The potential of electrons in a circuit can be increased by _____. flowing through the conducting wires
the action of a battery
passing through a circuit element
water pressure

Answers

Answer 1

Answer:

Answer: The potential of electrons in a circuit can be increased by the action of the battery.

Explanation:

A battery is a source of energy. It provides push to voltage so that the current can flow in the circuit.

For example, the electrical energy is used by the bulb connected in the circuit. The electrical energy is provided by the battery. If the energy of the battery is used up then no current will flow in the circuit. Then the bulb will not glow in this case.

Therefore, the potential of electrons in a circuit can be increased by the action of the battery.

Answer 2

Answer: The potential of electrons in a circuit can be increased by the action of a battery.

A wedge is simply a form of an inclined plane. TRUE or FALSE.

Answers

The statement about "A wedge is simply a form of an inclined plane" is false. The pivot joint is the lever and the wedge are the blades of the scissors. This is to efficiently exert force on an object to cut it.

A 1200 kg automobile is traveling at a velocity of 100 m/s is its energy potential or kinetic? How much energy does it possess?

Answers

The energy possess is 6,000,000 J

The kinetic energy is a energy by which an object can move and potential energy is a stored energy which depends upon the relative position of various parts of the body.

Given:

The mass of automobile is $m=1200\:\rm kg$ .

The velocity of the automobile is $100\;\rm m/s$ .

How to calculate potential energy and kinetic energy?

Write the formula to calculate the potential energy of the body.

$P.E=mgh$

Since the automobile is on ground so the height $h$ will be 0.

$P.E=1200* 9.81* 0\nP.E=0$

Write the formula to calculate the kinetic energy.

$K.E=(1)/(2)mv^2$

Substitute the value.

$K.E=(1)/(2)* 1200* 100^2\nK.E= 6,000,000 J.$

Answer:

6,000,000 J (6 million)

Explanation:

Refer to the equations for potential and kinetic energy.

$KE = (1)/(2)mv^(2)\nPE = mgh$

Because the automobile is on the ground (it does not give a height above the ground, therefore we can assume that it is on the ground), height = 0. If you plug in 0 for h in the potential energy equation, we get PE = 0 J.

Therefore, all of the energy is kinetic. Plug in the given information into the kinetic energy equation. M = 1200 kg and v = 100 m/s

$KE = (1)/(2)mv^(2) = (1)/(2)(1200)(100^(2)) = 6,000,000\ J$

Older auto-focus cameras sent out a pulse of sound and measured the time interval required for the pulse to reach an object, reflect off of it, and return to be detected. Can air temperature affect the camera's focus? New cameras use a more reliable infrared system.

Answers

Temperature is also a condition that affects the speed ofsound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. so the higher the air temperature the faster it will focus.
