Answer:

\dfrac{dE}{dt}=2.59\times 10^{12}\ V/m.s

Explanation:

Given that

R= 0.19 m

r= 0.28 m

I= 2.6 A

We know that

I_D=\epsilon _oA\dfrac{dE}{dt}

A= Area of loop

dE/dt= rate of change of electric filed

I=Displacement current

Here r>R

So A=π R²

Now by putting the values

I=\epsilon _oA\dfrac{dE}{dt}

2.6=8.85\times 10^{-12}\times \pi\times 0.19^2\dfrac{dE}{dt}

\dfrac{dE}{dt}=2.59\times 10^{12}\ V/m.s

Four pairs of objects have the masses as described below, along with the distances between
lord [1]

Answer:

<h2>Mass of 1 Kg and 2 Kg, 1 meters apart.</h2>

Explanation:

The gravitational force is defined as

F=G\frac{m_{1} m_{2} }{r^{2} }

By definition, the gravitational force depends directly on the product of the masses and indirectly on the distance between the masses, which means the further they are, the less gravitational force would be. And, the greater the masses, the greater the gravitational force.

Among the options, the pair that would have the greatest gravitational force is  Mass of 1 Kg and 2 Kg, with 1 meter between them.

Notice that the last choice includes the same masses but with a greater distance between them, that means it would be a weaker graviational force.

Therefore, the right answer is the second choice.

Brandon pushes an object on a ramp as shown in the diagram.
stiks02 [169]

The force which has the greatest effect on causing this object to slow while it remains in contact with the ramp is: B. a frictional force.

<h3>What is a force?</h3>

A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.

<h3>The types of force.</h3>

In Science, there are different types of force and these include the following:

  • Gravitational force
  • Tension force.
  • Electrical force
  • Normal Force.
  • Magnetic force
  • Air resistance force
  • Applied force
  • Frictional force.

<h3>What is a frictional force?</h3>

Friction force can be defined as a type of force that resists and slows the relative motion of two physical objects when there surfaces come in contact. This ultimately implies that, a frictional force prevents two surfaces from easily sliding over or slipping across one another.

In this context, we can infer and logically deduce that the force which has the greatest effect on causing this object to slow while it remains in contact with the ramp is a frictional force.

If there is no friction in a rollercoaster is the speed the same throughout?
andrey2020 [161]
If there is no friction, the roller coaster would keep moving forever but a constant velocity. The only way it would accelerate is if there was a force continually pushing on it.
