Use the drop-down menus to answer each question. How do objects with the same charge interact? How do objects with opposite char
ValentinkaMS [17]

It's very tough to use the drop-down menus for this.  I'll just do the best I can without them.

-- Objects with the same charge repel each other with electrostatic force, and attract each other with gravity.  You can ignore the gravity because the electrostatic force is so much stronger.

-- Objects with opposite charge attract each other with electrostatic force, and also attract each other with gravity.  You can ignore the gravity because the electrostatic force is so much stronger.

-- Objects with no charge have no electrostatic force between them, and they only attract each other with gravity.

A 770 n man stands in the middle of a frozen pond of radius 10.0 m. he is unable to get to the other side because of a lack of f

Momentum is conserved throughout this scenario.

Before the man does anything, the total momentum of him and his book is zero.  So we know that it'll be zero after he throws the book.

Momentum = (mass) x (velocity)

The man gives the book (1.2 kg)x(10 m/s north) = 12 kg-m/s north
of momentum.

Since the total momentum must be zero, the man himself picks up 120 kg-m/s of momentum south.

(his mass)x(his v) = 120 kg-m/s south = (770 kg-m/s^2/9.8 m/s^2)x(V).

His velocity southward = (120 x 9.8) / (770)    m/s .

He needs to reach the shore 10m away.

Time = distance/speed

        =  (10 x 770) / (120 x 9.8) seconds

        =  6.55 seconds

Charges are pushed through an electric circuit by?
Semmy [17]

Answer:

The particles that carry charge through wires in a circuit are mobile electrons. The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field.
