Answer:
Yes
Explanation:
I think our memories can be altered by emotions. If someone tells you something over and over and over again with strong emotion you will start to remember that more than the memory.
Emotions are very powerful and if you feel a certain emotion connected with a different memory I think that is stronger and can trick your brain into thinking that is the memory because of the strong emotion, even though the true memory was right, since it might not have as strong of mental emotion your brain will think that is the false memory because whatever is more memorable your brain will remember.
If that makes any sense,
It will be <span>Einstein's General Relativity</span>
<span>a shock wave first forms when an object Reaches the speed of sound
When an object reaches the speed of sound, it will create some sort of disturbance in the air that created discontinuous change in pressure, medium density and the temperature around it, which will eventually became a shock wave.</span><span />
Answer:
2.1 m/s²
Explanation:
By definition, the angular acceleration, is equal to the rate of change of the angular velocity, ω:
α = Δω / Δt (1)
By definition of the angular velocity, we can express the linear velocity, v, as follows:
v = ω*r⇒ Δv = Δω*r (2)
Replacing Δω, from (1) in (2), we get:
Δv = α*Δt*r⇒ Δv/Δt = α*r (3)
By definition of linear acceleration, we can write the following expression;
a = α*r
For a point on the edge of the wheel, the linear acceleration is tangent to the rim, and is equal to the product of the angular acceleration times the distance to the center, which for a point on the edge of the wheel, is just the radius:
⇒ a = 7 rad/sec²*0.3m = 2.1 m/s²
When the elevator moves downward, the man weighs less because of the inertia.
Force of Weight:Fg=m×g
Fs=m×g-m×1/4g=m×(g-1/4g)=m×3/4g
If He Went Up you would have to add 1/4g
