How well a material conducts current is an internal factor affecting resistance.A shorter wire will allow electricity to move through at a higher rate than a longer wire.When a light is first switched on, the light bulb's filament has a lower resistance than after it gives off light for awhile.Superconductors have no measurable resistance.If you double the thickness of a wire, you cut the resistance in half.A short, thick, cold wire is the best conductor.

False

Thickness, length, and temperature are internal factors that affect resistance.The resistance in a wire with less thickness is less.The higher the temperature of the conductor, the lower the resistance.If you double the length of a wire, you cut the resistance in half.

The moon is 384,403 km from the earth how many quarters laid end to end it would take to reach the moon if a quarter has a diame
diamong [38]

Answer:

Distance from the moon= dm= 384,403km

A quarter diameter= dq= 2.3 cm= 0.000023km

No of quarters= 16,713,173, 913

To convert cm into km divide cm by 100 and then by 1000

as

1m= 100cm

1km= 1000m

Therefore

2.3/100= 0.023 m

And

0.023/1000= 0.000023 km

Dividing the distance from the moon by the diameter of the quarter laid end to end would give the number of the quarters needed.

No. of quarters= Distance from the moon/ Diameter of the quarter

                             = 384,403km/0.000023 km

                             =       16,713,173,913.043

Rounding  16,713,173,913.043 gives 16,713,173,913 quarters

A pupil wants to find the density of an oil. She uses a chemical balance which measures to the nearest gram (g). She places an e
scoray [572]

Answer:

2.29g/cm3.

Explanation:

The following data were obtained from the question.

Mass of the oil = 172g

Volume of oil = 75cm3

Density =..?

Density of a substance is simply defined as the mass of the substance per unit volume of the substance. It is represented mathematically as:

Density = Mass /volume

With the above formula, we can calculate the density of the oil as shown below:

Density = Mass /volume

Density = 172g/75cm3

Density = 2.29g/cm3.

Therefore, the density of the oil is 2.29g/cm3.

Momentum is a measure of the<br> of an object.<br> Which term accurately completes the sentence?
RideAnS [48]

Answer:

Momentum is define as the product of the mass and velocity of a body. It is measured in Kgm/s.

Explanation:

Momentum is the product of mass and velocity of an object. When an object or a body of mass 'm' is moving with velocity 'v', then its momentum can be determined as;

momentum (P) = mass × velocity

i.e            P = m × v

                  = mv

It is measured in Kgm/s.

The change in momentum of a body is referred to as its impulse (Ft).

ΔP = m(v - u) = Ft

Where: P is the momentum of the object, m is its mass, v is its final velocity, u is the initial velocity, F is the force and t is the time in which the force acts.
