12 If pressure is applied to a rock until its volume is
mote1985 [20]

Answer: The correct answer to the question is option 2

If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.

Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.

Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.

Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.

This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.

Bob had a cyst removed from his liver. The doctor told him the liver cells would grow back and repair the area. These liver cell
Dmitry_Shevchenko [17]

Answer: The correct answer to the fill in the blank is Mitosis.

Mitosis is a type of cell division that results in the formation of two daughter cells having the same number of chromosomes as compared to their parent cell. Thus, by producing more number of identical cells, mitosis helps in the growth and repair of tissues.

Thus, after removal of cyst from the liver of Bob, the cells would grow and repair the area through mitosis.

An object has a kinetic energy of 32 J and a mass of 36 kg, how fast is the object moving?
marin [14]

Answer:

1.33 m/s

Explanation:

The formula for Kinetic Energy is given as:

K.E=\frac{1}{2} mv^{2} \\

Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.

Re-arranging the above equation and isolating v, we get

2 K.E = mv^{2}\\\\v^{2} = \frac{2 K.E}{m}

Putting values in this equation, we get:

v^{2}=\frac{2 \times 32}{36}\\\\ v^{2}=\frac{16}{9}\\\\ v=\frac{4}{3}\\\\  v=1.33

Thus, the object is moving with a velocity of 1.33 m/s
