a tungsten and coil has a resistance of 12 ohm at 15 degree celsius is the temperature coefficient of resistance of tungsten is 0.004 calculate the equal resistance at 80 degree Celsius​

Answers

Answer:

The resistance of the tungsten coil at 80 degrees Celsius is 15.12 ohm

Explanation:

The given parameters are;

The resistance of the tungsten coil at 15 degrees Celsius = 12 ohm

The temperature coefficient of resistance of tungsten = 0.004/°C

The resistance of the tungsten coil at 80 degrees Celsius is found using the following relation;

R₂ = R₁·[1 + α·(t₂ - t₁)]

Where;

R₁ = The resistance at the initial  temperature = 12 ohm

R₂ = The resistance of tungsten at the final temperature

t₁ = The initial temperature = 15 degrees Celsius

t₂ = The final temperature = 80 degrees Celsius

α = temperature coefficient of resistance of tungsten = 0.004/°C

Therefore, we have;

R₂ = 12×[1 + 0.004×(80 - 15)] = 15.12 ohm

The resistance of the tungsten coil at 80 degrees Celsius = 15.12 ohm.

A car leaves the pit after a refueling stop and accelerates uniformly to a speed of 62.2 m/s in 5.0 s to rejoin the race. What is the car's acceleration during this time?

Answers

Answer:

The car's acceleration is: a = 12.44 [m/s²]

Explanation:

To solve this problem we must use the following equation of kinematics.

v_(f) = v_(o)+a*t

where:

Vf = final velocity = 62.2 [m/s]

Vo = initial velocity = 0 (because the car stars from the rest)

a = acceleration [m/s²]

t = time = 5 [s]

62.2 = 0 + a*5

a = 12.44 [m/s²]

Paradigms is a pattern or a model. They shift as a change in a way of thinking to another conclusion. After an amount of time they switch/shift into another pattern/position. 

The peak intensity of radiation from Star Beta is 350 nm. What is the average surface temperature of Star Beta rounded to the nearest whole number? 121 K 6,547 K 8,285 K 10,348 K

Answers

Wien's Displacement Law is:
peak x surface temperature = 2.898 x 10^-3 m K

So,
surface temperature = 2.898 x 10^-3 m K / peak = 2.898 x 10^-3 m K / 350 x 10 -9 m
surface temperature = 8280 K

The closest to the choices is 8285 K.

Answer:

8285 K.
