<h3>Answer</h3>
option C)
The wavelength has a length between 7.0 cm and 8.0 cm and the amplitude lies between 1.0 cm and 2.0 cm.
<h3>Explanation</h3><h2>1)</h2>
The amplitude of a wave is the height of a wave as measured from the highest point on the wave, peak, to the rest point or from the lowest point on the wave, trough, to the rest point.
By looking at the image
rest point is at 5cm and crest is at 3.3 cm (y-axis)
so amplitude = 5 - 3.3
= 1.7 cm (approximately)
<h2>2)</h2>
Wavelength refers to the length of a wave from one peak to the next.
one crest is at 2cm and the other crest is at 10cm (x-axis)
so wavelength = 10 - 2
= 8 cm (approximately)

If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
If you are working with electricity most people will measure it in watts.
So, A. watts is your best answer.

The frequency of a simple harmonic oscillator such as a spring-mass system is given by
where
k is the spring constant
m is the mass attached to the spring.
Re-arranging the formula, we get:
and since we know the constant of the spring:
and the frequency of oscillation:
f=1.00 Hz
we can find the value of the mass attached to it:
Answer:
If transpiration didn't take place water would still be able to enter the roots of a plant
Explanation:
transpiration is the process of water leaving from living organisms to the atmosphere, therefore, if transpiration didn't occur the water would not transpire to the atmosphere and would remain in the root but water absorption would not change because it is a biological need for the living organism as such
