Which image shows an example of the electromagnetic force in action?

Answers

Answer 1

Answer:

The second image showing an electromagnet is an example of the electromagnetic force in action therefore the correct option is B

What is electromagnetic force?

It is a type of force that occur between electrically charged particles. The electromagnetic force is the combination of all the electrical and magnetic forces generated from any charged particle,

These electromagnetic forces either be attractive or repulsive.

The force generated from a simple bar magnet is an example of the electromagnative force, hence the correct option is B

Imagine you are in an open field where two loudspeakers are set up and connected to the same amplifier so that they emit sound waves in phase at 688 Hz. Take the speed of sound in air to be 344 m/s. Part A. If you are 3.00 m from speaker A directly to your right and 3.50 m from speaker B directly to your left, will the sound that you hear be louder than the sound you would hear if only one speaker were in use? a. yes b. no Because the path difference is equal to the wavelength of the sound, the sound originating at the two speakers will interfere constructively at your location and you will perceive a louder sound. Part B. What is the shortest distance d you need to walk forward to be at a point where you cannot hear the speakers? The forward direction is defined as being perpendicular to a line joining the two speakers and you start walking from the line that joins the two speakers.

How to find the period of a wave

Answers

The method to choose depends on what information you have, and
on what you can measure. Here are a few possible methods:

-- Measure the period. Start your clock when one peak
of the wave passes you. Stop the clock when the next
peak passes you. The time between the two peaks is
the wave's period.

-- Divide the wave's wavelength by its speed. That quotient
is the wave's period.

-- Use an electronic frequency meter to measure the wave's
frequency. Then take its reciprocal (divide ' 1 ' by it). The
result is the wave's period.

a ball is thrown upward at 25 m/s from the ground. what is the average velocity and average speed of the ball after 5 seconds?

Answers

When the ball reaches the highest point, its velocity will be zero. So final velocity is v=0m/s
Here, the time to reach highest point is equal to time to hit ground from highest point.
Consider upward motion, the acceleration of the ball is a=−g=−9.8m/s
2
(minus for motion opposite to gravity)
If t be the required time.
Using v=u+at,
0=25+(−9.8)t
⟹ t=2.5s
Thus the ball hits the ground after 2.5 seconds after reaching its highest point.

Answer:

Stimulants are a group of drugs that result in increased activity in the body. Sometimes referred to as “uppers,” these drugs are frequently abused due to their performance-enhancing and euphoric effects. Generally, those who abuse stimulants experience heightened energy levels and enhanced focus.

Stimulants speed up mental and physical processes, which can produce desirable effects in the short-term by increasing levels of dopamine in the brain. While users may feel great due to the short-term effects of stimulants, long-term abuse of these drugs can have significant consequences, which is why it is so important for those who abuse the drugs to get help as quickly as possible.

2. A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to five times her weight as she goes through the dip. Of r = 21.5 m, how fast is the roller coaster traveling at the bottom of the dip?

Answers

Answer: $v=√(4gr)$

Explanation:

Given

Passenger feels the seat of the car Pushing upward with a force equal to five times her weight

Therefore

$N-mg=(mv^2)/(r)$

it is given $N=5mg$

where N=normal reaction

$5mg-mg=(mv^2)/(r)$

thus $v=√(4gr)$
