8 0

Answer:

816.33 kg

Explanation:

To solve this problem we'll need to keep in mind the <em>formula for the kinetic energy of an object</em>:

  • E = 0.5 * m * v²

Where E is the kinetic energy, m is the object's mass and v its velocity.

We<u> input the data given by the problem</u>:

  • 500000 J = 0.5 * m * (35 m/s)²

And <u>solve for m</u>:

  • m = 816.33 kg

Taking into account the definition of density, the density of the sample is 0.5 \frac{g}{mL}.

It is necessary yo know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density allows you to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

In this case, you know:

  • mass= 6 g
  • volume= 12 mL

Then, replacing in the definition of density:

density=\frac{6 g}{12 mL}

Solving:

<u><em>density= 0.5 </em></u>\frac{g}{mL}<u><em /></u>

Finally, the density of the sample is 0.5 \frac{g}{mL}.

A stream of negatively charged particles is called:
AlladinOne [14]
Cathode rays are a stream of negatively charged particles or electrons in vacuum tubes. They were first seen by Johann Hittorf in 1869. They are named since they are emitted by electrode or cathode. In order to release the electrons, the electrons should first be detached from the atoms of the cathode.
