Gazala makes the device shown in the diagram and uses it to pick up four paper clips on the point of the nail.What change would enable Gazala to pick up eight paper clips?

A) reversing the battery
B) reversing the nail and using the nail’s head
C) wrapping the wire around the nail more times
D) unwrapping several loops of the wire from the nail

Answers

Answer 1

Answer:

Answer:

The correct answer is C.

Explanation:

To pick up four clips at the tip of the nail, wrap the wire around the nail more times than it already has. This is because the attraction force of the electromagnet is directly proportional to the square of the magnetic field that is generated by passing a current through the coiled wire. The magnetic field, in turn, is proportional to the number of turns that this wire has around the magnetic element, so it is necessary to increase the number of turns so that the strength of the electromagnet is greater.

Have a nice day!

Answer 2

Answer:

C) wrapping the wire around the nail more times would enable Gazala to pick up eight more clips

Use z scores to compare the given values. The tallest living man at one time had a height of 233 cm. The shortest living man at that time had a height of 91.4 cm. Heights of men at that time had a mean of 174.45 cm and a standard deviation of 6.36 cm. Which of these two men had the height that was more extreme?

Answers

Answer:

The man with the more extreme height is the man with 91.4 cm.

Explanation:

We have two values: 233 cm and 91.4 cm. The z score for every value is calculated as:

$z=(x-m)/(s)$

Where x is the given value, m is the mean and s is the standard deviation. So, the z score for every height is:

For 233 cm:

$z=(233-174.45)/(6.36)=9.2059$

For 91.4 cm:

$z=(91.4-174.45)/(6.36)=-13.0582$

Then, the more extreme value is 91.4 cm because the z score has the highest absolute value. This is:

For 233 cm

absolute z = 9.2059

For 91.4 cm

absolute z = 13.0582

Finally, The man with the more extreme height is the man with 91.4 cm.

If a 100-N net force acts on a 50-kg car, what will the accelaration of the car be?

Answers

2m/s^2 how to get it: since you already know the force and mass and the formula for force is force=(mass)(acceleration) you isolate the variable of acceleration which is a by dividing (m)(a) by (m) which equals f/m=a then you plug in your known numbers where they go so f=100N m=50kg 100N/50kg= 2 therefore the acceleration is 2m/s^2 hope this helped you!!!

Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals. Which term do scientist use to describe these orbits

Answers

Planets in our solar system do not revolve around the sun in perfect circles. They revolve in the elliptical orbits.

What is the solar system?

The solar system consists of the planet's satellites, as well as numerous comets, asteroids, and meteoroids, as well as the interplanetary medium.

Planets in our solar system do not revolve around the sun in perfect circles. They revolve in the elliptical orbits.

Hence, option D is correct.

To learn more about the solar system, refer to the link;

Answer:

It is most likely the word elliptical.

Explanation:

Usually the term elliptical refers to the oval-like shape of a substance or path of an object. The question states, "Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals." Because the planets orbit around the sun in an oval-like path, those orbits can be described as elliptical. Scientists also normally use this word to describe the same thing; Therefore, your answer is elliptical.

Which explains why conduction is unlikely when ice is placed on a freezer shelf? There is no direct contact. The ice is too cold. The shelf acts as an insulator. The ice and shelf are the same temperature.

Answers

Answer: The ice and shel are at the same temperature.

Explanation: Conduction happens when you have two objects at different temperatures touching each other, in this case, the temperature flows from the hot object to the cold one, until the equilibrium is reached (this means that both objects are at the same temperature). So, in order to conduction to happen, we need a difference in temperature and direct contact. So there are two options of the given that can be the answer: "There is no direct contact" In the sentence says that "the ice is placed on the freezer shelf", so we have direct contact between both objects. "The ice and shelf are at the same temperature" Here both objects are inside of the freezer, so we can expect that both of them are at the same temperature, hence, there is no conduction.
