The flash of lightning travels at the speed of light, which is about 186,000 miles per second. The sound of lightning (thunder)

4vir4ik [10]

Answer:

A. Distance of the lightning after 4 seconds = 744,000 miles

B. Distance of the lightning after n seconds = 186,000 * n

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of lightning = 186,000 miles per second

Speed of sound = 750 miles per hour

2. A. If you see a flash of lightning, then hear the thunder 4 seconds later, how far away is the lightning?

Distance of the lightning after 4 seconds = 186,000 * 4

Distance of the lightning after 4 seconds = 744,000 miles

B. Now let’s generalize that result. Suppose it takes n seconds to hear the thunder after a flash of lightning. How far away is the lightning, in terms of n?

Distance of the lightning after n seconds = 186,000 * n

Thomas Malthus, a political economist, showed that the human population would outstrip available resources unless kept in check

vredina [299]

Answer:

C. Darwin realized this also applied to plant and animal populations, and this struggle for existence resulted in an opportunity for natural selection to act on differences within populations.

Step-by-step explanation:

Thomas Malthus in his Malthusian theory of population concluded that since population increases geometrically and resources only increase arithmetically, there will reach a point in time when the resources will be not be able to sufficiently cater for the population.

The Charles Darwin theory of Evolution is based on five key observations and conclusions drawn from them. These observations and inferences are summarized as:

Species are more fertile. They birth more offspring than can grow to adulthood.
Populations remain fairly stable with miniscule fluctuations.
Food resources are limited, but are relatively constant most of the time.

Based off these observations, it is seen that there will be a struggle amongst the members of the specie for the limited resources.

In sexually reproducing species, generally no two individuals are identical. Variation is rampant.
Much of this variation is heritable.

From the last two observations, the species that survive then pass on their traits to their offspring and the cycle repeats itself with each subsequent generation being better evolved than the previous ones.

Thus, Darwin discovered that the Malthusian theory of population also applies to plant and animal populations where scarcity of resources gives room for natural selection to take place due to the variation within populations.

How would the fraction 5/1-sqrt 3. Be written if it’s denominator is rationalized using difference of squares?

Yanka [14]

Answer:

Step-by-step explanation:

5/(1-√3)=5*(1+√3)/(1-√3)(1+√3)= (5+5√3)/(1-3)= -(5+5√3)/2
