Answer:
d=510.2m
t=10.2s
Explanation:
The formulas for accelerated motion are:
From them we can get .
We have:
And substitute:
We multiply both sides by 2a, and continue:
Being d the displacement , we have
For our exercise, we will write this as:
And taking upwards direction positive and imposing final velocity 0m/s (for maximum height), we have:
For the time we use:
Answer:
d.The wavelength of light and the size of the aperture
Explanation:
<em>The resolution power of an optical system is the smallest distance between two points that the device can distinguish clearly.</em>
It has the following relationship:
where:
r = minimum resolvable distance
n = numerical aperture
= wavelength of the light used for viewing
From above mathematical equation it is clear that:
(Note, that smaller the value of "r" the more finer details of the image visible through the device.)
Answer:
The answer is
Explanation:
The amount of energy is not enough to apply the relativistic formula of energy , so the definition of energy in this case is
.
From the last equation,
where
and the mass of the neutron is
.
Then
the equivalent of the speed of light.
