Answer:
A wavelength is a measure of distance between two consecutive crests or trough. So , the unit of wavelength is same as unit of distance. I.e metre
The force on the fry is 
Explanation:
We can find the force acting on the fry by using Newton's second law:

where
F is the net force on the fry
m is its mass
a is its acceleration
For the fry in this problem,


Therefore, the force exerted on the fry is

Answer:
The reactive part of a circuit changes electrical energy into another form of energy.
Explanation:
The reactive part of a circuit changes electrical energy into another form of energy.
The inductive part of a circuit changes electrical energy to magnetic energy and the capacitive part of a circuit changes electrical energy to electrostatic energy.
The difference between the parts of the plot with positive slope and the parts with negative slope can be found below.
<h3>What is a slope?</h3>
A slope in a graph is the ratio of the vertical and horizontal distances between two points on a line. Slope shows both steepness and direction of values.
A slope can either be positive or negative depending on the relationship between the variables being plotted.
A positive slope means that the variable are directly related while the negative slope means that two variables are negatively related.
A positive slope further means that the line moves upward when going from left to right on the graph while with the negative slope, the line moves down when going from left to right.

Explanation:
Nutrient deficiency causes yellowing of leaves. One of such nutrient is Nitrogen.
- Leaves are green because of a pigment in them called chlorophyll.
- The chlorophyll in leaves are used by plant to absorb light energy needed for photosynthesis.
- Other wavelength of light is absorbed by the chlorophyll and the green color is reflected.
- Nitrogen is an important nutrient that is needed to produce chlorophyll in plants which in turn helps the process of photosynthesis.
