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 fully loaded, slow-moving freight elevator has a cab with a total mass of 1250 kg, which is required to travel upward 49 m in
insens350 [35]

Answer:

659.01W

Explanation:

The cab has a mass of 1250 kg, the weight of the cab represented by Wc will be

Wc = mass of the cab × acceleration due to gravity in m/s²

Wc = 1250 × 9.81 = 12262.5 N

but the counter weight of the elevator represented by We = mass × acceleration due to gravity = 995 × 9.81 = 9760.95 N

Net weight = weight of the cab - counter weight of the elevator = Wc - We = 12262.5 - 9760.95 = 2501.55 N

the motor of the elevator will have to provide this in form of work

work done by the elevator to lift the cab to height of 49 m = net weight × distance (height) = 2501.55 × 49m

power provided by the motor of the elevator = workdone by the motor / time in seconds

Power = (2501.55 × 49) ÷ ( 3.1 × 60 seconds) = 659.01 W
