The bus will have the highest kinetic energy and the bike will have the least kinetic energy because kinetic energy =1/2 mass × velocity squared

In order to answer that, we would have to take the mass of each of them. The higher the mass, means there is higher the kinetic energy. We use the equation:

Ek = 1/2*m*v^2

Since velocity will be the same speed, it will be constant. The mass is what makes the difference with the bus having the maximum and the bike having the minimum kinetic energy.

anastassius [24]
36 × \frac{2}{9}

Since 9 is a factor of 36 you can reduce the 36 to 4 and the 9 to one 

Then just multiply what is left

4 <span>× 2 = 8

So, Mark completed 8 passes.</span>

The diameter of cold virus cell is about 3x10-9 meter,and the diameter of a streptoccus bacterium cell is about 9x10-7 meter. Wh
Archy [21]

Here we need to compare the orders of magnitude of two measures.

We will see that the bacteria is<em> 300 times larger than the virus.</em>

We know that:

The diameter of the virus-cell is:

D_v = 3 \cdot 10^{-9} m

The diameter of the bacteria cell is:

D_b = 9 \cdot 10^{-7} m

So, to compare them, first notice that both are in the same units, meters, so we only need to <u>compare the numbers</u>.

Is common sense to identify the one with the largest exponent as the largest number, and the largest exponent is -7, thus <u>the bacteria should be the larger one.</u>

But let's prove this with math, remember the property:

\frac{a^n}{a^m} = a^{n - m}

Let's take the quotient between the diameters and see what we get, I will use the <u>diameter of the bacteria in the numerator</u>, thus <u>if the quotient is larger than 1, it would mean that the bacteria is greater and by how much.</u>

quotient = \frac{ 9 \cdot 10^{-7} m}{ 3 \cdot 10^{-9} m}  = \frac{9}{3} \cdot 10^{-7 + 9}\\\\= 3*10^2

So we can say that the bacteria is 3*10^2 = 3*100 = 300 times larger than the virus.
