A device that uses electricity and magnetism to create motion is called a _________motor,magnet,generator . In a reverse process, a device that uses motion and magnetism can be used to create ________ light,electromagnetism,electricity

Answers

Answer:

1. motor

2. electricity

Explanation:

A motor uses electromagnetism or electricity and magnetism to create motion. A motor converts electric energy into mechanical energy.

On the other hand, the reverse process of using motion and magnetism will create electricty. It will convert the mechanical energy to electrical energy. And the machine that does it is called a generator.

A device that uses electricity and magnetism to create motion is called a "Motor" (which converts electric energy into mechanical energy) & In a reverse process, a device that uses motion and magnetism can be used to create "Electromagnetism".

In short, 1st Blank = Motor

Ions are atoms of the same element that have a different number of _____________.Question 13 options:

A. nuclei


B. nucleons


C. electrons


D. protons


E. neutrons

Answers

The correct option is C.

How do an atom and an ion of the same element differ?

Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

What makes different ions of the same element different?

An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

Gravitational pull must be measured in units of

Answers

Gravitational force must be measured in units of : meters per second squaredIn every Physics equation, usually the amount of Gravitational force is standardized and will be exactly the same as long as the event happens on the earth, which is 9.8 m/s^2.

The direction of the pull is -70.93°, or approximately 71° South of West.

Given the vector as F= (−2980.0i^ + 8200.0j^)N

The magnitude of the pull is given by the formula below:

Magnitude of pull,  |F| = √(F_x^2 + F_y^2)

Here, F_x is the force in the x-direction and F_y is the force in the y-direction. We know that:

F_x = -2980.0 N and F_y = 8200.0 N

Therefore, the magnitude of the pull is:

|F| = √(F_x^2 + F_y^2)|F| = √((-2980.0)^2 + (8200.0)^2)|F| = √(88840000) |F| = 9425.89 N

The direction of the pull can be found as follows:

θ = tan⁻¹(F_y/F_x)θ = tan⁻¹(8200.0/-2980.0)θ = -70.93°

The direction of the pull is -70.93°, or approximately 71° South of West.

At a certain location, the earth's magnetic field has a magnitude of 5.7×10−5 t and points in a direction that is 73 ∘ below the horizontal. part a find the magnitude of the magnetic flux through the top of a desk at this location that measures 81 cm by 85 cm

Answers

Answer:

1.15 * 10^(-5) Tm²

Explanation:

Parameters given:

Magnitude of magnetic field, B = 5.7 * 10^(-5) T

Angle of magnetic field to the horizontal plane = 73°

Dimension of the desk = 81 cm × 85 cm

Area of desk, A = 6885 cm² = 0.6885 m²

The magnitude of the Magnetic Flux, |Φ|, is given as:

|Φ| = |B * A * cosθ|

Where θ = angle of the Magnetic field to the normal of the desk = 90 - 73 = 17°

Therefore, the magnitude of the Magnetic Flux will be:

|Φ| = |5.7 * 10^(-5) * 0.6885 * cos17|

|Φ| = 3.75 * 10^(-5) Tm²

When the magnitude of the magnetic flux through the top of a desk at this location is = 1.15 * 10\wedge (-5) Tm2

Calculate of Parameters

Parameters as per the question given:

Then The Magnitude of the magnetic field, B = 5.7 * 10\wedge (-5) T

Then, The Angle of the magnetic field to the horizontalplane = 73°

After that, The Dimension of the desk = is 81 cm × 85 cm

Now, The Area of desk, A = 6885 cm² = 0.6885 m²

When The magnitude of the Magnetic Flux, |Φ|, is given as:

Then, |Φ| = |B * A * cosθ|

Where θ is = angle of the Magnetic field to the normal of the desk = 90 - 73 = 17°

Thus, the magnitude of the Magnetic Flux will be:

|Φ| =|5.7 * 10\wedge (-5) * 0.6885 * cos17|

|Φ| =3.75 * 10\wedge (-5) Tm²

The quantum mechanical model of the atom ____. a. defines the exact path of an electron around the nucleus b. was proposed by Niels Bohr c. involves finding an electron somewhere in a specific orbital d. has many analogies in the visible world

Answers

Answer:

Quantum mechanical model = involves finding an electron somewhere in a specific orbital.

Explanation:

The quantum mechanical model of an atom involves finding an electron somewhere in a specific orbital. This method is completely based on mathematical calculations. It defines the probability of finding an electron rather than its reality.

These are designated by some letters like s, p, d, f...... and the corresponding energy levels are 1st, 2nd, 3rd and so on.....

So, the correct option is (c) "involves finding an electron somewhere in a specific orbital".
c. involves finding an electron somewhere in a specific orbital
