The force of repulsion between two like-charged particles will increase ifA) the distance between the charged particles is increased.

B) the distance between the charged particles is decreased.

C) the magnitude of the charge on both the particles is decreased.

D) the magnitude of the charge on one of the particles is decreased.

Answers

Answer 1

Answer:

The force of repulsion between two like-charged particles will increase if the distance between the charged particles is decreased.

What is coulomb's law?

According to Coulomb's law: The magnitude of each of the electric forces with which two point-at-rest charges interact is directly proportional to the product of the magnitude of both charges

And inversely proportional to the square of the distance that separates them and has the direction of the line that joins them.

The formula will be given as:

$F=(kq_1q_2)/(r^2)$

We can see that the force is inversely proportional to the distance of the two charges.

The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf. t/f

Answers

Answer: The given statement is false.

Explanation:

Kinetic energy is defined as the energy obtained by an object because of its motion.

For example, moving a pulley on the road.

Whereas energy of an object obtained due to its position is known as potential energy.

For example, lifting a book from table to the shelf shows position of the book has changed.

Therefore, we can conclude that the statement kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf, is false.

The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf is false. The kinetic energy on the shelf is zero because it is not in action.

Which of the following correctly describes a solenoid? A) The magnetic field around a solenoid is unipolar.
B) The field around a solenoid is termed a bar magnet.
C) A solenoid is created by winding current carrying wire into a coil.
D) Increasing the current in the wires will reduce the magnetic field outside of the solenoid.

Answers

Answer;

C) A solenoid is created by winding current carrying wire into a coil.

Explanation;

-A solenoid is a coil of insulated or enameled wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron.

-Solenoids have a wide range of applications, for instance they are used as electromagnets, as inductors in electronic circuits, and as miniature wireless receiving antennas.

Option C describes a solenoid

In which state of matter do the particles spread apart and fill all the space available to them?a. crystal
b. liquid
c. gas
d. solid

Answers

The correct answer is c) gas.

In gases, in fact, particles are not bound together (and the intermolecular forces between them are negligible) and they are completely free to move. For this reason, when a gas is put in a container, the particles of the gas will move in every possible direction, filling all the space available in the container (for this reason, we also say that gases have no fixed shape).

Please help me! In a collision, Kara Less who was traveling at 11 m/s while texting in her 1300 kg car, is struck by another vehicle and finds herself and her phone suddenly moving 2.5 m/s in the opposite direction. What impulse does she experience? SHOW WORKAnswer Choices

A. -12,000
B. -14,000
C. -16,000
D. -18,000

Answers

Answer:

D. -18,000

Explanation:

Let's define impulse :

Impulse is defined as the product of Force ( N ) applied on the body and the time of impact ( s ) or
The change in momentum

hence in this question ,

kara is initially moving with the :

velocity $v_(i)$ = 11 $ms^(-1)$

finally moving with velocity $v_(f)$ = -2.5 $ms^(-1)$ (minus as she moves in the opposite direction )

therefore the initial momentum $p_(i)$ = $m*v_(i) = 1300*11 = 14300 kgms^(-1)$

and the final momentum $p_(f)$ = $m*v_(f) = 1300*-2.5= 3250 kgms^(-1)$

thus the change in momentum : $p_(f)$ - $p_(i)$

= -3250-14300 = -17550 $kgms^(-1)$ ≅ -18000 $kgms^(-1)$
