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:
- Smaller the wavelength better the resolving power
- Larger the aperture better the resolution
(Note, that smaller the value of "r" the more finer details of the image visible through the device.)
Answer: No endorphins
Explanation: cuz' she injured her ankle
Mass of the object m = 25 kg
Coefficient of friction Uk = 0.15
Frictional force Ff = Uk x F => Ff = Uk x m x g
Ff = 0.15 x 25 x 9.8
Frictional Force Ff = 36.75 N
Answer:
A
Explanation:
The line(A) goes throughout the entire picture. So therefore choice A would be it's length.
Use the formula below for this question:
re-arrange to solve for a:
now simply plug in your variables and there's your answer :). If you ever get stuck, you can look up the kinematic equations!
