What are electron orbitals

Answers

Answer:

Electron orbitals are energy levels or shells that an electron inhabits in an atom or a molecule. The number of orbitals in an atom depends on the number of protons in its nucleus. The electrons fill the orbitals from lowest to highest energy. The arrangement of electrons in the orbitals determines the behavior and properties of the atoms and molecules.

The force between two magnetic poles will increase as their separation is increased. true or false?

Answers

False, because the force between two charged objects decreases as distance between them increases, as per the universal magnetic force law: 

F = kq1q2 / r^2, where F is the force, r is the distance between the objects, k is the universal magnetic constant, and q1 and q2 are the unit charge per unit mass values, 

Which explains how the Coriolis effect causes air circulation? A.
Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer west. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the east.
B.
Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the west.
C.
Air from the poles moves toward the equator faster than the ground below it, so friction causes the air to veer east. In contrast, air from the equator moves toward the poles slower than the ground below it, so friction causes it to veer to the west.
D.
Air from the equator moves toward the poles slower than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator faster than the ground below it, so friction causes it to veer to the west.

Answers

The right answer for the question that is being asked and shown above is that: "Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer west. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the east. "

A tiger runs one kilometer. The tiger does 15,000 J of work and has a total power output of 500 W. How many minutes does it take the tiger to run the distance? (Points : 3)0.30 sec
30 sec
3.0 sec
300 sec

Answers

Power is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. The formula would be as follows:

P = W/t 

We calculate as follows:

500 W = 15000 J / t
t = 30 s

Which particle would produce a magnetic field?(1) a neutral particle moving in a straight line
(2) a neutral particle moving in a circle
(3) a stationary charged particle
(4) a moving charged particle

Answers

Answer: The correct answer is "a moving charged particle".

Explanation:

If the current flowing in the conductor then there is magnetic field around the wire which can be detected by the compass needle.

Here, the flow of charges which are negatively charged electrons produces the magnetic field. The flow of charges constitutes the electric current.

If there is no flow of the charged particles then there is no magnetic field produce. To produce magnetic field, it is necessary that charged particle must move.

From the given options, a moving charged particle would produce a magnetic field.

Therefore, the correct option is (4).
Neutral particles and stationary charged particles
don't produce magnetic fields. 

Charged particles in motion do.
