Answer:
The straight line that is obtained, intercept it on the y-axis and the value of displacement will obtained.
Explanation:
If the elevator's speed is constant (in ANY direction) and you can't see out of it, then there's NO measurement you can make inside that will tell you that it's moving. Any weight you measure is normal.
Answer
given,
weight of airplane,W = 10,100 lb
Wing area,A = 233 ft²
now,
Wing Loading Calculation in English engineering
= 
= 
= 43.35 lb/ft²
Wing Loading in SI unit
= 
= 
Wing loading in kgf/m²
= 
= 211.57 kgf/m²
The change in energy after the collision is <u>0.5</u>
<u />
<h3>What is change in energy?</h3>
This refers to the difference in the energy where energy is the capacity to do work. There different forms of energy they include mechanical energy, solar energy, electrical energy and so on.
The energy described in the problem is mechanical energy and it is of two types kinetic energy and potential energy
<h3>solving for the change in energy as a result of the collision</h3>
where mass of particle mp = 4 kg
mass of object mb = 6 kg
force constant of spring k = 100 N/m
amplitude A = 2 m
kinetic energy = 1/2 mv^2
initial velocity u = Aω
ω = sqrt ( 100/ 4 )
u = 2 sqrt ( 100/ 4 )
u = 10m/s
final velocity v = 5 m/s
change in energy
= - 0.5 * ( 4 + 4 ) * 5^2 + 0.5 * 4 * 10^2 ) / 0.5 * 4 * 10^2
= 0.5

Answer:
Reflection is simply the property of a light that rebounds or bounces back after hitting a surface.
Refraction is when the light, which passes through a surface, undergoes some changes in appearance whenever it usually passes through a medium.
