2 Points<br> How did J. J. Thomson change the atomic model based on his experimental<br> results?

tester [92]

Explanation:

In 1897, J.J. ... Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. Therefore, he proposed a model of the atom which he likened to plum pudding. The negative electrons represented the raisins in the pudding and the dough contained the positive charge.

If an object falls far enough, it will reach terminal velocity. At this velocity, the force of air

love history [14]

Answer:

The object will contine to fall, but at a constant velocity. There will be no more acceleration.

Explanation: When the force of gravity is equal to the reverse force of air resistance, there will will be no net force on the falling obect. F = ma, and F (net) = 0. It will continue at the same speed until those forces become imbalanced again (such as when the force pushing up from the ground is greater than the force of gravity pulling it down). The metric term for this sudden resistance is "crash/bang/clunk/yieouch."

I NEED HELP PLEASE HELP ME

AnnZ [28]

Answer:

24000N

Explanation:

The mass of the object stays the same, regardless of its gravitational field strength. But, weight=mass*gravitational field strength.

So, the gravitational field strength on Earth is 10N. 2400*10=24000.

A scientist fixes a test charge q′ to point P and then measures the electrostatic force it experiences there. She then calculate

nordsb [41]

Answer:

<em>Correct answer: B.</em>

Explanation:

Electrostatic Field

It measures the electric effect of a charge distribution in its surroundings. If we wanted to test or measure the electric field by using a point-charge of value q', then the electric field is

$\displaystyle E=\frac{F}{q'}$

The electrostatic force between two point charges is

$\displaystyle F=\frac{k\ q_1\ q'}{r^2}$

So, the electric field is

$\displaystyle E=\frac{\frac{k\ q_1\ q'}{r^2}}{q'}$

$\displaystyle E=\frac{k\ q_1}{r^2}$

The theory shows that the electric field doesn't depend on the test charge used, i.e., if we now use q'=-q', the electric force will be of the same magnitude but in the opposite direction, thus the electric field will be the same. Let's recall the formula is used to compute the scalar value of the field, the direction must be studied separately.

Now, if we changed the test charge to another value, say 2q, the measured force will be

$\displaystyle F=\frac{k\ q_1\ 2q}{r^2}$

And the new electric field is

$\displaystyle E=\frac{k\ q_1}{r^2}$

We can see the electric field is not affected by the value of the test charge.

Finally, if we move the test charge to another location and keep the same charge, the electric force will vary and the electric field will be different.

Correct answer: B.
