Answer:
upwards
downwards
Explanation:
Given:
weight of the person,
So, the mass of the person:
- Now if the apparent weight in the elevator,
<u>Then the difference between the two weights is :</u>
is the force that acts on the body which generates the acceleration.
Now the corresponding acceleration:
upwards, because the normal reaction that due to the weight of the body is increased here.
- Now if the apparent weight in the elevator,
<u>Then the difference between the two weights is :</u>
is the force that acts on the body which generates the acceleration.
Now the corresponding acceleration:
downwards, because the normal reaction that due to the weight of the body is decreased here.
Answer:
just use the formula λ = v/f
Explanation:
v = velocity
f = frequency
<span>This problem asks that we compute the magnitude
of the maximum stress that exists at the tip of an internal crack
</span> sigmam=2*(sigma0)(a/(pt))^(1/2)
sigmam= 2*(180)*(((3.5×10^-2)/(2))/(4.5×10-4))^(1/2)=2245 MPA (325609.7 PSI)
I think it’s mechanical waves..
