The density of the gold is 19.3g/cm3.
elena55 [62]

If both nuggets have the same mass and different densities then it can be concluded that the volume with the highest density is smaller.

For, so to speak, density is a relation of how much mass is there in a given volume. So the more the mass and the smaller the volume, the greater the density.

To verify this, let us calculate the volumes of iron pyrite and gold pyrite.

For the iron pyrite nugget:

density = mass / volume

volume = mass / density

volume = 50/5

volume = 10cm3


For the gold nugget:

volume = mass / density

volume = 50 / 19.3

volume = 2.59cm3


Therefore it is found that the nugget with the highest density (gold) is the one with the lowest volume.

What is the net force? <br><br> URGENT! thank you
alexandr402 [8]
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.

You connect a 9V battery to a capacitor consisting of two circular plates of radius 0.066 m separated by an air gap of 2.0 mm. W
mel-nik [20]

The charge on the positive plate is 1.734*10^{-12} C

Given,

V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85*10^{-12}

We know C=∈ * \frac{A}{G}= 8.85*10^{-12} *\frac{\pi *0.066^{2} }{0.002}=19.275*10^{-12} F

Also, Q = C V = 19.275*10^{-12} * 9 = 1.734*10^{-12} C

<h3>Charge </h3>

When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. A charge on an electric field might be positive or negative. Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Electric charge is a conserved property; in an isolated system, the net charge, or the sum of the positive and negative charges, is constant. Subatomic particles transport electrical charge. The protons in atoms' nuclei carry positive charge in normal matter, while the electrons carry negative charge.
