When a charged body is brought close to an uncharged body without touching it, a(n) _______________ charge may result on the uncharged body. When a charged body is brought into contact with an uncharged body and then is removed, a(n) _______________ charge may result on the uncharged body.

Answers

Explanation:

When a charged object is brought near a neutral object without touching each other a charge arises on the neutral object. This method of charge development is known as induced charge.

On the other hand, when a charged object touches a neutral object and then the charged object is removed will lead to the development of a charge on the neutral object. This charge is known as residual charge.

Thus, we can conclude that when a charged body is brought close to an uncharged body without touching it, an induced charge may result on the uncharged body. When a charged body is brought into contact with an uncharged body and then is removed, a residual charge may result on the uncharged body.

What is one property of a wave that determines how much it will diffract when it encounters an obstacle?-speed
-amplitude
-polarization
-wavelength

Suppose two waves collide, and the temporary combined wave that results is smaller than the original waves. What term best describes this interaction?
-diffraction
-destructive interfernce
-standing wave formation
-constructive interfernce

The formation of a standing wave requires
-the traveling of a wave for a long distance
-constructive interference between two waves of slightly different frequencies
-that refraction and diffraction occur at the same time in a wave
-interference between incoming and reflected waves

Answers

1) D  -wave length 
2) B-destructive interference 
3)D -interference between incoming and reflective waves

a man exerts 3000.00N of force to push a car 35.00 meters in 90.00 seconds.... 1. what is the work done 2.what is the power generated

Answers

1).  Work = (force) x (distance)

Work = (3,000 newtons) x (35 meters) = 105,000 newton-meters = 105,000 joules

2).  Power = (work) / (time)

Power = (105,000 joules) / (90 seconds)
                                         = 1,166-2/3 joules per second = 1,166 and 2/3 watts .

Note:
That's no ordinary man.
1,166 watts is the same as roughly 1.6 horsepower.
Not too many people can sustain 1 horsepower or more for 90 seconds.
