Wave C has an amplitude of 1 and wave D has an amplitude of 3 as shown below. What will happen when the trough of wave C meets the crest of wave D?

Answers

Answer:

They will interfere to create a crest with an amplitude of 2.

Explanation:

If the crest of one wave meets the trough of another wave, destructive interference occurs and the combined amplitude will be less than that of either wave alone. If the amplitudes of the two waves are equal, when the crest and trough superimpose, the combined amplitude will be zero.

A circuit component with a high resistance will have a low electric current. a. True
b. False

Answers

You haven't said what 'high' resistance or 'low' current means, so there's way not enough info to nail the statement as true or false. The most precise answer is "certainly could be but not necessarily". Anyway, the current in the circuit depends on BOTH the resistance AND the voltage. So without knowing the voltage too, you can't say anything about the current.

A helium balloon containing 5m³ of gas at a pressure of 30kPa is released into the air. Assuming that the temperature is constant calculate the volume the balloon would have when the pressure inside the balloon has fallen to 5kPa. Answer in m³.

Answers

Answer:

30 m³

Explanation:

Parameters given:

Initial volume of helium, V1 = 5 m³

Initial pressure in balloon, P1 = 30 kPa

Final pressure, P2 = 5 kPa

To find the volume of the balloon at that volume, we apply Boyle's law.

It states that at constant temperature, the pressure of a gas is inversely proportional to the volume of the gas.

Mathematically:

P = k / V

Where k = constant of proportionality

This implies that:

P * V = k

This means that if the pressure or volume of the gas changes at the same temperature, the product of the pressure and volume would be the same:

Hence:

P1 * V1 = P2 * V2

Hence, to find the final volume:

30 * 5 = 5 * V2

=> V2 = (30 * 5) / 5

V2 = 30 m³

The volume of the gas when the pressure is 5 kPa is 30 m³.

A coil of insulated wire is wound many times around an iron bar. The wire is connected to a battery and a contact switch. The contact switch is alternately flipped closed and left closed, so the wire carries a current through it, and then flipped open and left open, so that the current stops. Describe what magnetic fields are created, if those magnetic fields in turn induce an emf, and whether the induced emf is in the direction of the original current or opposite to it. Justify your answer using Lenz's law and the conditions which can cause a magnetic field to induce an emf. You may draw a diagram if it helps you to visualize the apparatus.

Answers

Answer:

As per faraday's law the rate of change in magnetic flux linked with a coil will induce EMF in the coil. It is given by

$E = - (d\phi)/(dt)$

now here as we are closing the switch and then open it alternatively so it will change the value of current in the coil.

This change in current will change the magnetic flux in the coil due to which it will induce EMF in it.

Now by Lenz the the direction of induce current in the coil will always opposite to the causes due to which it is induced.

As we know that when switch is connected to flow the current the direction of induced current is in opposite to the current so that it will oppose the increasing value of current while when we open the switch the induced current is in direction of the current so that it will increase the value of decreasing current in the loop.

The induced emf is in the direction opposite to the direction of current.

What is induced emf?

Emf is the production of a potential difference in a coil as a result of changes in the magnetic flux passing through it.

When the flux coupling with a conductor or coil changes, electromotive Force, or EMF, is said to be induced.

The rate of change in magnetic flux linked to a coil will induce EMF in the coil, according to Faraday's law.

Now, when we alternately close and open the switch, the current in the coil will change.The magnetic flux in the coil will vary as a result of the change in current, resulting in EMF in the coil.

Now, according to Lenz, the direction of induce current in the coil will always be the polar opposite of the causes.

Hence the induced emf is in the direction opposite to the direction of current.
