Answer:

Equivalent resistance of this circuit is 1.6 ohms.

Explanation:

In the given figure, the three resistors are connected in parallel with 12 Volt battery. In parallel combination of resistors, the potential difference across each resistor is same but the current across each resistors divides.

The equivalent resistance is given by :

\dfrac{1}{R_p}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+\dfrac{1}{R_3}

Here, R₁ = 3 ohms, R₂ = 6 ohms and R₃ = 9 ohms

\dfrac{1}{R_p}=\dfrac{1}{3}+\dfrac{1}{6}+\dfrac{1}{9}

R_p=1.6\ \Omega

Hence, the equivalent resistance of this circuit is 1.6 ohms.

Mashcka [7]

Explanation:

P.E=MGH

(1) P.E=5×10(G)×3

= 150 kg m^/s^ ( ^ =sqaure)

(2) P.E=5×10×6

= 300 kg m^/s^

Hope it helps, just remember the formula u can solve any question regarding gravition of earth (P.E=Mgh)

A train moving at 5 m/sec passed a track gang and then accelerated uniformly a rate of 1.2 m/sec/sec for 5 min. How far did the
Amanda [17]

Answer:

S = V0 t + 1/2 a t^2

S = 5 m/s * 300 s + 1/2 * 1.2 m/s * (300 s^2)

S = 1500 m + .6 * 90000 m = 55,500 m

Check:     V0 = 5 m/s

                V2 = V0 + a t  = 5 + 1.2 * 300 = 365 m/s

Vav = (V1 + V2) / 2 = (5 + 365) / 2 = 185 m/s     (note uniform motion)

S = 185 * 300 = 55,500 m

We calculated V2 above at 365 m/s  the speed after 300 sec

Explain Newtons Laws​
Vsevolod [243]

1) <u>Newton</u><u> </u> <u>first</u><u> </u> <u>law</u><u> </u><u>of</u><u> </u><u>motion</u>: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”

This law also called <u>law</u><u> </u><u>of</u><u> </u><u>inertia</u><u> </u><u> </u>

2)<u> </u><u>Newton</u><u> </u><u>second</u><u> </u><u>law</u><u> </u><u>of</u><u> </u><u>motion</u><u>:</u><u> </u>states that ‟acceleration to the force acting on the body and inversky proportional to the <u>mass</u><u> </u> of the body”

3)<u> </u><u>Newton's third law of motion</u><u>:</u> It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.

These forces are called <u>action</u><u> </u> and <u>reaction</u><u> </u> forces

hope it's helpful ❤❤❤❤❤❤

The moon has a smaller mass than the Earth. If
ArbitrLikvidat [17]

Answer:

Decrease

Explanation:

If you were on the Moon, which has significantly less mass than the Earth, your weight would: decrease

The point that seemed to be giving me a complicated time was being able to distinguish the difference and meaning of weight and mass and being able to apply that to a problem. I kept mixing up the definitions. For example in homework 3.1, one question asked:

If you were on the moon, which has significantly less mass than the earth, your mass would:

a. increase

b. decrease

c. stay the same

d. become zero

The definition of mass is the amount of matter in an object. The definition of weight is the amount or unit of force. For me, I just had to remember that when it asked about weight, it wasn’t referring how heavy an object is. After I was able to recognize that when it came to weight, questions became easier.

The final and correct answer was decreasing. The answer is because the Moon’s mass is less. This means the gravitational force is less on your body, therefore, your mass is going to be lighter

Plane polarized light with intensity I0 is incident on a polarizer. What angle should the principle axis make with respenct to t
Nataliya [291]

Answer:

 Q = 47.06 degrees

Explanation:

Given:

- The transmitted intensity I = 0.464 I_o

- Incident Intensity I = I_o

Find:

What angle should the principle axis make with respect to the incident polarization

Solution:

- The relation of transmitted Intensity I to to the incident intensity I_o on a plane paper with its principle axis is given by:

                                     I = I_o * cos^2 (Q)

- Where Q is the angle between the Incident polarized Light and its angle with the principle axis. Hence, Using the relation given above:

                                     Q = cos ^-1 (sqrt (I / I_o))

- Plug the values in:

                                     Q = cos^-1 ( sqrt (0.464))

                                     Q = cos^-1 (0.6811754546)

                                     Q = 47.06 degrees
