Answer:

A cell is the basic block of life and is always changing to fit its environment.

Explanation:

A cell is the basic founding block of a living organisms. In other words, a cell is the basic membrane  unit which contains fundamental molecules of life. It is the cell that all living things are composed of.

The cell always changes with the surroundings and environment and it adapts to it. The cells requires a constant adjustments as the conditions inside and the outside the cells changes to keep a stable internal environment. Because the environment internally and externally is always changing, the cell continuously make adjustments to stay at or the near the set point.

A thin oil slick (no=1.50) floats on water (nw=1.33). When a beam of white light strikes this film at normal incidence from air,
Sedbober [7]

Answer:

The (minimum) thickness of the oil slick is 325 nm.

Explanation:

Let the (minimum) thickness of the oil slick = t_{o}

Therefore:

2t_{o} = (m_{red}+\frac{1}{2})*λ_{red}/n_{o}       (1)

similarly,

2t_{o}=(m_{violet}+\frac{1}{2})*λ_{violet}/n_{o}                                (2)

Thus, equation 1 = equation 2

(m_{red}+\frac{1}{2})*λ_{red} /n_{o} = (m_{violet}+\frac{1}{2})*λ_{violet}/n_{o}

Where:

λ_{red} = 650 nm

λ_{violet} = 390 nm

n_{o} = 1.5

Therefore:

\frac{2m_{violet}+1 }{2n_{red}+1 }=650/390=5/3

This shows that,

m_{violet}=2

m_{red}=1

Thus, using equation 2

t_{o}=\frac{5*390}{2*2*1.5} =325 nm

How much power does an Ox pulling a plow 20 m cross a field, exerting 120J of work over a period of 15 s?​
Aleksandr-060686 [28]

Answer:

8W

Explanation:

Given parameters:

Distance covered  = 20m

Work done  = 120J

Time  = 15s

Unknown:

How much power does the Ox exerts  = ?

Solution:

Power is the rate at which work is being done

  Power  = \frac{Work done }{time}  

 Power exerted by ox  = \frac{120}{15}   = 8W
