Oliver builds a circuit connecting a light bulb to a battery with wires, leaving a gap in one of the wires. He places several ob

jects across the gap to close the loop. He wants to see which objects allow electricity to flow and turn on the light bulb. Why do some materials allow electricity to flow through while others do not?
A. Electricity will flow if the atoms in the material are bound tightly to each other.

B. Electricity will flow if the atoms in the material are bound loosely to each other.

C. Electricity will flow if the electrons are bound tightly to their atoms in the material.

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Answer:

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Explanation:

The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.

Thus, the correction for this question is "D"

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by B. What is the magni
masya89 [10]

Answer:

  B/4

Explanation:

The magnetic field strength is inversely proportional to the square of the distance from the current. At double the distance, the strength will be 1/2^2 = 1/4 of that at the original distance:

The field at twice the distance is B/4.

A kangaroo has a maximum gravitational potential energy during one jump of 770 J
KengaRu [80]

Answer:

k = 44000 N/m

Explanation:

Given the following data;

Maximum gravitational potential energy = 770 J

Elastic potential energy = 14% of 770 J = 14/100 * 770 = 107.8 J

Extension, x = 42 - 35 = 7cm to meters = 7/100 = 0.07 m

To find the spring constant, k;

The elastic potential energy of an object is given by the formula;

E.P.E = \frac {1}{2}kx^{2}

Substituting into the equation, we have;

107.8 = \frac {1}{2}*k*0.07^{2}

107.8 = \frac {1}{2}*k*0.0049

Cross-multiplying, we have;

215.6 = k*0.0049

k = \frac {215.6}{0.0049}

k = 44000 N/m
