Answer:

Array: (a) All the messages a user has sent.

Variable: (b) The highest score a use has reached on the app. (c) A username and password to unlock the app.

Explanation:

An array generally has more than one value whereas a variable can only contain a single value at any particular point in time. In addition, a variable has a limit whereas an array does not have any maximum limit. Therefore, it can be concluded that option (a) will be stored as an array while options (b) and (c) will be stored as variables.

kobusy [5.1K]

Answer:

200 nm

Explanation:

We need a constructive interference to see the bright reflection

we know that 2t=m\lambda  where m=1 and \lambda is the wavelength of the gasoline

so \lambda =\frac{560}{1.4}=400nm

putting the value of m and \lambda in thickness equation

t=\frac{1\times 400}{2}=200nm

so the thickness of the film will be 200 nm

There is a population of owls in a forest. In one year there are 20 new owls born and 10 owls die. In this same year, 5 owls ent
Simora [160]

Answer:

The owls population increased by 13 in one year

Explanation:

The given data on the owl population are as follows;

The number of new owls born = 20 (positive increase in population)

The number of owls that die = 10 (negative decrease in population)

The number of owls that enter the forest = 5 (positive increase in population)

The number of owls that left the forest = 2 (negative decrease in population)

Let 'w' represent the number of new owls born, let 'x' represent the number of  owls that die, let 'y' represent the number of owls that enter the forest and let 'z' represent the number of owls that left the forest, we get;

The change in population, ΔP = w - x + y - z

By plugging in the values, we get;

ΔP = 20 - 10 + 5 - 2 = 13

The change in the population of owls in one year is an increase in 13 owls.
