Answer:

Option 2 is correct.

Step-by-step explanation:

We have been given diameter of the tank 9 ft and height of the cylindrical water tank 12 ft

Radius is half of diameter that is 9/2=4.5

Since, water surface is 2 ft from the top

New height will become 12-2=10 ft

We have to find how much water tank contains means the capacity of tank to contain water

We will find volume of the cylindrical water tank by using formula:

volume=\pi\cdot r^2\cdot h

On substituting the values r=4.5,h=10 and\pi=3.14we get

volume=3.14\cdot (4.5)^2\cdot 10

\Rightarrow volume=3.14\20.25\cdot 10

\Rightarrow volume=635.85=636 ft^3

Therefore,Option 2 is correct.

what is the kinetic energy of a 1 kilogram ball is thrown into the air with an initial velocity of 3 m/sec
s344n2d4d5 [400]
Data:
m (mass) = 1 Kg
s (speed) = 3 m/s
Kinetic energy = ? (Joule)


Formula (Kinetic energy)
E_{k} =  \frac{m*s^2}{2}

Solving:
E_{k} = \frac{m*s^2}{2}
E_{k} =  \frac{1*3^2}{2}
E_{k} =  \frac{1*9}{2}
E_{k} =  \frac{9}{2}
\boxed{\boxed{E_{k} = 4.5\:J}}\end{array}}\qquad\quad\checkmark

Answer:

5.A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

6.The Nazca plate is an oceanic plate, while the South American plate is continental. The fast moving Nazca plate is moving east towards the South American plate at a downward angle and converging. This process is called subduction, resulting in frequent earthquakes & production of the Andes Mountains.

7.The Nazca plate forms the southeastern part of the Pacific plate. The Nazca and the Pacific plate share both divergent and transform type of plate boundary. The Pacific and the Nazca plate are separating at an increasing rate of about 122-142mm/year.

8.Convection currents in the mantle and in the ocean are similar because they both are responsible for the shaping the Earth's surface. Two forces are behind the movement of Earth's huge land masses. Due to combined action of convection currents and gravity, Earth's plates are in constant motion.

What was done to test if Comets are responsible for 1/2 the Earth's water?
My name is Ann [436]

✯Hello✯

↪  A satellite was crashed into a comet (on purpose of course)

↪  When it crashed a huge amount of water gushed out

↪  It was over hundreds of thousands of litres

↪  These proved that most of the water came from Comets for the world's first oceans
