What do you do if you are measuring something and it is between two whole numbers?

Physics

Umm, I guess it really depends on what these numbers are for but what I can say is if you put this under physics then decimals are used very often and help express parts of numbers for this particular problem.And if it's directly between the two then it's 0.50 added to that smaller number,I hope that helps

A circular coil has a 18.0 cm radius and consists of 25.0 closely wound turns of wire. An externally produced magnetic field of
djverab [1.8K]

Answer:

The magnetic flux links to its turns = 7.6 \times10^{-3} Wb.

Explanation:

Given :

Radius of circular coil = 18 \times 10^{-2} m

Number of turns = 25

Magnetic field = 3 \times10^{-3} T

Magnetic flux (Φ) is a measure of the magnetic field lines passes through a given area. The unit of magnetic flux is weber (Wb).

We know that,

⇒    Φ = BA

Where B = ext. magnetic field, A = area of loop or coil.

But here given in question, we have turns of wire so our above eq. modified as follows.

⇒   Φ = NBA

Where N = no. of turns.

∴    Φ = 25 \times 3 \times 10^{-3}  \pi (18 \times10^{-2} )^{2}

     Φ = 7.6 \times 10^{-3} Wb

Thus, the magnetic flux links to its turns = 7.6 \times 10^{-3} Wb

Find the magnitude & direction: 50N 25 N 35 N 10N
adoni [48]

F1x + F2x = Rx

↓

Rx = F1x + F2x

↓

Rx = F1 cos45° + F2

↓

Rx = (50N)(cos45°) + 60N

↓

Rx = 95N

Similarly, if we sum all the y components, we will get the y component of the resultant force:

F1y + F2y = Ry

↓

Ry = F1y + F2y

↓

Ry = F1 sin45° + 0

↓

Ry = F1 sin45°

↓

Ry = (50N)(sin45°)

↓

Ry = 35N

At this point, we know the x and y components of R, which we can use to find the magnitude and direction of R:

Rx = 95N

Ry = 35N
