Answer:

\boxed {\tt 944.748 \ grams}

Explanation:

The formula for density is:

d=\frac{m}{v}

Rearrange the formula for mass, m. Multiply both sides by v.

d*v=\frac{m}{v} *v

d*v=m

Mass is found by multiplying the mass by the volume.

The density of the gold is 19.32 grams per cubic centimeter. The volume is 48.9 cubic centimeters.

d= 19.32 \ g/cm^3 \\v=48.9 \ cm^3

Substitute the values into the formula.

m= 19.32 \ g/cm^3 *48.9 \ cm^3

Multiply. Note the centimeters cubed will cancel out.

m= 19.32 \ g * 48.9

m= 944.748 \ g

The mass of the gold is 944.748 grams.

Pierce conducts an experiment in which waves collide in a way that the energy increases, which means that has occurred
Vikki [24]
<h2>Answer:</h2>

It means the waves collides and constructive interference occurred.

<h3>Explanation:</h3>

If the two waves coming from the opposite direction collide with each other, there are two way of their interference.

  • Constructive interference: An interference which results in the increase in energy. And it is when crust of a wave comes on the crust of second wave.
  • Destructive interference: An interference which results in decrease in energy of the resulting wave and colliding waves cancel the result of each other.

Hence in experiment there will be constructive interference.
