0.25 m is the radius of the coil. when a round flat metal coil has 180 turns and negligible resistance.
What does the term "resistance" mean?the action of defending oneself from an aggressor or refusing to accept something.
We must take the Faraday law into account in order to explain this issue.
When the magnetic field changes due to the induced emf, as indicated by the equation d/dt, the voltage equals I*R=17*6=102 V.
After a coil, the magnetic flux is as follows:
If N is equal to N*A*B, then d is equal to N*A*dB/dt, where A and N are the coil's area and number of turns.
A=*R2, where R is the coil's radius.
Finally, there is;
dФ/dt= N*π*R^2*dB/dt then
R= [dФ/dt/(N*π*dB/dt)]^1/2= [102/(180*π*3)]1/2=245.2*10^-3=≅0.25m

O ability to extract the influence of confounded variables.
O fact that it occurs in real-world settings.
Option D; A great strength of correlational research is the fact that it occurs in real-world settings.
When doing correlational research, which is a type of nonexperimental study, the researcher examines two variables and assesses their statistical relationship (i.e., the correlation) with little to no effort made to account for unrelated variables. Since it helps us to ascertain the magnitude and direction of correlations between two variables, correlational research is helpful. Contrarily, correlation is limited since it only provides evidence of a link and provides little information about its underlying mechanisms. Through the correlational method, relationships between variables are sought. For instance, a researcher would be interested to know if a user's privacy preferences in a social networking software are influenced by their personality, IQ, level of education, employment status, age, gender, income, and other factors

HTML Editor X BIVA -A- IX E EDO V E - Paragraph 12pt Predict what would happen if during an accident the periosteum and the muscle were removed from a side of a long bone that is broken. Describe the advantages and disadvantages of fusing vertebrae.
The removal of the periosteum causes shock, distress, tissue damage, and skin puncture. The fusing of vertebrae increases the stability, strength, and shape of the spine. But it will add stress and increase the rate of spine degradation.
The periosteum is the covering that surrounds the bones and supplies the bone with blood, nerves, and cells they require to develop and heal. The bone receives nutrients and sensations from this.
If the periosteum and the muscle are removed because of the accident, it will cause distress and severe shock. Because the nerve in this is helpful in the sensation of pain caused by tissue damage. So when this periosteum is removed, the lack of sensation will limit the regeneration of osteoblasts.
The muscle surrounding will also affect balance, and stability. Also, cause more damage or skin puncture.
Advantages:
Fusing vertebrae helps to eliminate and remove the segmentation in the vertebral column. It helps to restore, strengthen, and stabilize the shape of the spinal cord. It also corrects deformity and reduces pain.Disadvantages:
Extra stress will be placed on the vertebrae above and below the fused part. Additionally, it speeds up the degeneration of the spine. Regional segmental mobility is also altered.To know more about periosteum:

You are going to invent a new device that people can use instead of a microwave to warm up leftovers. Which type of electromagnetic wave would be most useful to investigate?.
If we are going to invent a new device that people can use instead of a microwave oven to warm up leftovers, the type of electromagnetic wave that would be most useful to investigate would probably be infrared waves.
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field.
Since electromagnetic waves are of different energy range and different electromagnetic waves are used for different works.
Higher energy range electromagnetic waves cannot be used to expose for human because they can cause damage to them. So, we can not use them for warming purpose as they are dangerous. So X rays and Gamma rays can not be used
And least energy waves can also not be used. So, radio waves which are least energy cannot be used for the purpose of warming.
So correct answer for the replacement of microwaves is infrared waves because they have sufficient energy that can be used to warm up.

Select one:
a.Einstein
b.Poisson
c.Fraunhofer
d.Fresnel
A diffraction pattern involving parallel rays is called (c) Fraunhofer diffraction.
Because of the far-field location of observation and the increasingly planar nature of the outgoing diffracted waves passing through the aperture, Fraunhofer diffraction is a type of wave diffraction that takes place when field waves are passed through an aperture or slit. This only results in a change in the size of the observed aperture image.
The parallel rays approximation can be used to view it at distances beyond the near-field distance of Fresnel diffraction, which modifies the size and form of the observed aperture image. This only happens when the Fresnel number at these distances.
Fraunhofer diffraction, which is typically explained through the use of observational experiments utilizing lenses to intentionally diffract light, is based on the notion that a wave is split into many outgoing waves when passing through an aperture, slit, or hole. When waves pass through, they are split into two diffracted waves that move at right angles to one another and the remaining incoming wave. These waves are frequently used in observational techniques by placing a screen in their path so that the image-pattern observed can be seen.

A) 1 m/s²
C) 0.2 m/s²
B) 2 m/s²
D) 0.5 m/s²
The acceleration due to gravity on asteroid X is approximately 0.5 m/s². The acceleration an object experiences as a result of gravitational force is known as acceleration due to gravity.
What is acceleration due to gravity ?To calculate the acceleration due to gravity on asteroid X, you need to first determine the mass of the astronaut. Since weight is a measure of the force of gravity on an object, and the force of gravity is directly proportional to the mass of the object, the mass of the astronaut can be calculated by dividing the weight on Earth by the acceleration due to gravity on Earth.The acceleration due to gravity on Earth = 9.8 meters per secondThe mass of the astronaut = 500 Newtons / 9.8 m/s^2, 50 Kg
The equation for gravitational force is F = Gm1m2/r^2,
where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them. Solving for r, you can calculate that the distance between the astronaut and the center of asteroid X is approximately 5 meters. Since the acceleration due to gravity is defined as the force of gravity divided by the mass of the object, you can use this distance to calculate the acceleration due to gravity on asteroid X. Dividing the force of gravity on the astronaut (25 Newtons) by the mass of the astronaut (51 kilograms).Calculate that the acceleration due to gravity on asteroid X = 0.49 meters per second squared.

Can someone explain how an avalanche occurs.
Answer:
Explanation:
Thousands of avalanches occur in Canada each year. They happen in all regions of Canada, but are more frequent in the mountains of British Columbia, Yukon and Alberta. Avalanches can be triggered by wind, rain, warming temperatures, snow and earthquakes. They can also be triggered by skiers, snowmobiles, hikers, vibrations from machinery or construction. Avalanche facts:
An avalanche occurs when a layer of snow collapses and slides downhill.
Avalanches are caused by four factors: a steep slope, snow cover, a weak layer in the snow cover and a trigger.
Roads and railway tracks may be rerouted to reduce risks.
Safe avalanches may be triggered in dangerous snow packs.
Avalanches can travel up to 90 km/h.
After one hour, only one in three victims buried in an avalanche is found alive. The most common causes of death are suffocation, wounds and hypothermia.
