The resistance of a wire which is used to power clothes dryer rank third as the area and diameter of wire is inversely proportional to the resistance of the wire. Thus, the correct option is A.

Electrical resistance is a measure of the opposition or friction to the current flow in an electrical circuit. Resistance is measured in the unit of ohms, that is symbolized by omega (Ω). Resistance of an electrical wire can be calculated by the formula:

R = (ρ×L)/A

where, R = Resistance of the wire,

ρ = Resistivity or specific resistance,

L = length of the electrical length,

A = Cross-sectional area of the electrical wire.

The resistance of a electrical conductor is dependent on the following factors including the cross-sectional area of the conductor, length of the conductor and the material of the electrical conductor.

Therefore, the correct option is A.

Answer:10

Explanation:

You have to do speed divided by time so your answers 10

Answer:

7.5 m/s

Explanation:

A red tailed hawk leaves its nest and flies 100 meters across the sky in 20 secs

Speed 1= distance/time

= 100/20

= 5m/s

When it spots a garter snake on the ground it flies 50 meters in 5 secs

Average speed= distance /time

= 50/5

= 10 m/s

Therefore the average speed of the hawk over the entire journey can be calculated as follows

= 10+5/2

= 15/2

= 7.5 m/s

Explanation:

length of pipe= 32 ft

wavelength of wave λ= 8.8 m

let f be frequency

we know velocity of wave v=λf

therefore, f=v/λ = 346/8.8 = 39.31 per second or hertz

time period = 1/f = 1/39.31 = 0.02543 seconds

The frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.

Frequency is defined as the number of repetitions of waves occurring in 1 second. Frequency is also defined as the number of cycles completed in 1 second. SI unit of frequency is Hz.

The given data in the problem is;

L is the length of pipe= 32 ft

λ is the  wavelength of wave= 8.8 m

f is the frequency=?

T is the time period=?

The frequency is fine as the ratio of the speed of wave and wavelength.,

[tex]\rm f= \frac{v}{\lambda} \\\\ \rm f= \frac{346}{8.8}\\\\ \rm f= 39.31 \ Hz[/tex]

The time period is guven as the inverse of the time period.

[tex]\rm T = \frac{1}{f} \\\\ \rm T = \frac{1}{39.31} \\\\ \rm T = 0.02543\ sec[/tex]

Hence the frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.

Explanation:

Answer:

It produces 1000Ω.

Explanation:

You have to apply Voltage formula, V = I × R :

V = I × R

6 = 0.006 × R

R = 6 ÷ 0.006

R = 1000Ω

We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that  How much resistance that allows 6V battery to produce a current of 0.006 amps is

R=1000 ohms

From the Question we are told

How much resistance allows 6V battery to produce a current of 0.006 amps?

Generally the equation for Resistance mathematically given as

[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]

R=1000 ohms

Therefore

How much resistance that allows 6V battery to produce a current of 0.006 amps is

R=1000 ohms
