Answer:
Ranking the cars based on magnitude of momentum <em>(largest to smallest)</em>:
1. Purple, Light Blue
2. Red, Yellow, Blue
3. Green
Explanation:
Based on the given parameters ( mass and velocity), we can calculate the momentum of the various cars using the formula:
momentum = mass x velocity
1. Momentum of red car = 1000kg x 10m/s = 10,000Kgm/s
2. Momentum of Yellow car = 2000kg x 5m/s = 10,000Kgm/s
3. Momentum of blue car = 500kg x 20m/s = 10,000Kgm/s
4. Momentum of light blue car = 1000kg x 20m/s = 20,000Kgm/s
5. Momentum of green car = 500kg x 10m/s = 5,000Kgm/s
6. Momentum of purple car = 4000kg x 5m/s = 20,000Kgm/s
Hence,
Ranking the based on magnitude of momentum <em>(largest to smallest)</em> we have:
1. Purple, Light Blue
2. Red, Yellow, Blue
3. Green
Answer:
As we know,
work = 77 N × 1.5m
therefore 115.5 J work was done
Answer: 129.5 m
Explanation:
310 + 115 + 25 + 68 = 518
518 / 4 = 129.5 m
i think. Sorry if this is wrong

Answer:
Explanation:
The electrostatic attraction between the nucleus and the electron is given by:
(1)
where
k is the Coulomb's constant
Ze is the charge of the nucleus
e is the charge of the electron
r is the distance between the electron and the nucleus
This electrostatic attraction provides the centripetal force that keeps the electron in circular motion, which is given by:
(2)
where
m is the mass of the electron
v is the speed of the electron
Combining the two equations (1) and (2), we find
And solving for v, we find an expression for the speed of the electron:
