Answer:
The maximum speed of the stone without breaking the rope is 4.33 m/s.
Explanation:
Given;
maximum tension the rope can withstand, T = 75 N
mass of the rock, m = 6 kg
radius of the circle, r = 1.5 m
As the stone spin in a vertical circle, it performs circular motion with centripetal acceleration directed inwards. The maximum centripetal force during this motion will be equal to maximum tension on the rope.
Therefore, the maximum speed of the stone without breaking the rope is 4.33 m/s.
Answer:
The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A. Notice that the forces are exerted on different objects.
Explanation:
Answer:
Explanation:
The force is equal to the negative of the derivative of the potential energy function:
In this problem, the potential energy function is
Therefore, the force function is:
So, adding the units of measurement,
In a person's forties, they are in the middle of stagnation vs. identity, so they are having an identity crisis.
Answer:
<em>No, the coil will produce no flow of current or potential difference.</em>
Explanation:
Magnetic field flux is the number of magnetic field line passing through a given area. It depends on the area and the magnetic field strength through this area. For electromagnetic induction to occur, there must be a constantly changing magnetic field. This is according to Faraday's law of electromagnetic induction that states that the induced EMF is directly proportional to the rate of change in flux ΔФ/Δt, and is also proportional to the number of turns on the coil. A changing magnetic field will lead to a break in the flux linkage, which induces current or potential difference on the coil. A stationary coil through a magnetic filed will therefore produce no electric flow of current or potential difference on the coil.
