A parallel circuit is constructed with three different branches. An ammeter is placed in each of the branches to measure the bra

nch currents. An ammeter is also placed outside the circuit to measure the current in the voltage source.
If I1 = 2.8 A, I2 = 4.1 A, and I3 = 4.8 A, then what is the current in the battery (I_battery)?

Answer:

Current in the battery will be 11.7 A

Explanation:

We have given that the there is parallel circuit with three different branches.

Current in each branch is I_1=2.8A, I_2=4.1A,I_2=4.8A

We have to find the current I in the battery

It is known that in parallel circuit current is sum of current in each branches

So current in the battery will be equal to

I=I_1+I_2+I_3

I=2.8+4.1+4.8=11.7A

Therefore current in the battery will be 11.7 A

In a television picture tube, electrons strike the screen after being accelerated from rest through a potential difference of 27
Vera_Pavlovna [14]

Answer:

9.74 x 10^7 m/s

Explanation:

V = 27000 V

energy of electrons = e x V

K = 1.6 x 10^-19 x 27000 = 43200 x 10^-19 J

Energy = 1/2 m v^2

43200 x 10^-19 = 0.5 x 9.1 x 10^-31 x v^2

v^2 = 9.495 x 10^15

v = 9.74 x 10^7 m/s

A positive charge is placed midway between two equal negative charges. what is the direction of the total force on the positive
iragen [17]

The total force is the vector sum of the individual forces. The force from either electron has the same magnitude at the midpoint, but the directions of the forces are opposite, so the sum of the two forces is zero. I hope this helps! Thanks

PLEASE HELP !!! ASAP I WILL GIVE BRAINLIEST !!!
Paladinen [302]

Answer:

2.11 m

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 4.76 Kg

Initial velocity (u) = 0 m/s

Final velocity (v) = 6.5 m/s

Height (h) =?

NOTE: Acceleration due to gravity (g) = 10 m/s²

The height of the refrigerator can be obtained as follow:

v² = u² + 2gh

6.5² = 0² + (2 × 10 × h)

42.25 = 0 + 20h

42.25 = 20h

Divide both side by 20

h = 42.25 / 20

h = 2.11 m

Therefore, the refrigerator is 2.11 m high

An aseroid with a mass of 8.4x10^8 kg and a planet with a mass of 6.2x10^23 kg come close to each other by a distance of 8x10^5
N76 [4]

So, the force of gravity that the asteroid and the planet have on each other approximately

\boxed{\sf{5.43 \times 10^{10} \: N}}

<h3>Introduction</h3>

Hi ! Now, I will help to discuss about the gravitational force between two objects. We already know that <u>gravitational force occurs when two or more objects interact with each other at a certain distance and generally orbit each other to their center of mass</u>. For the gravitational force between two objects, it can be calculated using the following formula :

\boxed{\sf{\bold{F = G \times \frac{m_1 \times m_2}{r^2}}}}

With the following condition :

  • F = gravitational force (N)
  • G = gravity constant ≈ \sf{6.67 \times 10^{-11}} N.m²/kg²
  • \sf{m_1} = mass of the first object (kg)
  • \sf{m_2} = mass of the second object (kg)
  • r = distance between two objects (m)

<h3>Problem Solving</h3>

We know that :

  • G = gravity constant ≈ \sf{6.67 \times 10^{-11}} N.m²/kg²
  • \sf{m_1} = mass of the first object = \sf{8.4 \times 10^8} kg.
  • \sf{m_2} = mass of the second object = \sf{6.2 \times 10^{23}} kg.
  • r = distance between two objects = \sf{8 \times 10^5}

What was asked :

  • F = gravitational force = ... N

Step by step :

\sf{F = G \times \frac{m_1 \times m_2}{r^2}}

\sf{F = 6.67 \times 10^{-11} \times \frac{8.4 \cdot 10^8 \times 6.2 \cdot 10^{23}}{(8 \times 10^5)^2}}

\sf{F = \frac{347.374 \times 10^{-11 + 8 + 23}}{64 \times 10^10}}

\sf{F \approx  5.43 \times 10^{20 - 10}}

\boxed{\sf{F \approx 5.43 \times 10^{10} \: N}}

<h3>Conclusion</h3>

So, the force of gravity that the asteroid and the planet have on each other approximately

\boxed{\sf{5.43 \times 10^{10} \: N}}
