F. A 50. A resistor (R2), and unknown resistor R2, a 120 Volt source, and an ammeter are connected in a
complete circuit. The ammeter reads 0.50 ampere (current).
R1
a. Determine the resistance of Rz.
R2

Answers

Complete question is;

A 50.-ohm resistor, an unknown resistor R, a 120-volt source, and an ammeter are connected in a complete circuit. The ammeter reads 0.50 ampere.

A) Calculate the equivalent resistance of the circuit shown.

B) Determine the resistance of resistor R shown in the diagram.

Answer:

A) R_eq = 240 Ω

B) R = 190 Ω

Explanation:

A) To get the equivalent resistance, we will use the formula;

R = V/I

Where;

V is Voltage

I is current

R is equivalent resistance

From the question, V = 120 V and I = 0.5A

Thus;

R_eq = 120/0.5

R_eq = 240 Ω

B) From the image, we see that the resistors are connected in series.

Formula for resistors in series is;

R = R1 + R2 +..... Rn

Thus;

240 = 50 + R

R = 240 - 50

R = 190 Ω

A) The equivalent resistance of the circuit shown will be  240 Ω.

B) The resistance of resistor R will be 190 Ω

What is resistance?

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The given data in the problem is;

R is the resistance = 50.-ohm

v is the voltage = 120-volt source

I is the value of the current =0.50 ampere.

A) The equivalent resistance of the circuit shown will be  240 Ω.

According to ohm's law

[tex]\rm R= \frac{V}{I} \\\\ \rm R= \frac{120}{0.5} \\\\ \rm R=240 \ ohm[/tex]

Hence the equivalent resistance of the circuit shown will be 240 Ω.

B) The resistance of resistor R will be 190 Ω

The given resistors are connected in the series;

R = R1 + R2 +..... Rn

240 = 50 + R

R = 240 - 50

R = 190 Ω

Hence the resistance of resistor R will be 190 Ω

The voltage across the terminals of a generator is 5.7 v when it supplies a current of 0.3 A. It becomes 5.1 V when I=0.9A. Find its emf and it's internal resistance

Answers

Answer:

The emf of the generator is 6VThe internal resistance of the generator is 1 Ω

Explanation:

Given;

terminal voltage, V = 5.7 V, when the current, I = 0.3 A

terminal voltage, V = 5.1 V, when the current, I = 0.9 A

The emf of the generator is calculated as;

E = V + Ir

where;

E is the emf of the generator

r is the internal resistance

First case:

E = 5.7   + 0.3r -------- (1)

Second case:

E = 5.1 + 0.9r -------- (2)

Since the emf E, is constant in both equations, we will have the following;

5.1 + 0.9r = 5.7   + 0.3r  

collect similar terms together;

0.9r - 0.3r = 5.7 - 5.1

0.6r = 0.6

r = 0.6/0.6

r = 1 Ω

Now, determine the emf of the generator;

E = V + Ir

E = 5.1 + 0.9x1

E = 5.1 + 0.9

E = 6 V

Two statements, that describe what happens in both nuclear fusion and nuclear fission reactions, are:

Radiation is released from the nuclei that undergo a reaction.A small amount of the mass in each nucleus that undergoes a reaction is converted to energy.

Hence, option (C) and (D) are correct.

What is nuclear reaction?

A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.

What happens to the force between charged and uncharged objects as the distance between them decreases?

Answers

Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.

Hope this helps have a awesome night/day❤️✨

Explanation:

Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.

(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)

So a better question would then be, what is gravity’s relationship with an electric field?

You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)

Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).
