An object is placed at O ona number line. It moves 3 units to the right, then 4 units to the left, and then 6 units to the right. What is the displacement of the object?

You have a displacement of 5 units to the right.

Explanation:

First you go three to the right which lands on the 3 mark. Then you move it 4 to the left which substracts 4, landing the object at -1. Finally you move 6 to the right, and you finish at marker 5. Since displacement is not total distance but just final distance from the start point directly to end point, it is only a displacement of 5.

I think it would be +5

Explanation:

I looked on a number line and started at 0.

I then moved the object 3 units to the right and got 3.

I then moved the object 4 units the the left and got -1.

I then moved the object 6 units to the right and my final answer was positive 5. (+5 or just 5)

I hope I was right and helped

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
