Answer:
h = v₀² / 2g
, h = k/4g x²
Explanation:
In this exercise we can use the law of conservation of energy at two points, the lowest, before the shot and the highest point that the mouse reaches
Starting point. Lower compressed spring
Em₀ = K = ½ m v²
Final point. Highest on the path
= U = mg h
As or no friction the energy is conserved
Em₀ = Em_{f}
½ m v₀²² = m g h
h = v₀² / 2g
We can also use as initial energy the energy stored in the spring that will later be transferred to the mouse
½ k x² = 2 g h
h = k/4g x²
Answer:
To reverse all types of defects.
Explanation:
In the magnetic particle inspection method the material which is used in testing will utilize the magnet which is ferromagnetic and it is high permeable and the retentivity of this magnet is low.
It is a technique which is not destructive and this technique is used for detecting the surface and the hollow part of ferromagnetic substance and will reverse all these defects.
Therefore, circular and longitudinal way of magnetization will reverse all the types of defect.
The choices above are social psychology terms
that help describe the people’s actions in their everyday interaction with
people. The sentence example is:
Those computer geeks are all the same.
They
spend all day playing video games and programming their computers to serve them
breakfast. I don't think I've ever seen one reading a real book or throwing a
baseball. Why, they're almost like machines!
