The Statue of Liberty is composed of copper. The smallest particle of any amount of copper is A)
an atom.



B)
an element.



C)
a compound.



D)
a molecule.

Answers

Answer 1
Answer: Option A, because the atom is the smallest molecule, it is the smallest particle containing copper as part of the copper family, which are the best conductors of electricity and is a transition metal with atomic number. With this metal is composed the statue of liberty.

A bus travels 4 km due north and then 3 km due west goingfrom bus station A to bus station B. The magnitude of the bus'
displacement from station A to station B is __km

Answers

Here, we are required to find the magnitude of the bus

displacement from station A to station B.

The magnitude of the bus

displacement from station A to station B is 5km.

The magnitude of the displacement is the "distance between the starting position of a body or object and the end position of that body or object".

The bus moves 4kmnorth and then moves 3km west, forming a right triangle. Its displacement is therefore the length of the hypotenuse.

let

x = length of the hypotenuse.

x² = 3² + 4²

x² = 9 + 16

x² = 25

Then remove the square on x by adding square roots to both sides

√x² = √25

x = √25

x = 5

The magnitude of the bus's displacement from station A to station B is 5 km.

Explanation:

The magnitude of the displacement is the distance between the starting position and the end position.

The bus moves north, then west, forming a right triangle.  Its displacement is therefore the length of the hypotenuse.

x² = 3² + 4²

x = 5

The magnitude of the bus's displacement from station A to station B is 5 km.

What happens to the negative charges

Answers

Answer:

The correct option is C) spreads out over a large area on the object.

Explanation:

In physics, a ground can be described as a reservoir object in which charge can be stored. Grounding refers to the removal of charge in an object by using the ground object. When an object with excess if charge is placed on the ground object, the electrons are transferred from the charges object to the ground object. This charge begins to spread evenly in the ground object with the passage of time.

Fill in the blank. The gravitational attraction between two objects will ----------- if one object acquires more mass.

Answers

Well,

The Second Universal Law of Gravitation states that "The gravitational attraction between two masses is directly proportional to the mass of each individual object."  That means that if one object gains mass and the other object retains its mass, then gravitational attraction between them will increase.

So, the missing word is "increase."

That's easy.  Once we cut through all the scientific jargon,
we realize it's as simple as: 

A person's weight on Earth increases if he acquires more food,
or puts stones in his pockets.

Explanation:

When using the right-hand rule to determine the direction of the magnetic field around a current-carrying wire, which part of theright hand points in the direction of the magnetic field?

-palm
-fingers
-back
-thumb

Answers

Answer: Palm

Explanation: When you have a wire, you must point your thumb in the direction in which the electricity is going, and now you close your palm, in the direction in which you closed your hand is in the direction in which points the magnetic field.

Then the correct option is the first one, the palm points in the direction of the magnetic field.

Answer:

Fingers

Explanation:

The index finger shows the moving charge, while your middle finger shows the magnetic field line.
