<span>In an atom electrons are negatively charged particles , protons are positively charged particles and neutrons as their name suggests have no charge . So if an atom has excess of negative charge it means that it has extra electrons This means answer is 4 more electrons than protons Cause this means that there are no protons to balance out the negative charge of those 4 extra electrons which creates negative four charge on atom</span>

NeTakaya

Answer:

it will move towards the object's magnetic south

Explanation:

The compass pints towards the earth geographic north because the magnetic south of the earth's magnetic field is located in there, if you placed such compass neaar the piece of ferromagnetic material, the magnetic field produced by the magnet will make the compass needle point towards its south magnetic pole, in the same fashion as it points to the earth's magnetic south. It will point to the object's south pole because the magnetic field will be stronger than the earth's (which is weak) that is because of the way magnetism works, opposite poles are attracted and similar poles will tend to separate from each other

A plane traveling horizontally at 120 ​m/s over flat ground at an elevation of 3610 m must drop an emergency packet on a target
allsm [11]

Answer:

Explanation:

Horizontal displacement

x = 120 t

Vertical position

y = 3610 - 4.9 t²

y = 0 for the ground

0 = 3610 - 4.9 t²

t = 27.14 s

This is the time it will take to reach the ground .

During this period , horizontal displacement

x = 120 x 27.14 m

= 3256.8 m

So packet should be released 3256.8 m before the target.

If you were trying to describe the difference between power and work you could say...?
Paha777 [63]

Answer:

Look to the explanation

Explanation:

<u><em>Work done</em></u> is  is the energy transferred to or from an object by means

of a force acting on the object.

Work is positive if energy transferred to the object, and  work is

negative if energy transferred from the object.

<em>Work = Force in the direction motion of object × its displacement</em>

W=F*s

The SI unit of the work is joule (J)

<u><em>Power</em></u> is the rate of work

<em>Power = work done ÷ time taken</em>

Power = \frac{F*s}{t}

Displacement (s) ÷ time (t) = velocity (v)

<em>Power = Force × velocity</em>

P=F*v

The SI unit of the power is watt (w)
