Answer:

3a - 21

Step-by-step explanation:

Given

3(a - 7)

Required

Simplify

To do this, we apply distributive property;

3(a - 7)= 3 * a - 3 * 7

3(a - 7)= 3a - 21

Hence, the simplified form is 3a - 21

Divide 240g in the ratio 5:3:4​
Nastasia [14]

Answer:

240g in the ratio of 5:3:4

So we need to divide it evenly.

First add up all the ratios.
5+3+4= 12

Now divide 240 by the sum.

240/ 12 = 20

Now you multiply that into each ratio.

5*20 = 100

3*20 = 60

4*20 = 80
Now put it back in the ratio with the new numbers int he exact order as before.

Final Answer: 100 : 60 : 80

Check:

You can check by adding them all up to see if they all go into 240 OR you can divide them each by the number originaly given and you should get 20.

100 + 60 + 80 = 240

100 / 5 = 20

60/3 = 20

80/4 = 20

find the flux of the constant vector field v→=3i→ 2j→−5k→ through a square plate of area 25 in the xz-plane oriented in the posi
Readme [11.4K]

The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.

<h3>What is Electric Flux?</h3>
  • A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
  • According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
  • A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
  • Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
  • The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
  • A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.
