IN a physics lab, a student discovers that the magnitude of the magnetic field at a certain distance from a long wire is 4.0μT. If the wire carries a current of 5.0 A, what is the distance of the magnetic field from the wire?

Answers

Answer:

0.25 m

Explanation:

The intensity of the magnetic field around a current-carrying wire is given by:

$B=(\mu_0 I)/(2 \pi r)$

where

$\mu_0 = 4\pi \cdot 10^(-7)Tm/A$ is the permeabilty of free space

I is the current

r is the distance from the wire

In this problem, we know:

$B=4 \mu T=4 \cdot 10^(-6) T$ is the magnetic field

$I=5.0 A$ is the current in the wire

Re-arranging the equation, we can find the distance of the field from the wire:

$r=(\mu_0 I)/(2 \pi B)=((4\pi \cdot 10^(-7))(5.0 A))/(2\pi(4\cdot 10^(-6) T))=0.25 m$

A softball player leaves the batters box, overruns first base by 3.0 meters, and then returns to first base. Compared to the total distance traveled by the player, how much smaller or larger is the magnitude of the players total displacement from the batters box?

Answers

The distance traveled during his run is 6 meters more than his displacement. Displacement only depends on the end points. The route taken is irrelevant to displacement.

Four parallel-plate capacitors are constructed using square plates, and each has a dielectric inserted between the plates.?Rank the capacitance of each capacitor in order from highest to lowest.

A = side length (L/2) ; distance between plates (d) ; dielectric current (k)

B = side length (L) ; distance between plates (d/2) ; dielectric current (4k)

C = side length (2L) ; distance between plates (d) ; dielectric current (2k)

D = side length (L) ; distance between plates (2d) ; dielectric current (2k)

Answers

Final answer:

The capacitance of the four capacitors, ranked from highest to lowest, is B = C (they both have equal capacitance), followed by D, and then A.

Explanation:

The capacitance of a parallel-plate capacitor is given by C = εA/d, where ε is the permittivity of the dielectric material (which is equal to the product of the vacuum permittivity and the relative permittivity or dielectric constant k), A is the area of one of the plates, and d is the separation between the plates.

Applying this formula to the four capacitors and simplifying:

Capacitor A: Cap = k(0.5L)^2/d = 0.25kL^2/d
Capacitor B: Cap = 4k(L)^2/(0.5d) = 8kL^2/d
Capacitor C: Cap = 2k(2L)^2/d = 8kL^2/d
Capacitor D: Cap = 2k(L)^2/(2d) = kL^2/d

When ranked from highest to lowest capacitance, the order will be B = C > D > A.

Why are x-rays and the radiation emitted by radioisotopes called ionizing radiation?

Answers

Ionizing radiation is any type of particle or electromagnetic wave that carries enough energy to ionize or remove electrons from an atom. There are two types of electromagnetic waves that can ionize atoms: X-rays and gamma-rays, and sometimes they have the same energy. CREDIT: PhysicsCentral.com
