Traelling at this much velocity is impossible. So this situation is impossible.

<h3>What is called a circular?</h3>
  • A circular is just a letter that is circulated widely and contains some crucial information. A circular will be the most effective form of communication if, for instance, you need to amend the dress code for the entire workplace or invite an entire department to a conference.
  • A leaflet or newspaper supplement is referred to as a "circular" since its original purpose was for it to circulate—to pass among a group of people. According to the Oxford English Dictionary, the word was created in the early 19th century as a shortened version of the much older term "circular letter."
  • What circular actually implies. Being circular with your economy means you have purposefully returned the excess or waste your company produces to the sourcing track. Anything from raw materials used in production to concepts developed during a brainstorming session might be used in this way.

Why is the following situation impossible?

The velocity of the body moving around the earth,v=sqrt(Gm/r)

G=6.67*10-11 Nm2/kg2

m=mass of the Earth

r=radius of the Earth=6.38*106m

Substituting we get,v=7906 m/s*60=474410 m/hr

Traelling at this much velocity is impossible. So this situation is impossible

Explain how a step-down transformer makes electricity safe for use in homes.
Savatey [412]

Answer:

it lowers the voltage in homes

Explanation:

this is due to safety reasons as a human cant survive power line voltages which are between 150k and 760k and if you plugged anything short of a piece of 1 inch thick wire not counting insulation it would immediately start smoking and burn the cable.

On your first day at work as an electrical technician, you are asked to determine the resistance per meter of a long piece of wi
Lostsunrise [7]

Answer:

0.06\Omega/m

Explanation:

Firstly, when you measure the voltage across the battery, you get the emf,

E = 13.0 V

In order to proceed we have to assume that the voltmeter offers no loading effect, which is a valid assumption since it has a very high resistance.

Secondly, the wires must be uniform. So the resistance per unit length is constant (say z). Now, even though the ammeter has very little resistance it cannot be ignored as it must be of comparable value/magnitude when compared to the wires. This is can seen in the two cases when currents were measured. Following Ohm's law and the resistance of a length of wire being proportional to it's length, we should have gotten half the current when measuring with the 40 m wire with respect to the 20 m wire (I=\frac{V}{R}). But this is not the case.

Let the resistance of the ammeter be r

Hence, using Ohm's law we get the following 2 equations:

\frac{13}{20z+r} =7.6   .......(1)

\frac{13}{40z+r} =4.5     ......(2)

Substituting the value of r from (2) in (1), we have,

13=152z+7.6\times\frac{13-180z}{4.5}

which simplifying gives us, z=0.0589\Omega/m\approx0.06\Omega/m (which is our required solution)

putting the value of z in either (1) or (2) gives us, r = 0.5325 \Omega
