if you could generate energy by fusing the hydrogen in solution a, how much of the solution would you need to generate the electrical energy used daily in a certain home? energy released by fusion of hydrogen in 1 liter of solution A = 7.6*10^10 Electrical energy used daily in a certain family home = 3*10^4

Answers

Answer 1

Answer:

We know that:

Energy released by fusion of hydrogen in 1 liter of solution A = 7.6x10^10 J

Energy used daily in a certain family home = 3x10^4 J

(you did not write the units, so i suppose that are the same in both cases)

Then, if x is the number of liters of solution A used, the energy produced will be:

E(x) = x*7.6x10^10 J

And we want this equal to 3x10^4

then:

E(x) = x*7.6x10^10 J = 3x10^4 j

now we solve this for x.

x = (3x10^4 j)/(7.6x10^10 j) = 3.9x10^-7

Then you need to use 3.9x10^-7 L of solution a.

What is (6x10^6)(4x10^-1) ?

Answers

Answer:

Step-by-step explanation:

Multiply the 6 and 4 together. 6*4 = 24

The next part is a bit tricky. Add the powers on the base 10. Keep the base 10.

10^(6 - 1) = 10^5

Now put the two parts together. 24 * 10^5

The number in front of the 10 must be between 1 and 10.

So 24 can be written as 24 = 2.4 * 10^1

2.4 * 10^1 * 10^5 = 2.4 * 10^(5 + 1) = 2.4 * 10^6

Answers

Answer:

acceleration refers to the rate of change in velocity

Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).

Answers

Answer:

The answer is

[tex]y = - \frac{2}{3} x + \frac{22}{3} [/tex]

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

Since the lines are parallel their slope are also the same

So the slope of parallel line = - 2/3

So the equation of the line containing the point (8 , 2) and slope - 2/3 is

[tex]y - 2 = - \frac{2}{3} (x - 8) \\ y - 2 = - \frac{ 2}{3} x + \frac{16}{3} \\ y = - \frac{2}{3} x + \frac{16}{3} + 2[/tex]

We have the final answer as

[tex]y = - \frac{2}{3} x + \frac{22}{3} [/tex]

Hope this helps you

Slope intercept form: y = mx + b

Parallel lines have the same slope, so the slope is -2/3.

We can solve using point slope form.

y - 2 = -2/3(x - 8)

y - 2 = -2/3x + 16/3

y = -2/3x + 22/3

With the substitution u = sin(x), we get integral 16 sin^2 (x) cos(x) dx = 16 integral u^2 du. which integrates to + C. Substituting back in to get the answer in terms of sin(x), we have integral 16 sin^2 (x) cos (x) dx = + C.

So

   [tex]Let \  u  =  sin(x)[/tex]

=>  [tex]\frac{du}{dx}  =  cos (x)[/tex]

=>   [tex]du  =  cos(x)dx[/tex]
