See the answer to the same question posted previously.

Just divide by the permeability of free space  μ0 = 1.2566370614×10⁻⁶Wb/A-m

$${\frac{\left({\mathtt{750}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{6}}}\right)}{\left({\mathtt{1.256\: \!637\: \!06}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{6}}}\right)}} = {\mathtt{596.831\: \!037\: \!276\: \!586\: \!447\: \!3}}$$

Relative permeability ≈ 597

The area of a triangle is given by half the base times the height.  There are an infinite number of triangles of different bases and heights that will have an area of magnitude 854.

Kinetic energy is (1/2)*mass*velocity²

$${\mathtt{ke}} = \left({\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right){\mathtt{\,\times\,}}{\mathtt{0.5}}{\mathtt{\,\times\,}}{{\mathtt{1.4}}}^{{\mathtt{2}}} \Rightarrow {\mathtt{ke}} = {\mathtt{0.49}}$$

The kinetic energy is 0.49 joules

See the answer in your previous (anonymous) post.

Force (weight) is mass*acceleration, so the mass of the object is m = 5.10/9.81 kg.

Mass is the same at all heights, so when force (weight) is 3.81N the gravitational acceleration is a = 3.81/(5.10/9.81) m/s². 

$${\mathtt{a}} = {\frac{{\mathtt{3.81}}{\mathtt{\,\times\,}}{\mathtt{9.81}}}{{\mathtt{5.1}}}} \Rightarrow {\mathtt{a}} = {\mathtt{7.328\: \!647\: \!058\: \!823\: \!529\: \!4}}$$

a ≈ 7.33 m/s²

To four decimal places sin 23° is 0.3907

10 x 10 x10 = 1000 cubic feet

$${\frac{{\mathtt{x}}}{{\mathtt{4}}}}$$ = $${\frac{{\mathtt{7}}}{{\mathtt{2}}}}$$

This is a proportion, so you can cross-multiply:

2 * x = 4 * 7

2x = 28

Divide by 2:

x = 14

Sorry about that.. I was the one asking for help. I found the answer, Thanks for the reply though...Cheers

This question is ambiguous. You are not likely to receive a reply.

Resubmit with either an image of the circuit, or unambiguous wording.

As it stands the resistors will not divide the voltage unless there is current flow -this question states unloaded.The measurement will be ZERO (where is CPhill?).

For Part 2, does "connected across the output" mean before or after the resistors?

Puzzle 1 answer: I am confused. Don't get it.

Your welcome

I thought it was always backwards instead?you do lengthXwidth to find the area?Like 427*2=854 427 being something like length and two being width.Maybe chris can explain to us both?

Thanks zegroes.

The answer is 50.

Yes! I needed payback for the time rosala got one right that i didnt!

Remember that we perform any multiplications/divisions first as we encounter them from left to right......

So, the first rhing we encounter is a division.......7/7 = 1

So we have

7 + 1 + 7*7 - 7

Next, we encounter a multiplication......7*7  = 49

So we have

7 + 1 + 49 - 7     

Now, we just add and subtract....this gives

8 + 49 - 7   =

57 - 7 =

50

The answer is 10.

So we square the three first ok i get it know thanks Chris

We have this zegroes:

√(x - 1) = 3

Let's square both sides........this gives........

x - 1 = 9

Add 1 to both sides

x = 10

And that's it.......
