The velocity of a 10.0 kg object that has 720 J of kinetic energy is m/s. (Report the answer to two significant figures.)

12 m/s

Explanation:

Data provided in the question

Object = 10.0 kg

Kinetic energy = 720 J

Based on the above information, the velocity is

As we know that

Kinetic energy refers to motion energy. If an object has motion it can be vertical or horizontal that contains kinetic energy

720 = 10.0v^2 /2

So, after solving this

The velocity is 12 m/s

B. Geosphere

A. Biosphere

A. Atmosphere

Explanation:

Volcanic eruptions occurs within the Geosphere. The geosphere is the rock solid earth make up of rocks that extends into the deep interior.

Magma formed deep within the crust rises to elevated parts and finally erupts as lava on the surface. When they cool, they solidify to form volcanic rocks.

The volcanic eruptions affects the biosphere significantly. The biosphere is the portion of the earth where all life forms exists.

Gases and ash spewed during an eruption into the atmosphere causes severe changes to weather and leads to pollution. The atmosphere is the gaseous envelope round the earth.
