prohojiy [21]

Answer:

Nuclear fission

Explanation:

Nuclear science is the field of physics that explains the atomic theory. It also explains the behavior, structure, and component parts of atomic nuclei.

Nuclear fission is used in nuclear power plants.

It is a great deal of radioactive waste that releases a great deal of energy with a little radioactivity.

In this process, the nucleus of an atom splits into two or more smaller and lighter nuclei.

I can’t figure this problem out
Natalka [10]

Answer:

Explanation:

Alright so the way to do this is to use properties of integrals to make our life easier.

So we have:

\int\limits^4_1 {(3f(x)+2)} \, dx

So lets break this up into two different integrals that represent the same area.

\int\limits^4_0 {f(x)} \, dx - \int\limits^1_0 {f(x)} \, dx = \int\limits^4_1 {f(x)} \, dx

Lets think about what is going on up there. The integral from four to zero gives us the area under the curve of f(x) from four to zero. If we subtract this from the integral from one to zero (the area under f from one to zero) we are left with the area under f from four to one! Hence:

\int\limits^4_1 {f(x)} \, dx

But since we have these values we can say that:

-3 - 2 = -5

Which means that \int\limits^4_1 {f(x)} \, dx = -5

So now we can evaluate \int\limits^4_1 {(3f(x)+2)} \, dx

Lets first break up our integrand into two integrals

\int\limits^4_1 {(3f(x)+2)} \, dx = 3\int\limits^4_1{f(x)} \, dx + 2\int\limits^4_1 {} \, dx

Now we can evaluate this:

We know that \int\limits^4_1 {f(x)} \, dx = -5

So:

3(-5)+2[x] where x is evaluated at 4 to 1 so

-15 + 2(3)

So we are left with -15 + 6 = -9

PLEASE HELP!! THIS IS DUE IN 10 MINS!!!
Svetradugi [14.3K]

Answer:

A farmer would chose a luxury crop over a high caloric or nutritionally valued crop because a luxury crop would generate them more profit.

These are non-subsistence crops, ones that are not necessary to survive and be healthy, but luxury goods like the name implies. People are willing to pay more for them for this reason.
