Explanation:
The data given in the problem
Diameter of a human pupil=0.007 m=7 mm
Diameter of alien pupil=0.5=500 mm
Here we have to calculate the minimum distance at which the alien can see Betelgeuse i.e. the focal length (or the working distance). For this calculation we assume the eye to be a spherical lens.
The focal length and diameter of the lens are related by the formula
Where r is radius of curvature i.e. d/2
Therefore for the alien, focal length=
=12.5mm=0.0125
Answer:
P = 517.5 [kg*m/s]
Explanation:
We must remember that momentum is defined as the product of force by the time of force duration.

where:
P = momentum [kg*m/s]
F = force [N]
t = time [s]
![P=345*1.5\\P=517.5[kg*m/s]](https://tex.z-dn.net/?f=P%3D345%2A1.5%5C%5CP%3D517.5%5Bkg%2Am%2Fs%5D)

Explanation:
Hi there!
Recall the equation for kinetic energy:

KE = Kinetic energy (J)
m = mass (kg)
v = velocity (m/s)
Plug in the given values:
