Answer:

0.75 NC⁻¹

Explanation:

Electric field intensity ( or strength of the electric field ) is the force per a 1 C charge,

So, Force (F) = Electric field intensity(E) × Charge (q)

                 F = E×q ⇒ q = F/E

                                      = 4.5×10⁻⁴/6×10⁻⁴ = 0.75 NC⁻¹

According to cool om's law electric fields are generated due to charges. When charges are same there is a repulsive force acted on both charges. When charges are opposite there is a attraction force acted  on both charges.

According to cool om's law,

F =G×q1×q2 / r²

F = force exerted of two charges

q1 , q2 = charges

r = distance between two charges

And also Electric field intensity is a vector which has a magnitude and direction both. Direction is depending on a charge and the sign of the charge

A car is accelerated from 40 m/s to 48 m/s in 6.5 seconds. What is the magnitude of the car’s
pantera1 [17]

Answer:

Explanation:

AVerage acceleration is the cjange in velocity with time

a = v-u/t

v is the final velocity = 48m/s

u is the initial velocity = 40m/s

t is the time = 6.5s

a = 48-40/6.5

a = 8/6.5

a = 1.23m/s²

Hence the magnitude of the car’s  average acceleration during this period is 1.23m/s²

How does the sun transmit energy from millions of miles away into the Earth system? 'Energy' and 'power' are often confused, but
Leona [35]

Answer:

  • Energy from sun travels to the earth by radiation of waves.
  • Energy is the capacity to do the work whereas power is the rate of doing work or the rate of energy transfer.
  • Energy always transforms from higher grade to a lower grade.

Positive feedback are not good when it disturbs the stability too much over a wide range.

No, negative feedback are not always bad because they enhance the stability of our system, resist the change in a system making it consistent and have a narrower range of variation.

Explanation:

The energy from the sun travels a huge distance in vacuum and atmosphere.

  • The solar energy travels to the earth in the form of electromagnetic radiations which do not require any medium of transmission and are capable of travelling in vacuum by the mode called radiation. In this mode the packets of energy get directly transmitted from the source to its surroundings. This packet of energy is called quanta.
  • Energy is the capacity to do work. Everything that we see and feel around us is some sort of energy. Every matter is the condensed form of energy the other forms that we cannot touch or feel is the wave form of energy. The wave form of energy stays in two form either stored in a mass or it is in transition. Now the concept of power arises form the energy in motion, power is defined as the rate of doing work or the rate of energy transfer. We usually use the term power for the energy in motion.
  • We can burn a gallon of fuel only once because it undergoes a chemical change and the chemical changes are mostly permanent in nature. There is a certain direction to which the energy can  flow spontaneously. When we burn the fuel then the stored chemical energy of the fuel gets converted into heat and light and the heat energy released during the combustion of the fuel is sufficient to further provide the heat of combustion of fuel.
  • Energy always transforms from high grade to the lower grade and the converse is not possible spontaneously.

Positive feedback are not good when it disturbs the stability too much over a wide range.

No, negative feedback are not always bad because they enhance the stability of our system, resist the change in a system making it consistent and have a narrower range of variation.

Explain how respiration and photosynthesis are chemically opposite from each other
NeTakaya
They are chemically opposite in that the reactants of one are the products of the other. One could not exist without the other to supply the materials. 

You can look up the reactants and products in any Biology textbook. also <span>In Photosynthesis carbon dioxide and energy is consumed to give sugar and Oxygen. </span>
<span>while in Respiration oxygen and sugar is consumed to give energy and carbon dioxide is produced. </span>

<span>Hence the two are opposite of each other. </span>

<span>Now, since you need oxygen to respire there must be a constant supply of oxygen and plants are the source of oxygen since they produce oxygen due to photosynthesis, similarly plants need oxygen to do photosynthesis which is produced by respiration. </span>

<span>Hence they both are dependent on each other   HOPE IT HELP ;D</span>
