Kinetic energy = 1/2 * mass * velocity^2 so Ke = 1/2*(155*10^3 g)*18^2 which is 25,110,000 joules.

In an experiment, a certain colony of bacteria initially has a population of 50,000. A reading is taken every 2 hours, and at th
Iteru [2.4K]

Answer:

1) Recursive definition: p_n = (50,000)3^n

2) At the beginning of the 4th interval

Explanation:

1)

The initial population of the bacteria at time zero is

p_0 = 50,000

Here we are told that the reading is taken every two hours; we call this time interval "n", so

n=2 h

And also, after every time interval n, the number of bacteria has tripled.

This means that when n = 1,

p_1 = 3 p_0

And when n=2,

p_2 = 3 p_1 = 3(3p_0)=9 p_0

Applied recursively, we get

p_n = 3^n p_0

And substituting p0,

p_n = (50,000)3^n (1)

2)

Here we want to find at the beginning of which interval there are

p=1,350,000

bacteria.

This means that we can rewrite eq.(1) as

1,350,000=(50,000)3^n

By simplifying,

27=3^n

Which means that

n=3

However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.

If a paper clip floats on water, what would happen to it if you if you drop soap near it?
Mars2501 [29]

Nothing really big... It floats because of density not surface tension.

But You can try and discover what will happen.  :)

(   P.S if you'll drop soapstone it will probably create nice waves...  )
