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

A 0.500-kg stone is moving in a vertical circular path attached to a string that is 75.0 cm long. The stone is moving around the
Semenov [28]

Answer:

B. 7.07 m/s

Explanation:

The velocity of the stone when it leaves the circular path is its tangential velocity, v, which is given by

v=\omega r

where \omega is the angular speed and r is the radius of the circular path.

\omega is given by

\omega = 2\pi f

where f is the frequency of revolution.

Thus

v=2\pi fr

Using values from the question,

v=2\pi\times 1.50\times0.75

<em>Note the conversion of 75 cm to 0.75 m</em>

v=2\times3.14\times 1.50\times0.75 = 9.42\times0.75 = 7.065=7.07

A plane is landing. It started at 400m/s and ended up at 50m/s after 30 seconds. What is it's acceleration?
quester [9]

Give u = start velocity

        v = end velocity

v = u + at

50 = 400 + a*30

30a = -350

a = -116.67 m/s^{2}

**Why the accecleration is negative number**

Because displacement, velocity, and acceleration are VECTOR QUANTITIES.

Vector Quantity must have direction.

A shopping mall has a length of 200 m and a width of 75 m. What is the area of the mall?
sweet [91]
To find the area, we just need to multiply the length by the width. 200 x 75 = 15,000. The mall has an area of 15,000 sq. feet.
