A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?

Answers

Answer 1

Answer:

Explanation:

Volume of cube=side³

=2*2*2

=8 cm³

Mass of cube=40g

Its density=mass/volume

=5g/cm³

which differs the value given in the text hence it is not gold and u should not bye it...

Instead u should call the police for arresting the person lol...

Answer 2

don’t buy it it’s not gold :)

Answer:

Net Force = 390 N

Explanation:

Net Force = is the sum of all forces acting on an object.

450 N - 60 N = 390 N

The net force acting on the buggy is 390 N pointing to the right.

What is force?

In physics, force is defined as: the push or pull on a mass that causes it to change velocity.

A force is an external agent that can change the state of rest or motion of a body. It has a magnitude as well as a direction. The direction of the force is the point where force is applied, and the application of force is the point where force is applied.

A spring balance can be used to calculate force. Newton is the SI unit of force.

A short blue arrow over the cart is labeled [tex]F_f[/tex] = 60 N

And A long blue arrow over the horse is labeled [tex]F_P[/tex]= 450 N.

Hence, The net force acting on the buggy is = 450 N - 60 N = 390 N pointing to the right.
