Compare how a positively charged object and a negatively charged object interact with a neutral object

2 answers:

3 0

A neutral is simply one which contains and equal number of positive and negative charges. So when a charged object interacts with the neutral object, it attracts the opposite charge to the side of the interaction and repels the same charge to the opposing side of the interaction. <span>+ object<span>- object</span>

Well, as far as I know, the charged objects don't interact with "neutral" objects. Unless the charged objects induce charges in the otherwise neutral objects ...

A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s656-03-02-00-00_files/i02900

Whitepunk [10]

It would be 17 m/s

If we use

V2 = V1 + a*t
Sub in 5 for v1
2m/s*2 for a
And
6 for t
That should give you the answer.

Write a numerical expression for the emissive intensity (in W/m^2.sr) coming out of a tiny hole in an enclosure of surface tempe

stiks02 [169]

Answer:

6.0 × $10^{11}$ W/ $m^{2}$

Explanation:

From Wien's displacement formula;

Q = e A $T^{4}$

Where: Q is the quantity of heat transferred, e is the emissivity of the surface, A is the area, and T is the temperature.

The emissive intensity = $\frac{Q}{A}$ = e $T^{4}$

Given from the question that: e = 0.6 and T = 1000K, thus;

emissive intensity = 0.6 × $(1000)^{4}$

= 0.6 × 1.0 × $10^{12}$

= 6.0 × $10^{11}$ $\frac{W}{m^{2} }$

Therefore, the emissive intensity coming out of the surface is 6.0 × $10^{11}$ W/ $m^{2}$ .

__________ skids occur when you suddenly press too hard on the accelerator and the drive wheels lose traction.

Fynjy0 [20]

Answer:

Power Skids

Explanation:

Power Skid like the question suggested, is a skid that occurs when you suddenly press too hard on the accelerator and the drive wheels lose traction. Power Skid is one of the 4 types of Skids. The other 3 includes;

Cornering skid

Blowout skid and

Braking skid.

Power skid occurs mostly as a result of insanely high speed and or acceleration,when the accelerator is pressed on too suddenly causing the vehicle to be driven beyond its capabilities, and then to skid, ultimately.
