Answer:

C. Source A is negatively charged and source B is positively charged.

Explanation:

As per the properties of electric field lines we know that electric field lines originated out from the positive charge and then terminated back into the negative charge.

As per the given presentation of field lines we can see that field originated out from charge placed at B and these field lines again terminated into the charge placed at A.

So here the charge must be positive at position of B and it is negative at position of A.

so correct answer will be

C. Source A is negatively charged and source B is positively charged.

Note that the electric field lines begin from the higher voltage to the lower

Because the negative pole is lower voltage than the positive pole

The lines go out the positive charges and go in the negative charges

Then, the correct statement is:

<u>C. Source A is negatively charged and source B is positively charged.</u>

sukhopar [10]

Answer:

0.025 A

Explanation:

A = 50 cm^2 = 50 x 10^-4 m^2

B2 = 6 T, B1 = 2 T

db = 6 - 2 = 4 T

dt = 2 s

R = 0.4 ohm

Let i be the magnitude of induced current and e be the induced emf.

According to the Faraday's law of electromagnetic induction

e = dФ / dt

e = A dB / dt

e = 50 x 10^-4 x 4 / 2 = 0.01 V

i = e / R = 0.01 / 0.4 = 0.025 A

What is this feature?
Viktor [21]

Answer: c Delta

Explanation:

A delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.

Hope this helps!!

How much energy is required to accelerate a golf ball of mass 0.046 kg initially at rest to a speed of 0.75c?
Andrew [12]

The required energy to accelerate the golf ball is  0.232875X10^{16} kg-m/sec^2.

<h2>What is Energy?</h2>
  • Energy, which is observable in the execution of labor as well as in the form of light and heat, is the quantitative quality that is transmitted to an object or to a physical phenomenon in physics.
  • Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.
  • The joule, which is defined as "the energy transmitted to an object by the effort of moving it a length of one metre against a force of one newton," is the standard measure for power in the International System of Units (SI).

Given that,

E=mc^2

=0.046X0.75^2Xc^2

=0.232875X10^{16} kg-m/sec^2 .
