The rate constant is 0.058/days and the population after 18 days is 412.38.

<h3>What is rate constant?</h3>

The rate constant of the population is calculated as follows;

N = N₀(2)^(rt)

where;

  • r is the rate constant
  • t of double of the population

when the population doubles, t = 12 days

2N₀ = N₀(2)^(12r)

2 = (2)^(12r)

ln(2) = 12r

r = ln(2)/12

r = 0.058/days

<h3>Population size after 18 days</h3>

The population size after 18 days is calculated as follows;

N = 200(2)^(0.058 x 18)

N = 412.38

Thus, the rate constant is 0.058/days and the population after 18 days is 412.38.

lidiya [134]

The position vector can be transcribed as:

i <span>points in the x-direction and j points in the y-direction.</span>

The magnitude of the vector is its dot product with itself:

<span>|A|2 = A·A</span>

<span>102  = (6 i + y j)•(6 i+ y j)            Note that i•j = 0, and  i•i  = j•j = 1 </span>

Discuss how friction is reduced in oce skating
belka [17]

Answer:

below

Explanation:

Ice melts, meaning it has a watery layer upon its surface. This allows things to be moving like they are on a liquid but it has the solidity of a solid. The thin metal of the ice skates also decrease the surface area meaning it exerts more force but in turn, it allows you to move faster and further reduces friction.

Suppose that you hear a clap of thunder 16 s after seeing the associated lightning strike. How far are you from the lightning st
riadik2000 [5.3K]

Answer:

d=5.376km

Explanation:

Since <em>light is so fast</em> we can assume no time passes between the lightning strikes and we observe it. We want to know then how far away did the strike occur for the sound to take 16s to reach our ears. Since the definition of velocity tells us that v=d/t, we can write d=vt=(336m/s)(16s)=5376m=5.376km
