Explain which has a greater inertia - a speeding car or jet plane sitting on a runway?

Answers

Explanation:

Inertia is related to only mass, not speed.

Since a jet plane has more mass than a car, it has more inertia.

A net force of -1,000 Newtons is delivered to the object over a time of .02 seconds. Calculate the new velocity of the object.

Answers

The change in velocity (v₂ - v₁) is

(-20) / (the object's mass).

Call it a crazy hunch, but I can't shake the feeling that there was more

mass, and its velocity before this force came along.

How do charges move through an insulated wire connected across a battery? Use the terms potential difference, current, conductor, and insulator in answer.

Answers

The battery has both a positive side and a negative side. The potential difference will be the potential of the positive end of the battery minus the potential of the negative end, which will result in positive potential, or power. This potential is what gives the electrons the ability to flow from the positive end to the negative end, or to make a current. While the outside of the insulated wire is the insulator, the inside of the wire has copper, which is the conductor of the current. So, this current will go through the copper of the wire (and not the insulator) from the positive side to the negative.

Answer:

Battery is the source of electrical energy which will help the charge to flow through a medium.

Battery is a constant source of potential difference which will create constant potential difference across the ends of a conductor where it is connected.

When a charge is passed through the constant potential difference then the change in electrostatic potential energy will give kinetic energy to the charge.

It is given as

$q\Delta V = (1)/(2)mv^2$

so here charge will continuously flow through the conductor across which potential difference is applied by the battery. This constant motion or flow of charge is known as electric current.

An object placed in water will float if the weight of the object is MORE THAN the buoyant force of the water.True
False

Answers

False

If the object weighs more than the buoyant force then the object will sink.

This is because the buoyant force "pushes" the object upwards and the weight of the object "pushes" the object downwards. Since the force downwards is greater than the force upwards the item will sink, so this statement is False.

As you run toward a source of sound, you perceive the frequency of that sound to

Answers

As you run toward a source of sound, you perceive the frequency of that sound to decrease.

Explanation:

Doppler's effect is a principle used to describe the frequency and the intensity of sound and wavelengths of a source and observer with the two possibilities.

(i) Stationary sound source and moving observer.

(ii) Moving sound source and a stationary observer. It is a relative motion.

Consider when the observer is moving towards a source, the frequency of the sound will be higher and when moving away from the source, the frequency will decrease.

frequency is the speed of vibration and this determines the pitch of the sound. it is only useful or meaningful for musical sounds. where there is a strongly regular waveform. frequency is measured as the number of wave cycles that occur in one second. the unit that is being measured is (hz)
