given data
mass m= 235kg
Force F= 760N
angle= 30 degrees
Required
The horizontal component of the force
Step two:
The horizontal component of the force
Fh= 760cos∅
Fh=760cos30
Fh=760*0.8660
Fh=658.16N
the wavelength is 2.2m
wavelength can be calculated by formula wavelength = velocity / frequency so here first we need to find the velocity so velocity is distance travelled/time taken that 2 X 10^8 m/s now wavelength is = 2 X 10^8/ 90=2.2m.
Waves are signals that can go through various media, including wire in the case of an electrical AC current, water, light, and other media. The separation between two identical points on a sinusoidal wave is known as the wavelength. You can determine how long there is between each wave's peak and each wave's trough if you know the frequency of the wave moving through the medium.

Answer:
2ms-¹ means that the body under consideration moves 2m in a second, and may be it will continue to move 2m in every 1 second, if there's no external unbalanced force acting on that body (those forces do include frictional forces). mark its brainlist plz.

<h3><u>Answer;</u></h3>
A compound which is a pure substance
<h3><u>Explanation;</u></h3>
- <em><u>A pure substance is a substance with a definite and constant composition and distinct chemical properties. Pure substance can either be a compound or an element.</u></em>
- <em><u>Compound is a substance made of two or more elements that can be broken down by chemical means. therefore, Chemical reaction is the only way to separate a compound into its elements</u></em>
- Element on the other hand is a pure substance that is composed of only one type of atom. Unlike compounds pure substances can not be broken down by chemical means.
