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

Alexxx [7]

Answer: vf1/vf2= 1/ sqrt(2)

Explanation :on the moon no drag force so we have only the  force of gravity. aceleration is g(moon)= 1.62m/s2.the rest is basic kinematics

if the rock travels H to the bottom we can calculate velocity:

vo=0m/s (drops the rock)  , yo=0

vf*vf= vo*vo+2g(y-yo)

when the rock is halfway  y = H/2 so:

vf1*vf1=2*g*H/2 so vf1 = sqrt(gH)

when the rock reach the bottom y=H so:

vf2*vf2=2*g*H so vf2 = sqrt(2gH)

so vf1/vf2= 1/ sqrt(2)

good luck from colombia

Sound waves travel at the rate of 343 m/s at 20°C. If a man standing 450 meters away from the wall of a canyon yells, “Hello,” h
nekit [7.7K]

Answer:

2.62seconds

Explanation:

Speed is defined as the ratio of the distance covered by a body with respect to time.

Speed v = Distance (s)/Time (t)

For a traveling sound wave, the distance between the source of a sound and the reflector is '2S'.

Speed v = 2 × distance (S)/Time (T)

V = 2S/t

2S = vt

Given speed of the wave = 342m/s

Distance covered = 450m

t = 2S/v

t = (2×450)/343

t = 900/343

t = 2.62seconds

It will take him 2.62seconds for him to hear his own voice echo off of the wall.
