Answer:
a)Wt =25.68 lbf
b)Wt = 150 lbf
F= 899.59 N
Explanation:
Given that
m= 150 lbm
a)
Weight on the spring scale(Wt) = m g
We know that
Wt = 150 x 5.48/32 lbf
Wt =25.68 lbf
b)
On the beam scale
This is scale which does not affects by gravitational acceleration.So the wight on the beam scale will be 150 lbf.
Wt = 150 lbf
If the plane is moving upward with acceleration 6 g's then the for F
F = m a
We know that
a=6 g's
So
F = 90 x 9.99 N
F= 899.59 N
Electromagnetic waves can transfer energy without a material medium.
3 examples of elctromagnetic energy include: Radio wave, X-rays and gamma rays
<h3>What is wave?</h3>
A wave is a disturbance that transfers energy from one point to another.
Electromagnetic waves are waves that does not require a material medium for the tranfer of energy
- Radio wave
- Gamma rays
- X-rays
- Light wave

Answer:
T = 
Explanation:
Given,
Initial Velocity, u=0
As platoon is moving with constant velocity v,
Final Velocity, v=v
The vehicle starts from 0 to v at constant acceleration of a,
Relevent expressions:
v=u+at...........................(1)
v2=u2+2as.....................(2)
= 2aS, as S = 
,
= 2a,
From(1)
v=at
Hence
(at)^2=2a
= 
T =
This is the final expression for time.
