Lorico [155]

Answer:

  a = 0.701 m / s²

Explanation:

As the game is spinning the acceleration is centripetal

           a = v² /r

The park system after a small period of acceleration goes at a constant speed, for which we can use the relations of the uniform motion

           v = d / t

the distance of a circle is

           d = 2π r

we substitute

          a = (2π r / t) ² / r

          a = 4 pi² r / t²

           

let's calculate

          a = 4 pi² 12 / 26²

          a = 0.701 m / s²

Who created earthquake proof buildings?
klemol [59]

Answer:

Japanese created earthquake proof buildings

Explanation:

Countries like Japan where earthquakes are regular. So these important factors are downgraded to nice -to-haves behind the need of Japan structural stability. The Pacific ring of Fire and all its seismic activities are contributed to Japans strict building codes for skyscrapers and Towers. Building codes means, earthquakes proof structures are intended to withstand the earthquake.The prime example of an earthquake-ready country is Japan with its dedication to structural stability.

5 great examples are

1. Mori Tower

2. Tokyo Skytree

3.  Ark Hills Sengokuyama

4.fa-bo

5. Television House

A rocket in deep space has an empty mass of 220 kg and exhausts the hot gases of burned fuel at 2500 m/s. What mass of fuel is n
Scilla [17]

Answer:

Explanation:

Let fuel is released at the rate of dm / dt where m is mass of the fuel

thrust created on rocket

= d ( mv ) / dt

= v dm / dt

this is equal to force created on the rocket

= 220 dv / dt

so applying newton's law

v dm / dt = 220 dv / dt

v dm = 220 dv

dv / v = dm / 220

integrating on both sides

∫ dv / v    = ∫ dm / 220

lnv =  ( m₂ - m₁ ) / 220

ln4000 - ln 2500 = ( m₂ - m₁ ) / 220

( m₂ - m₁ ) = 220 x ( ln4000 - ln 2500 )

( m₂ - m₁ ) = 220 x ( 8.29  - 7.82 )

= 103.4 kg .
