Mass of grain of sand = 6*10⁻²

Mass of earth = 6*10²⁸

Now we have to find how many times is the mass of grain of sand small than the mass of earth.

In order to find that we have to divide the mass of earth by mass of grain of sand.

So, dividing 6*10²⁸ by 6*10⁻²,

When we divide in exponents , we have this division rule,

xᵃ/ xᵇ = x⁽ᵃ⁻ᵇ⁾

When we divide two expressions with same base, the powers get subtracted.

Applying this rule to our question,

we get 6*10⁽²⁸⁺²⁾

On simplifying, we get

6*10³⁰

Answer: The mass of grain of sand is 6*10³⁰ times smaller than the mass of earth.

What is the period of the graph of the equation y = a sin bx?
steposvetlana [31]

T=2π/|b|. The period of an equation of the form y = a sin bx is T=2π/|b|.

In mathematics the curve that graphically represents the sine function and also that function itself is called sinusoid or sinusoid. It is a curve that describes a repetitive and smooth oscillation. It can be represented as y(x) = a sin (ωx+φ) where a is the amplitude, ω is the angular velocity with ω=2πf, (ωx+φ) is the oscillation phase, and φ the initial phase.

The period T of the sin function is T=1/f, from the equation ω=2πf we can clear f and substitute in T=1/f.

f=ω/2π

Substituting in T=1/f:

T=1/ω/2π -------> T = 2π/ω

For the example y = a sin bx, we have that a is the amplitude, b is ω and the initial phase φ = 0. So, we have that the period T of the function a sin bx is:

T=2π/|b|
