Sara and Greg built an electromagnet in science class. They wrapped 50 turns of copper wire around an iron nail and hooked the ends of the wire to a 1.5 volt battery. They picked up 15 paper clips with their electromagnet, but they want to make it stronger. What should they do?

Answers

Answer 1

Answer: C) Wrap more turns of wire around the nail.

Explanation:

One of the main determinants of the strength of a magnet is the number of rounds of wire around the magnet. This is because, the more wire there is, the more electricity will pass through and the more powerful the magnet will become.

They should therefore wrap more turns of wire around the nail so that more electricity can flow from the battery. This will make their magnet stronger and enable it to pick up more paper clips.

Give an example of developmental psychology when the individual is in college

Answers

The correct answer to this open question is the following.

An example of developmental psychology when the individual is in college would be this.

Personality development is my example of how people change when they enter college.

Let's have in mind that developmental psychology is the field of psychology that studies the way people grow and change during life.

Psychologists not only focus on physical and evident changes from high school to college, but they focus on the mental, emotional, and social changes.

When entering college, the student aspires to be respected and attract a different kind of people. Not only on the emotional level to have a relationship, but on the influence level, trying to be recognized above the others.

That is why in college, students try to be more mature, appear more intellectually interesting, and want to get to a place of recognition and admiration among a fierce competition of personalities.

The diagram shows the length and width of a cell phone, and the length of a larger
version of the same brand of cell phone.
2.6 in.
5.4 in.
6.21 in.
The lengths and widths of the two cell phones are proportional. What is the width,
in inches, of the larger version of the cell phone?

Answers

Answer:

The width of the bigger phone is 2.99 in

Explanation:

Given

[tex]W_1 = 2.6in[/tex]

[tex]L_1 = 5.4in[/tex]

[tex]L_2 = 6.21in[/tex]

See attachment for the measure of cell phones

Required

Determine the width of the bigger version (L2)

To do this, we make use of the following equivalent ratios.

[tex]L_1 : W_1 = L_2 : W_2[/tex]

This gives:

[tex]5.4\ in : 2.6\ in : 6.21\ in : W_2[/tex]

Express as fractions

[tex]\frac{5.4\ in}{2.6\ in} = \frac{6.21\ in}{W_2}[/tex]

[tex]\frac{5.4}{2.6} = \frac{6.21\ in}{W_2}[/tex]

Make W2 the subject

[tex]W_2 = \frac{6.21 * 2.6\ in}{5.4}[/tex]

[tex]W_2 = \frac{16.146\ in}{5.4}[/tex]

[tex]W_2 = 2.99\ in[/tex]
