How many coulombs of positive charge are there in 3.60 kg of plutonium, given its atomic mass is 244 and that each plutonium ato
PtichkaEL [24]

1 mole of plutonium = 244 gm

3.6 kg of plutonium = 3.6 × 1000 = 3600 gm

Number of moles = 3600 ÷ 244 = 14.754 moles

One moles of plutonium contains protons = \( 6.023 \times {10}^{23} \times 94 \)

Total number of protons in 14.754 moles = \( 6.023 \times {10}^{23} \times 94 \times 14.754 \)

Total number of protons in 14.754 moles = \(8353.15 \times {10}^{23}\)

Total Positive charge = \(8353.15 \times {10}^{23} \times 1.6 \times {10}^{-19}\)

Total positive charge = \(13365.04 \times {10}^{4}\) C

A cart traveling at 0.3 m/s collides with stationary object. After the collision, the cart rebounds in the opposite direction. T
miv72 [106K]

Answer:

C.   In the first collision has twice the momentum as when it stays still ( second colllions)

Explanation:

To see which statement is correct, it is best to solve the problem, the momentum is equal to the variation of the moment

     I = Δp = m vf - m v₀

     I = m (vf -v₀)

Case 1. In car bounces, the initial speed is 0.3 m / s, say that this direction is positive, when the magnitude of the speed bounces it remains constant, but its direction is reversed (vf = -0.3 m / s)

    I₁ = m (-0.3 - 0.3)

    I₁ = -0.6 m

Case 2. The expensive one that still after the crash so its speed is zero (vf = 0)

    I₂ = m (0 - 0.3)

    I₂ = -0.3 m

Let's calculate the relationship between the two impulses

     I₁ / I₂ = -0.6m / -0.3m

     I₂ / I₂ = 2

When it bounces it has twice the momentum as when it stays still

Now let's analyze the answers:

A.   False The momentum changes

B. False. The momentum is less in the second collision

C. True.  The momentum is double in this collision

D. False. Can be calculated, because the mass is the same throughout the exercise and is eliminated in the equations

E. False.  When they say bounces it implies the same speed with the opposite direction
