Well because it has momentum and it needs to be slowed down.

Answered
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:
B. Arsenic
Explanation:
76 - 43 = 33 protons
on a periodic table element 33 is Arsenic
Answer:
a. 125 kJ
Explanation:
Her total energy is the same as the potential energy she had at the top of the hill:
PE = mgh
= (52 kg)(9.8 m/s^2)(245 m) = 124,852 J
≈ 125 kJ . . . . matches choice A
_____
After skiing down 112 m, some of her initial energy is converted to kinetic energy, and some remains as potential energy. We assume the ski slope is essentially frictionless, and air resistance is negligible.
