Imagine you are mpho:how can you help your friend (phenyo) not to be influenced by media? you really feel she needs some help be
LUCKY_DIMON [66]

One of the ways to help someone not to be influenced by media is:

  • Encourage independent thinking.
  • Let her know that she should make sure the information she is consuming is free from bias and is factual.

<h3>What is Media Influence?</h3>

This refers to the effects and reactions which the mass media has on the people who listen to them by shaping their views and by controlling the narrative.

With this in mind, we can note that if a person is overtly influenced by the media, then such a person lacks independent thinking and becomes emotional by what he watches on the television or reads from an online source.

This can be changed through the encouragement of independent thinking, and the need to check for factual information from the media news and also to focus more on studies.

What current is taken by the lamp when it is connected to a 220 v mains supply? what is the resistance of the lamp
eimsori [14]

Answer:

Given parameters

Potential difference (V) = 220 V

Power of lamp 1 (P1) = 100 W

Power of lamp 2 (P2) = 60 W

Both the bulbs are connected in parallel. Therefore, the potential difference across each of them will be 220 V, because no division of voltage occurs in a parallel circuit.

We know that

Power = Voltage x Current

P = V x I

I = P/V

Lamp 1:

I1 = P1/V

I1 = 100/220

I1 = 5/11 A

Lamp 2:

I2 = P2/V

I2 = 60/220

I2 = 3/11 A

Net current (I) = I1 + I2

I = 5/11 + 3/11

I = 8/11

I = 0.7273 A

Hence, current drawn from the line is 0.727 A

If 2.0 j of work Is done raising a 180 g Apple how far was it lifted
andrew11 [14]

The apple is lifted by 1.1 m

<u>Explanation</u>:

  • Given that, mgh = 2 J and mass of apple = 180g
  • Step 1: convert grams to kg as work is given in SI units.

                    180 g = 0.18 kg

  • Step 2: substitute in the formula for work done.

                    0.18 * 10 * h = 2

  • Step 3: calculate the value of h from this formula.

                      h = 2/1.8

                      h = 1.11 m

Higher Current = ________ Moving Electric Charges (Electrons) *
Eva8 [605]

Answer:

Higher current is normally achieved by faster moving electrons.

Explanation:

  • Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
  • Current is the net charge flowing per unit time.
  • Current can be represented by:

            I=v×e×N×A

where,

                  I= current

                  e= electric charge

                  v= speed of electrons

                  N=no. of free electric charges per volume

  • The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
