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

A spaceship is moving away from Earth at 0.892c when it fires a small rocket in the forward direction at 0.426c relative to the
Ipatiy [6.2K]

Answer:

The rocket's speed relative to Earth is 2.25\times10^{8}\ m/s.

Explanation:

Given that,

Speed of spaceship = 0.892c

Speed  of rocket = 0.426c

We need to calculate the rocket's speed relative to Earth

Using formula of relative speed

v=\dfrac{v_{s}-v_{r}}{1-(\dfrac{v_{r}v_{s}}{c^2})}

Put the value into the formula

v=\dfrac{0.892c-0.426c}{1-(\dfrac{0.892c\times0.426c}{c^2})}

v=c\dfrac{0.892-0.426}{1-0.379992}

v=c\times0.7516

v=2.25\times10^{8}\ m/s

Hence, The rocket's speed relative to Earth is 2.25\times10^{8}\ m/s.

A 4.0-cm tall light bulb is placed at distance of 8.3 cm from a concave mirror having a focal length of 15.2 cm. Determine the i
scoundrel [369]

Answer: the image distance is -18, 28 cm this means behind of the concave mirror. The image size is 2.2 higher that the original  so it has 8.8 cm with the same orientation as original  and it is a virtual imagen.

Explanation: In order to sove the imagen formation for a concave mirror we have to use the following equation:

1/p+1/q=1/f  where p and q represents the distance to the mirror  for the object and imagen, respectively. f is the focal length for the concave mirror.

replacing the values we obtain:

1/8.3+1/q=1/15.2

so 1/q=(1/15.2)-(1/8.3)=-54.7*10^-3

then q=-18.28 cm

The magnification is given by M=-q/p=-(-18,28)/8.3= 2.2

We also add a picture to see the imagen formation for this case.

A current of 0. 82 a flows through a light bulb. how much charge passes through the light bulb during 94 s?
gladu [14]

A current of 0. 82A flows through a light bulb. The charge passed through the light bulb during 94 s is 77.08C

The amount of charge flown for a given period of time determines the current passed through a bulb or electrical body.

The relation between the charge, current and time is given as:

Q = I × t

where, Q is the charge flown through bulb

I is the current passed through bulb

t is the time for which charge passes through bulb

Given,

I = 0.82A

t = 94s

Q = ?

Substituting the values in the above formula:

Q = I × t

Q = 0.82 × 94

Q = 77.08C

Hence, The charge passed through the light bulb during 94 s is 77.08C

Describe how coal-fired power plant converts chemical energy in coal into electricity energy.
Ray Of Light [21]
Coal is burned and is used to boil water, which in turn produces steam. Now this steam is passed through nozzles. The steam turns a steam turbine. Now the turbine is coupled to a generator. Generator is an electro magnetic device used for conversion of mechanical energy into electrical energy. So in the generator a voltage difference is created and converted into electrical.
