Answer:
Fatty acids.
Explanation:
-Long term energy storage is stored in the form of triglycerides .
-They are efficient storing molecules. They are more efficient thatn glycogen(cabohydrates).
-Fatty acids are more calori dense hence them being ideal for long term energy storage.
The frequency is 
and it is blue light
Explanation:
The relationship between the speed, the frequency and the wavelength of an electromagnetic wave is given by:
where
is the speed of light
f is the frequency of the wave
is its wavelength
In this problem, the wavelength of the wave is
Therefore, its frequency is:
The wavelength of this wave is
And by looking at the table of the wavelengths of the colors, we notice that this corresponds to the blue light, which has a range of wavelength of
[450 - 495] nm

Answer:
Explanation:
Given: that,
Angle of inclination of the surface, 
mass of the crate, 
Force applied along the surface, 
distance the crate moves after the application of force, 
a) work done = F× s
work done = 230 × 1.1
work done = 253 J
b) Work done by the gravitational force:
where:
g = acceleration due to gravity
h = the vertically downward displacement
Now, we find the height:
So, the work done by the gravity:
∵direction of force and displacement are opposite.
= - 343.54J
c)
The normal reaction force on the crate by the inclined surface:
d)
Total work done on crate is with respect to the worker:
Answer: The total resistance in a parallel circuit is always less than any of the branch resistances. Adding more parallel resistances to the paths causes the total resistance in the circuit to decrease. As you add more and more branches to the circuit the total current will increase because Ohm's Law states that the lower the resistance, the higher the current.
Explanation:
In an experiment there are three types of variables: Independent, dependent and constant variables.
The variable being tested and the parameters of which can be changed is the Independent variable. Here, the cleaning product is the independent variable.
Dependent variables are the ones which vary when change in the independent variable is made. How clean the counter is the dependent variable which is depending on the cleaning product (the independent variable).
Constant variables are the ones which are kept unchanged during the experiment so that it does not affects the result of the experiment. In the given experiment, the amount of cleaning product and the brand of the paper towel are the constant variables. Other constant variables can be the size of the paper towel, the technique of wiping, the temperature etc.
