Carbon-12 contains 6 protons and 6 neutrons. The radius of the nucleus is approximately 2.7 fm (femtometers) and the radius of t
Slav-nsk [51]

Explanation:

Let us assume that volumes is equal to spheres  volume of nucleus.

fm = femto meter = 10^{-15}

pm = pico meter = 10^{-12}

Hence, calculate the volume as follows.

          V = \frac{4}{3} \times \pi \times r^{3}

              = \frac{4}{3} \times 3.14 \times (2.7)^{3}

              = 82.4481 fm^{3} (cubic femtometers)

or,          = 82 fm^{3}

Now, we will calculate the volume of the atom as follows.

          V = \frac{4}{3} \times \pi \times r^{3}

             = \frac{4}{3} \times 3.14 \times (70)^{3}

             = 1436758.4 pm^{3} (cubic picometers)

thus, we can conclude that volume of the nucleus is 82 fm^{3}  and volume of the atom is 1436758.4 pm^{3}.

When the temperature of a gas changes, it's volume decreases from 12 cm3 to 7 cm3 if the final temperature is measured to be 18°
ElenaW [278]

Answer:

The initial temperature is 499 K

Explanation:

Step 1: Data given

initial volume = 12 cm3 = 12 mL

Final volume = 7 cm3 = 7mL

The final temperature = 18 °C = 291 K

Step 2: Calculate the initial temperature

V1/T1 = V2/T2

⇒with V1 = the initial volume = 0.012 L

⇒with T1 = the initial volume = ?

⇒with V2 = the final volume 0.007 L

⇒with T2 = The final temperature = 291 K

0.012 / T1 = 0.007 / 291

0.012/T1 = 2.4055*10^-5

T1 = 0.012/2.4055*10^-5

T1 = 499 K

The initial temperature is 499 K

How do you calculate net force?
bogdanovich [222]
How to find net force

The net force is the vector sum of all forces act upon an object.

The formula to calculate net force is Fnet = ma
where the net force is equal to the mass of an object (in Kg) multiplied by the acceleration of the object (in meters per second squared)

You may also calculate the net force acting upon an object with Fnet = Fa + Ff
where the net force is equal to the sum of the applied force and the force of friction.


hope that helped
