attashe74 [19]4 years ago
5 0

Answer:

Nothing

Explanation:

If you increase the amount of the substance you have, the density of it doesn't change because it's not the nature of the substance which changes, but the quantity of it. For example. If you have 1 lt of water or 3 lts. the density of the water still being the same, what changes is the amount of the substance.

20 points plz help i dont really understand how to do this

\huge{ \mathfrak{  \underline{ Answer} \:  \:  ✓ }}

1. Calculate the equivalent resistance in the circuit :

In the given diagram, the resistors are in series connection,

So equivalent resistance = sum of resistance of both resistors.

\large \boxed{R_{eq} =R_1 +R_2  }

  • R_{eq} =  480 + 360

  • R_{eq} = 840 \: ohms

Therefore, Equivalent resistance = 840 ohms.

2. Calculate the current through the battery :

\boxed{ \mathrm{current =  \dfrac{potential \:  \: difference}{resistance} }}

  • i =  \dfrac{120}{840}

  • i =  \dfrac{1}{7}

  • i = 0.142 \: Amperes

Hence, current through the battery = 0.142 A

3. How much current is passing through each resistor :

Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

A researcher is using a particle accelerator in an experiment studying isotopes. How can the researcher change one isotope into
Illusion [34]
The researcher can change one isotope into a different isotope of the same element by ADDING OR REMOVING NEUTRONS.
Isotopes refers to two or more forms  of the same element, which have the same number of protons but different number of neutrons. The difference in the number of neutrons of a particular element is what brings about isotopes, thus, isotopes can be created by removing  or adding neutrons to a particular element.<span />
