The answer is ; Tectonic plates

The plates sit above the ‘plastic’ mantle and move due to the convection currents in the underlying mantle. There are approximately 7 major tectonic plates of the lithosphere. Where some of these plates collide is called a convergence/ destructive boundary while where they move away from each other is called a divergent/constructive boundary.

Write 0.00000009345 in Engineering Notation with 3 significant figures
melisa1 [442]

Answer:

93.43\times 10^{-9}

Explanation:

Scientific notation is the way of writing numbers which are either large or small. The number is written in the scientific notation when the number is between 1 and 10 and then multiplied by the power of 10. Engineering notation is the same version of the scientific notation but the number can be between 1 and 1000 and in this exponent of the ten is divisible by three.

For example, 1000^2 is to be written as 10^6 in engineering notation.

The given number:

0.00000009345 can be written as 93.425\times 10^{-9}

Answer upto 4 significant digits = 93.43\times 10^{-9}
