Ikes teacher tells him that this process has caused each strip of tape to gain a negative electric charge. What could ike do nex

Answer:

Explanation:

Ike will need to bring positively charged object near one end of the tape, electrons in the tape act like a conductor and will be attracted to the end near the positively charged object. This leaves the other end of the tape positively charged as a result of induction. Therefore, when Ike touch the positive end of the metal rod, electrons from his body will be attracted to the positive rod and transfer onto the rod. When he remove his finger, the rod has more electrons and is will be negatively.

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)

True or false energy is always lost in a circuit
Llana [10]

Explanation:

Electrons will gain energy as they are "pushed" from different points in the circuit. This energy is then lost when the electrons flow through circuit components such as a light bulb.

What is the average power developed by a motor as it lifts a 400.-kilogram mass at constant speed through a vertical distance of
Tomtit [17]

Answer:

The average power developed by a motor is 4905 Watts.

Explanation:

The average power is given by:

P = \frac{W}{t}

Where:

W: is the work

t: is the time = 8.0 s

First, let's find the work:

W = F*d

Where:

F: is the force

d: is the displacement = 10.0 m

The force is in the vertical motion, and since the movement of the mass is at constant speed the force is:

F = mg = 400 kg*9.81 m/s^{2} = 3924 N

Hence, the average power is:

P = \frac{F*d}{t} = \frac{3924 N*10.0 m}{8.0 s} = 4905 J/s = 4905 W                    

Therefore, the average power developed by a motor is 4905 Watts.

I hope it helps you!
