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

While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile's acceleration? (Reme
djverab [1.8K]

Considering that while traveling on a road with a<u> final speed of 15 m/s</u>, and an<u> initial speed of 24 m/s</u>, with a given time <u>of 12 seconds.</u>

To calculate the acceleration, we apply the following formula:

α = Vf - Vo/t

We add our data into the formula and solve:

α = 15 m/s - 24 m/s/12 sec

α = -0.75 m/s²

Therefore, the acceleration of the car is -0.75 m/s².
