The eagle would have more momentum. The formula for momentum is mass times velocity, and since the eagle has a significantly greater mass, its momentum would also be greater.
Explanation:
Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.
The frequency and the wavelength has an inverse relationship.
For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.
The frequency range of visible region is from 400 nm to 700 nm.
In my opinion it does. The more water the pot holds, the longer you need to wait for it to freeze. Since there is more water, some parts may not be completely frozen. An experiment you can try is to get an ice cube container and a pot. fill both of them and put them in the freezer for the same amount of time. When you take it out, the ice cubes should be frozen leaving the pot with cold water.
a) 189.2 J
b) 13.5 W
Explanation:
a)
The work done by the force on the package is equal to the scalar product between force and displacement:
where F is the force and d is the displacement.
In this problem, the force is:
We know the initial position:
and the final position:
So, the displacement is the difference between the two positions:
Therefore, the scalar product between force and displacement is:
b)
The average power of the machine is the rate of work done per unit time; it is given by
where
W is the work done
t is the time elapsed
In this problem, we have:
W = 189.2 J (work done)
t = 14.0 - 0 = 14.0 s (time elapsed)
Therefore, the average power of the machine is:
