If someone were to drop an orb from a height of 34,000 meters approximately, and then drop a second orb at 34,100 meters, estima

te how long it would take for the second orb to reach the ground if it takes the first orb 55~ seconds to impact.
Extra Info:
-The first orb weights 2 pounds and the second orb weights only 2.5 pounds.
-The ground is entirely flat and level. (as if you smashed a flattening board into the ground)
-They are both dropped with no force put into it, simply held up and let go of.
-Both Orbs are the same size, just different density.
-The heights are estimates and are not exact, hence the answer can be an estimated one.

(this question sparked from boredom ._.)
If info required I can provide.

Answer:

Explanation:

SO the ball falls 618 meters per second meaning that's how fast 2 pounds fall per second so i have to find out how fast .5 pounds falls which i think its 154 meters per second per .5 pounds meaning the second orb would fall 772 meters per second so the second orb would take 44.1 seconds to hit on impact. Im not sure if this is right but this is my best guess.

Drupady [299]

Answer:

h=f(t)= -17.5cos(\pi /3)+20.5

Explanation:

Amplitude is 35/2=17.5

Midline= Distance from ground + Amplitude = 17.5+3= 20.5

Period is time taken to finish 6 minutes

2π/b=T

2π/b=6

b=π/3

h=f(t)= -17.5cos(\pi /3)+20.5

An object has traveled 20 meters in 40 seconds what is its average speed
Mice21 [21]

Hello,


To solve we need to know the formula for speed

The formula is D/T=S     (Distance of time=speed)

Now all we have to do is plug in the numbers.

20/40= 1/2 or 0.5

SO the speed is 0.5 m/s


Have a great day!

A worker is thinking about two ways to get a box up 1.2 m onto a loading dock. He can use a force of 250 N to lift it straight u
harina [27]

Answer:

<em>The second option has a lower power output. P=30 W</em>

Explanation:

<u>Mechanical Power </u>

It is a physical magnitude that measures the rate a work W is done over time t.

\displaystyle P=\frac{W}{t}

Since W=F.d

\displaystyle P=\frac{F.d}{t}

The first option means the worker will lift the box by a distance of 1.2 meters in 3 seconds by applying 250 N of force. That produces a power of

\displaystyle P=\frac{(250). (1.2)}{3}=100\ Watt

The second option requires the worker applies 75 N of force and travel a distance of 4 meters for 10 seconds, thus the power is

\displaystyle P=\frac{(75). (4)}{10}=30\ Watt

The second option has a lower power output

wlad13 [49]

Answer:

915 Hz

Explanation:

The observed frequency from a sound source is given as

f₀ = f [(v + v₀)/(v+vₛ)]

where

f₀ = observed frequency of the sound by the observer = ?

f = actual frequency of the sound wave = 983 Hz

v = actual velocity of the sound waves = 343 m/s

vₛ = velocity of the source of the sound waves = 55.9 m/s

v₀ = velocity of the observer = 28.4 m/s

f₀ = 983 [(343+28.4)/(343+55.9)]

f₀ = 915.2 Hz = 915 Hz
