Which of the following is a true statement about magnetic fields

Physics
1 answer:
zaharov [31]3 years ago
8 0

a. the larger the current, the larger the magnetic field

Explanation:

The magnetic field produced by a current-carrying wire is given by the equation:

B=\frac{\mu_0 I}{2\pi r}

where

\mu_0 is the vacuum permeability

I is the current in the wire

r is the distance from the wire at which the field strength is calculated

From the equation, we notice the following points:

  • The strength of the magnetic field is directly proportional to the current in the wire
  • The strength of the magnetic field is inversely proportional to the distance from the wire

Therefore, the only correct option in the list is

a. the larger the current, the larger the magnetic field

discuss the difference between molarity and molality, state the units of each, state the symbol of each, and give an example of
Afina-wow [57]
Molarity and molality both describe the concentration of a substance in terms of moles.
Molarity describes the number of moles of a substance per unit of volume, typically per liter (mol/l).
Molality describes the number of moles per unit of mass, typically kilograms (mol/kg). 
When determining the molality of a solution, mol/kg can be obtained by finding the number of moles in the substance, and dividing that number by the the total weight in kilograms of that substance.
When determining the molarity of a solution, mol/l can be obtained by dividing the number of moles in a substance by the total volume in liters of that substance.

A block of amber is placed in water and a laser beam travels from the water through the amber. The angle of incidence is 35 degr
7nadin3 [17]
Answer: 1.88

Explanation

Applying Snell’s Law, sin(1)/sin(2) = n(2)/n(1), where n is the index of refraction and sin 1 and 2 being of incidence and refracted respectively.

1) sin35/sin24 = n(2)/1.33
2) 1.41 = n(2)/1.33
3) n(2) = 1.41 x 1.33
4) n(2) = 1.88

Hope this helps :)

3. Consider a locomotive and the rest of a freight train to be a single object. Suppose the locomotive is pulling the train up a
Nonamiya [84]

Answer:

Action - Pulling up the train.

Reaction - Friction on the locomotive

Explanation:

Locomotive is pulling the train upwards ,

Which is the action force applied by the locomotive,

As a reaction locomotive will be pulled by the train which is the reaction of pulling

Now, considering it as a action on locomotive , friction force will act on it as a reaction upwards which will result to move it upwards.

For train action is pulling up by locomotive and reaction will be friction acting on it downwards.
