A 2.8-carat diamond is grown under a high pressure of 58 × 10 9 N / m 2 .
Rzqust [24]

Answer:

a)  ΔV = 2,118 10⁻⁸ m³   b)  ΔR= 0.0143 cm

Explanation:

a) For this part we use the concept of density

    ρ = m / V

As we are told that 1 carat is 0.2g we can make a rule of proportions (three) to find the weight of 2.8 carats

    m = 2.8 Qt (0.2 g / 1 Qt) = 0.56 g = 0.56 10-3 kg

   

    V = m / ρ

    V = 0.56 / 3.52

    V = 0.159 cm3

We use the relation of the bulk module

    B = P / (Δv/V)

    ΔV = V P / B

    ΔV = 0.159 10⁻⁶ 58 10⁹ /4.43 10¹¹

    ΔV = 2,118 10⁻⁸ m³

b) indicates that we approximate the diamond to a sphere

    V = 4/3 π R³

For this part let's look for the initial radius

    R₀ = ∛ ¾ V /π

    R₀ = ∛ (¾ 0.159 /π)

    R₀ = 0.3361 cm

Now we look for the final volume and with this the final radius

    V_{f} = V + ΔV

    V_{f} = 0.159 + 2.118 10⁻²

    V_{f} = 0.18018 cm3

    R_{f} = ∛ (¾ 0.18018 /π)

    R_{f} = 0.3504 cm

The radius increment is

    ΔR = R_{f} - R₀

    ΔR = 0.3504 - 0.3361

    ΔR= 0.0143 cm

The fusion of deuterium and hydrogen is shown in the equation. fill in the missing number.
stellarik [79]

Answer:

= 2

Explanation:

During nuclear fusion, two lighter nuclei of elements combine to form heavy nucleus and also energy is released;

During the process of hydrogen fusion a nucleus of deuterium is formed from two protons with emission of a neutrino.

In this case deuterium fuses with hydrogen nuclei to form helium-3 and also release energy.

That is;

2/1 H + 1/1 H = 3/1 He + energy

2 Jim keeps a can on the ramp. The can
IceJOKER [234]

Answer:

The description of the statement is summarized throughout the explanation section below.

Explanation:

  • The layer of the ramp must've been harsh, which exacerbated the toy movement to occur gradually. This same friction force was indeed starting to function on the remote control car as well as trying to stop that one to react quickly.
  • Jim does have to simplify the exterior including its ramp by scrubbing or greasing to overcome impact as well as make driving travel quicker.
