Which statement is true about a polarized object?

Answers

Answer 1
Answer: The statement which is true about a polarized object would be "the number of the positive and negative charges can be the same." Polarized objects became polarized and it has its center of positive charges separated from negative charges. 
Answer 2
Answer:

Answer:

For plato users: C.The number of positive and negative charges can be the same.

On a horizontal frictionless surface a mass M is attached to two light elastic strings both having length l and both made of the same material. The mass is displaced by a small displacement Δy such that equal tensions T exist in the two strings, as shown in the figure. The mass is released and begins to oscillate back and forth. Assume that the displacement is small enough so that the tensions do not change appreciably. (a) Show that the restoring force on the mass can be given by F = -(2T∆y)/l (for small angles) (b) Derive an expression for the frequency of oscillation.

the cumulative nature of modern knowledge of physics

how physicists form explanations using logic and evidence

inductive vs. deductive reasoning

how inductive reasoning is important in the study of physics

Answers

In my opinion, the correct answer is the first one, 'the cumulative nature of modern knowledge of physics'. He is trying to say here that it is the overall knowledge of physics and of his predecessors that has helped him become the greatness that he is today. 

Evelyn learns that a sound wave can be recorded electronically as an analog signal or as a digital signal. She investigates these two signal types. She records her voice using a tape recorder, which uses an analog signal to produce sound when played back. She also records her voice using a computer, which uses a digital signal to produce sound when played back. Evelyn replays each recording 100 times.a. Describe a difference that Evelyn would most likely hear between the two recordings after being replayed 100 times.

b. Explain why the two recordings would sound different after being replayed 100 times.

Answers

a)The analog signal'spitch and frequency change each time. It is continuous in the digital signal.

What is the digital signal?

A digital signal is one in which data is represented as a series of discrete numbers.

To reduce the influence of noise in communication, a digital signal is utilized. When compared to analog signals, digital signals convey more information per unit of time.

a)Evelyn would most likely notice a difference between the two recordings after hearing them 100 times is that the analogsignal's pitch and frequency change each time. It is continuous in the digital signal.

b)After 100 replays, the two recordings would sound different since the digital signal has a greater quality throughout long-distance transmission.

When digital signals are transferred, the amount of bandwidth used is lowered.

Hence, the digital signal has a greater quality throughout long-distance transmission causing two recordings would sound different.

A cubic piece of metal measures 7.50cm on each edge. If the metal is nickel, whose density is 8.90 g/cm3, what is the mass of the cube?

Answers

mass of a cube = density * volume
volume = length of each side ^3
= 7.5*7.5*7.5 = 521.875 cm ^3
therefore mass = 8.90 g/cm3 *521.875 cm3 = 3754.69

The picture above shows 3 sets of balloons, all with a particular charge. Which of the picture(s) is true? Explain. Then explain why the other 2 pictures are incorrect. Make sure to explain all 3 sets.

Answers

Among all of the others Picture 3 is correct.

We know, Like charges repel each other whereas unlike charges attract each other, In picture 3 they are like charges (both are positive) so, we can repulsion hence, picture is correct!

In picture 1, they are unlike charges, & showing repulsion which is wrong, same In picture 2, they are like charges & showing attraction so they are wrong as well

Hope this helps!
