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.

A bowling ball and a bag of potato chips are dropped at the same time from a tall tower on Earth. What happens?
Digiron [165]

Answer:

A bowing ball will hit the Earth first before potatoes chips.

Explanation:

While dropping , a bag of potatoes will experience air resistance. A bowing ball also experience air resistances too but it is not affected by it because it has a bigger weight that affect air resistance than potatoes chips. Potatoes chips is affected because it's weight is light and cannot affect air resistance.

A wire 95.0 mm long is bent in a right angle such that the wire starts at the origin and goes in a straight line to x = 40.0 mm
qaws [65]

Answer:

0.1040512455 N

36.03^{\circ}\ or\ 323.97^{\circ}in\ CCW\ direction

0.05925 N

29.74^{\circ}\ or\ 330.26^{\circ}in\ CCW\ direction

Explanation:

I = Current

B = Magnetic field

Separation between end points is

l=\sqrt{40^2+55^2}\\\Rightarrow l=68.00735\ mm

Effective force is given by

F=IlB\\\Rightarrow F=5.1\times 68.00735\times 10^{-3}\times 0.3\\\Rightarrow F=0.1040512455\ N

The force is 0.1040512455 N

tan\theta=\dfrac{55}{40}\\\Rightarrow \theta=tan^{-1}\dfrac{55}{40}\\\Rightarrow \theta=53.97^{\circ}

The angle the force makes is given by

\alpha=\theta-90\\\Rightarrow \alpha=53.97-90\\\Rightarrow \alpha=-36.03^{\circ}\ or\ 323.97^{\circ}in\ CCW\ direction

The direction is 36.03^{\circ}\ or\ 323.97^{\circ}in\ CCW\ direction

F=IlB\\\Rightarrow F=4.9\times \sqrt{20^2+35^2}\times 10^{-3}\times 0.3\\\Rightarrow F=0.05925\ N

The force is 0.05925 N

tan\theta=\dfrac{35}{20}\\\Rightarrow \theta=tan^{-1}\dfrac{35}{20}\\\Rightarrow \theta=60.26^{\circ}

\alpha=\theta-90\\\Rightarrow \alpha=60.26-90\\\Rightarrow \alpha=-29.74^{\circ}\ or\ 330.26^{\circ}in\ CCW\ direction

The direction is 29.74^{\circ}\ or\ 330.26^{\circ}in\ CCW\ direction

The brakes on a truck fail as it approaches a car stopped at a red light. Use Newton’s first and second law of motion to explain
PolarNik [594]

newtons first law states that a object in motion will stay in motion unless acted on by an outside force and an object at rest will stay at rest for the same reason. the force of a moving object is equal to its mass times its acceleration.
