In a solution,a Is the substance being dissolved
Elena-2011 [213]
In a solution, a SOLUTE is the substance being dissolved.

In a solution, a SOLVENT is the substance in which something is dissolved.

For example in salt water, the salt is the solute. And the water is the solvent. Usually, which substance has a larger amount in the solution can be called a solvent. It doesn't matter if it's a gas, solid, or liquid. They can all be solute or solvents.

How to find weight in science
Kaylis [27]

There are several different methods, depending on the particular situation.  A few that might occasionally be useful include:

-- Read the label on the package.

-- Measure the mass and multiply by the local acceleration of gravity.

-- Measure the mass AND the local acceleration of gravity, then multiply.

-- Place the object or sample on a bathroom scale.

-- Place the object on one end of a symmetrical see-saw.  Through trial and error, determine the weight required on the other end to balance the system.

A 15.0 m \long copper wire, 2.20 mm in diameter including insulation, is tightly wrapped in a single layer with adjacent coils t
Hoochie [10]

a) 0.5 m

b) 4.77\cdot 10^{-3} T

Explanation:

a)

At the beginning, the length of the copper wire is:

L = 15.0 m

and the diameter (so, the thickness of each adjacent circle) is

t=2.20 mm = 0.0022 m

While the diameter of one circle of the solenoid is

d=2.10 cm = 0.021 m

So the perimeter of one circle is

p=\pi d=\pi (0.021)=0.0659 m

So the number of complete circles in the solenoid is

n=\frac{L}{p}=\frac{15.0}{0.0659}=227.6

The tickness of one circle is t, so the total length of the solenoid will be:

L'=nt=(227.6)(0.0022)=0.5 m

b)

The magnetic field at the center of a solenoid is given by

B=\mu_0 n I

where

\mu_0 is the vacuum permeability

n is the number of turns of the solenoid

I is the current in the solenoid

Here we have:

\mu_0 =4\pi \cdot 10^{-7}H/m is the vacuum permeability

n=227.6 is the number of turns in the solenoid (calculated in part a)

I = 16.7 A is the current in the solenoid

Substituting, we find:

B=(4\pi \cdot 10^{-7})(227.6)(16.7)=4.77\cdot 10^{-3} T
