What does Lenz's law mean?

Answers

Answer 1

Answer: named after the physicist Heinrich Lenz who formulated it in 1834, says: The direction of current induced in a conductor by a changing magnetic field due to Faraday's law of induction will be such that it will create a field that opposes the change that produced it.

Very popular in electromagnetism physics

Answer 2

Answer: The induced current in a loop is in the direction that creates a magnetic field thatopposes the change in magnetic flux through the area enclosed by the loop(That is, the induced current tends to keep the original magnetic flux through the circuit from changing). This is what Lenz's law states.

Answers

Answer: 38.25 m

Explanation:

In this situation we need to find the distance $d$ between the rabbit and the carrot, and we can use the following equation, since the rabbit's acceleration is constant:

$V^(2)=V_(o)^(2) + 2ad$ (1)

Where:

$V=13 m/s$ is the rabbit's maximum velocity (final velocity)

$V_(o)=4 m/s$ is the rabbit's initial velocity

$a=2 m/s^(2)$ is the rabbit's acceleration

$d$ is the distance between the rabbit and the carrot

Isolating $d$ :

$d=(V^(2)-V_(o)^(2))/(2a)$ (2)

$d=((13 m/s)^(2)-(4 m/s)^(2))/(2(2 m/s^(2)))$ (3)

Finally:

$d=38.25 m$

A toy cannon uses a spring to project a 5.24-g soft rubber ball. The spring is originally compressed by 5.01 cm and has a force constant of 8.08 N/m. When the cannon is fired, the ball moves 15.8 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 0 N on the ball.With what speed does the projectile leave the barrel of the cannon?

Answers

Answer:

Speed will be equal to 1.40 m/sec

Explanation:

Mass of the rubber ball m = 5.24 kg = 0.00524 kg

Spring is compressed by 5.01 cm

So x = 5.01 cm = 0.0501 m

Spring constant k = 8.08 N/m

Frictional force f = 0.031 N

Distance moved by ball d = 15.8 cm = 0.158 m

Energy gained by spring

$KE=(1)/(2)kx^2=(1)/(2)* 8.08* 0.0501^2=0.0101J$

Energy lost due to friction

$W=Fd=0.031* 0.158=0.0048J$

So remained energy to move the ball = 0.0101 - 0.0048 = 0.0052 J

This energy will be kinetic energy

$(1)/(2)mv^2=0.0052$

$(1)/(2)* 0.00524* v^2=0.0052$

v = 1.40 m/sec

What climate factor is responsible for the snow on my Kilimanjaro

Answers

The climate factor that is responsible for the amount of snow on Mt. Kilimanjaro is high elevation. In the concept of precipitation, as an air mass rises and cools, its capacity to hold water vapor lessens. This vapor condenses into water droplets, forming clouds. Terrain with high elevation attracts such formations, bringing with them cloudiness, rainfall, and snowfall.
