Answer:

, pfx = pix + Jx.

Explanation:

The momentum principle tells us that impulse transfers momentum to an object.

If an object has 2 kgm/s of momentum, a 1 kgm/s impulse delivered to the object

increases its momentum to 3 kgm/s. That is, pfx = pix + Jx.

Just as we did with energy, we can represent this “momentum accounting” with a

momentum bar chart. For example, the bar chart of FIGURE 11.6 represents the ball

colliding with a wall in Figure 11.4. Momentum bar charts are a tool for visualizing

an interaction

How do you work out how many atoms there are in a isotope?
GalinKa [24]
206Pb = 1.342 x10^22 atoms 

<span>To find the number of atoms, you must first find the number of moles. If 238U is 238.029g/mol, and we have 1.75 grams, how many moles is that? 1.75 divided by 238.029 = 0.007352045 moles. To find the number of atoms in 0.007352045 moles, you multiply by a mole: </span>
<span>0.007352045 x 6.02 x 10^23 = 4.426 x10^21 atoms. </span>

<span>Same procedure for 206Pb: </span>
<span>4.59 divided by 205.97446 = 0.022284316 moles </span>
<span>0.022284316 x 6.02 x 10^23 = 1.342 x10^22 atoms. </span>

<span>Hope that helps you!

Sheila weighs 60 kg and is riding a bike. Her momentum on the bike is 340 kg • m/s. The bike hits a rock, which stops it complet
Vikki [24]

Answer:

v₂ = 5.7 m/s

Explanation:

We will apply the law of conservation of momentum here:

Total\ Initial\ Momentum = m_{1}v_{1} + m_{2}v_{2}\\

where,

Total Initial Momentum = 340 kg.m/s

m₁ = mass of bike

v₁ = final speed of bike = 0 m/s

m₂ = mass of Sheila = 60 kg

v₂ = final speed of Sheila = ?

Therefore,

340\ kg.m/s = m_{1}(0\ m/s) + (60\ kg)v_{2}\\v_{2} = \frac{340\ kg.m/s}{60\ kg}\\\\

<u>v₂ = 5.7 m/s </u>
