Answer:
Force,F =
Explanation:
Given that,
Charge 1,
Charge 2,
Negative charge is 0.002 m north of a positive charge, distance between charges, d = 0.002 m.
Let is the magnitude of electrical force applied by q₁ on q₂. We know that the electrical force is given by the formula as follows :
So, the electrical force applied by q₁ on q₂ is towards north.
Part A.
To get the acceleration of the system we consider the two blocks as a single mass. For this situation we have, from Newton's second law, that:
where T is the tension in the upper sting and W is the weight of the system. Solving the equation for a we have:
Therefore the acceleration of the system is 2.42 meters per second per second.
Part B.
Now, that we have the acceleration of the system we analyze the lower block individually; for this block the equation of motion is:
where T' is the tension in the lower rope, W' is the weight of the lower block and m2 is its mass. Solving for the tension we have that:
Therefore the tension in the lower rope is 2.93 N
Answer:
gym and gym work 6.30 and I have been a very good friend a
Answer:
1. Since the carpet is softer than the concrete and the force of impact is reduced by the extended time of impact.
Explanation.
The carpet provides energy dissipation over a porous layer of material.
Because of this, the carpet behaves as if it was a spring and a dashpot.
The spring absorbs the kinetic energy, and the dashpot dissipates the energy.
The ticker the carpet, the better the energy dissipation will be.
Explanation:
Speed = 10 and miles = 5
(a) Speed + 12 – miles * 2
10 + 12 - 5 × 2
= 12
(b) speed + miles × 3
10 + 5 × 3
= 25
(c) (speed + miles) × 3
(10 + 5) × 3
= 45
(d) speed + speed × miles + miles
10 + 10 × 5 + 5
= 65
(e) (10 – speed) + miles / miles
(10 - 10) + 5/5
= 1
Therefore, this is the required solution.
