How many times smaller is 2 × 10^-10 than 4 × 10^-5

natta225 [31]

Answer:

200,000

Step-by-step explanation:

To find how many times smaller is smaller number than greater number, divide greater number by smaller number.

Greater number $=4\times 10^{-5}$

Smaller number $=2\times 10^{-10}$

Then

$\dfrac{\text{Greater number}}{\text{Smaller number}}\\ \\=\dfrac{4\times 10^{-5}}{2\times 10^{-10}}\\ \\=\dfrac{4}{2}\times \dfrac{10^{-5}}{10^{-10}}\\ \\=2\times \dfrac{1}{10^{-5}}\\ \\=2\times 10^5\\ \\=2\times 100,000\\ \\=200,000$

If the force of 12n is applied to an object with a mass of 2k the object will accelerate what

astraxan [27]

I consider this physics

But, given that Newton's Second Law is F=ma and since you are given the mass and force, the acceleration can be easily calculated by isolating variable acceleration (a)

$F=ma$
$a = \frac{F}{m}$
$a= \frac{12 N}{2 kg}$
$a = 6 \frac{m}{s}$
