Answer:
gggggggggggggggggggggggggggggggggg
Explanation:
Impulse, denoted as J, is defined by the change in momentum. Since we have our initial and our final, we can solve for the change in momentum.
The inability to maintain posture while standing still would indicate a problem with the static equilibrium receptors. S<span>tatic equilibrium receptors provide information about body position relative to the force of gravity: standing upright v. being upside done. Hope this helps.</span>
Answer:
A) weakly attracted
B) negative charge on end A with B remaining almost neutral
C) strongly repelled
Explanation:
A)
- As the negatively charged ball is brought close to the end A of the road, positive charges on this end try to move away from there, leaving a small negative charge in this end, as they are not free to move as in a conductor.
- As a consequence of this, the end A of the road will be weakly attracted by the negatively charged ball.
B)
- After several contacts between the ball and the end A of the rod, an appreciable quantity of negative charge has been deposited in the end A, repelling positive charges towards the end B.
- However, as the rod is an insulator, positive charges can't travel massively to the end B, so it remains almost neutral.
C)
- After repeated contacts that have deposited a significative negative charge on the end A (which can't distribute evenly as in a conductor), when the ball (negatively charged) is brought close to this end of the rod, as both bodies have the same type of charge, they will be strongly repelled each other.
Answer:
v₁ = 1.78 m/s
Explanation:
We can use the law of conservation of momentum here, as follows:
where,
m₁ = mass of first object = 4.5 kg
m₂ = mass of second object = 6.2 kg
u₁ = initial speed of first (smaller) mass = 16 m/s
u₂ = initial speed of second (larger) mass = 0 m/s
v₁ = final speed of first (smaller) mass = ?
v₂ = final speed of second (larger) mass = 10 m/s
Therefore,
<u>v₁ = 1.78 m/s</u>
