Answer:
d.) Marbles 1 and 2 repel each other, but no interaction occurs with marble
Explanation:
Rubbing the glass against the silk charges the glass positively.
Assuming polarization is ignored,
●Glass won't conduct electrical charge. Therefore, acting as a insulator.
●neutral objects won't distribute it's charge when affected by charge objects in proximity. Therefore, over the marble surface, the charge remain spherically symmetrical (undisturbed)
Marble 1 is positive
Marble 2 is positive
Since marble 1 and 2 are positive, repulsion will occur.
marble 3 is neutral (still assuming polarization is ignored), therefore, no interaction with marble 1 and 2
D is the answer.
Answer: A.Validate and implement the results.
The final step in a forecasting system is to validate and implement the results. This can be similar to a presentation. After going through all the steps from the planning, researching, and gathering of data, making the forecast, validating and implementing the results will be the last thing that needs to be done.
Answer
Given,
Magnetic field, B = 0.0000193 T
speed, v = 121 m/s
mass of electron, m = 9.11 x 10⁻³¹ Kg
charge of electron, q = 1.6 x 10⁻¹⁹ C
radius of the electron path, r = ?


r = 3.64 x 10⁻⁵ m
We know frequency is inverse of time period
d = v t



t = 1.889 x 10⁻⁶ s.
now, frequency

A red apple absorbs all colors of visible light except red, so red light
is the only light left to bounce off of the apple toward our eyes.
(This is a big part of the reason that we call it a "red" apple.)
Here's how the various items on the list make out when they hit the apple:
<span>Red . . . . . reflected
Orange . . absorbed
Yellow . . . </span><span><span>absorbed
