When plastic deformation of a material occurs, the material _____. regains its original shape when the stress is removed is perm
anently deformed becomes magnetic at low temperatures becomes highly resistant to stress
2 answers:
Answer: Is permanently deformed.
Explanation (see the diagram shown below).
For most structural materials:
(a) The deformation in the elastic zone is recoverable, and the material returns
to its original shape when the load (or stress) is removed.
(b) A permanent set (non-recoverable deformation) occurs when the material
is sressed beyond the elastic zone, that is, in the plastic zone.

Answer:
The recoil velocity is 0.354 m/s.
Explanation:
Given that,
Mass of hunter = 70 kg
Mass of bullet = 42 g = 0.042 kg
Speed of bullet = 590 m/s
We need to calculate the recoil speed of hunter
Using conservation of momentum
Where, = mass of hunter
= mass of bullet
u = initial velocity
v = recoil velocity
Put the value in the equation
Hence, The recoil velocity is 0.354 m/s.
Answer:
Explanation:
Given that the airplane starts from the rest (this is initial velocity equals to zero) and accelerates at a constant rate, position can be described like this: where x is the position, t is the time a is the acceleration and
is initial velocity. In this way acceleration can be found.
.
Now we are able to found velocity at any time with the formula:
