Which statement is the correct representation of these electric field lines?

Physics

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>

Professional Application. A 96 kg football player catches a 0.900 kg ball with his feet off the ground with both of them moving
Zarrin [17]

To solve this problem it is necessary to apply the equations related to the conservation of momentum.

This definition can be expressed as

m_1u_1+m_2u_2 = (m_1+m_2)V_f

Where

m_{1,2} = Mass of each object

u_{1,2} = Initial Velocity of each object

V_f= Final velocity

Rearranging the equation to find the final velocity we have,

V_f = \frac{m_1u_1+m_2u_2}{(m_1+m_2)}

Our values are given as

m_1 = 96Kg\\m_2 = 0.9Kg\\u_1 = 6.3m/s\\u_2 = 27.4m/s

Replacing we have,

V_f = \frac{(96)(6.3)+(0.9)(27.4)}{(96+0.9)}

V_f = 6.4959m/s

Therefore the final velocity is 6.5m/s

B. On a separate sheet of paper, describe the different ways of generating electric power. ​
Afina-wow [57]

Answer:

These all different sources of energy add to the store of electrical power that is then sent out to different locations via high powered lines. It is the energy from the sun that is harnessed using a range of technologies such as solar heating, solar architecture, photovoltaics, and artificial photosynthesis.

How much heat is needed to boil 120 kg of water ?
nekit [7.7K]
Q = mc<span>∆t, where:
q = energy flow
m = mass, 120 000 g
c = specific heat capacity, 4.81 J/gC
</span><span>∆t = change in temperature, ~75 (100 - 25, which is room temperature)

Substituting in the values, we get:
q = 120000 x 4.81 x 75 = 43290000 Joules = 43.29 MJ

Hope I helped!! xx
