Johanna makes the table below to organize her notes about centripetal forces. Which type of force should she place in the cell m
Valentin [98]

<u>Answer:</u> The correct answer is Option 2.

<u>Explanation:</u>

Centripetal force is defined as the force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.

Mathematically,

F_c=\frac{mv^2}{r}

Where,

F_c = centripetal force

m = mass of the object

v = tangential velocity

r = radius of the path

From the above relation, X corresponds to the radius and Y corresponds to the tangential velocity.

Hence, the correct answer is option C.

A block of metal has a mass of 0.0694 kg. It displaces 3.6 mL of water. What is it’s density in g/cm^3
Ivan

Answer:

19.28 g/cm^3 to the nearest hundredth.

Explanation:

The volume of water displaced = the volume of the metal.

density = mass / volume

0.0694 kg = 0.0694 * 1000

=  69.4 g.

Density = 69.4 / 3.6

= 19.28 g/cm^3.
