Answer:

Explanation:
Given data
Force F=2 N
Length L=17 cm = 0.17 m
Spring Constant k=42 N/m
To find
Relaxed length of the spring
Solution
From Hooke's Law we know that

The energy goes from electric energy and gets converted into thermal energy.
The ions are in fixed positions.
Explanation:
Ionic solids are poor conductors of electricity because their ions are fixed in position. Their ions are not free to move about. They are fixed in crystal lattices.
- For the conduction of electricity, compounds must possess free mobile electrons and moving ions in solution.
- Ionic compounds are formed by the electrostatic attraction between a metallic and non-metallic ion.
- They actually contain ions but their ions are locked up.
- They are not free to move about.
- Electrical conduction involves ion mobility.
- In molten and aqueous forms, they are able to conduct electricity because their ions are then mobile.

Answer: idk that is a tough one!
Explanation: that is a hard question IDK
The momentum of block B after the collision is -50 kg m/s.
Explanation:
We can solve this problem by using the principle of conservation of momentum. In fact, the total momentum of the system before and after the collision must be conserved, so we can write:

where:
is the momentum of block A before the collision
is the momentum of block B before the collision
is the momentum of block A after the collision
is the momentum of block B after the collision
Solving for
, we find:

So, the momentum of block B after the collision is -50 kg m/s.
