Absolute zero (K=0 or -273.15°C) is what temperature on the Farenheit scale? a) 459.4°F b) -301.43 °F c) 233.05°F d) -40.15°F e
ANEK [815]

Answer:

e) None of these is true

Explanation:

Given that

Temperature = 0 K

We know that relationship between kelvin and Farenheit scale

\dfrac{K-273}{100}=\dfrac{F-32}{180}

Now by putting the values

\dfrac{K-273}{100}=\dfrac{F-32}{180}

\dfrac{0-273}{100}=\dfrac{F-32}{180}

So F= - 459.67°F

So we can say that 0 K is equal to  - 459.67°F.

So the our option e is correct.

What average net force is required to accelerate a 9.5 g
Nesterboy [21]

Answer:

2361 Newtons

Explanation:

From the second Newton's law of motion;

F = ma

In this case;

we are given;

Mass as 9.5 g

Initial speed as 0 m/s

Final velocity as 650 m/s

Distance is 0.85 m

Using the equation;

V² = U² + 2as

But u = 0

v² = 2as

Therefore;

a = v² ÷ 2s

  = 650² ÷ 2(0.85)

  = 248,529.40 m/s²

But;

F = ma

   = 0.0095 kg × 248,529.40 m/s²

   = 2361 Newtons

Therefore;

The average net force required to accelerate the bullet is 2361 Newtons.

15 if an object gains_ it has an electrical charge
Papessa [141]

Answer:

15. electrons

16. electrometer

18. Transformers

24. Power

Explanation:

  1. The fundamental charges in nature are electrons and protons.
  2. The electrons have negative charges and protons have positive charges.
  3. The proton with similar other protons forms the nucleus of an atom. Mostly it doesn't exist freely in nature. it is not easy to knock out a proton from an atom.
  4. Whereas, the electrons were present in the outer sphere if the nucleus of an atom.Compared to a proton, It is easy to remove an electron from an atom.
  5. So, if an object gains some electrons, it acquires some charges.
  6. The amount of such charges can be measured using a device called electrometer.
  7. The flow of electrons is associated with energy. This energy is called electrical energy and it can be converted into other forms of energy.
  8. The rate at which electrical energy is converted to some other forms of energy is called electrical power.
