When the first periodic table of the elements was published, the elements were arranged by atomic mass. Although several element

s seemed out of order, later discoveries showed the order to be correct. Which event most likely helped the development of the periodic table?
Scientists changed the atomic masses to better fit the pattern.
Scientists refused to consider other ways to organize the elements.
New technology was developed that modified the masses.
New information changed the understanding of the atom’s structure.

<span>"New information changed the understanding of the atom’s structure"

Whenever a scientific observation is made, it has to be verified and its interpretation over time may change due to understanding of the specific phenomenon. Scientists do not alter the observation in any way; instead, explanations are presented to fit the observations as best as possible.</span>

A very light ping-pong ball moving east at a speed of 4 m/s collides with a very heavy stationary bowling ball. The Ping-Pong ba
KengaRu [80]

Answer:

They experience the same magnitude impulse

Explanation:

We have a ping-pong ball colliding with a stationary bowling ball. According to the law of conservation of momentum, we have that the total momentum before and after the collision must be conserved:

where is the initial momentum of the ping-poll ball

is the initial momentum of the bowling ball (which is zero, since the ball is stationary)

is the final momentum of the ping-poll ball

is the final momentum of the bowling ball

We can re-arrange the equation as follows or

which means (1) so the magnitude of the change in momentum of the ping-pong ball is equal to the magnitude of the change in momentum of the bowling ball.

However, we also know that the magnitude of the impulse on an object is equal to the change of momentum of the object:

(2) therefore, (1)+(2) tells us that the ping-pong ball and the bowling ball experiences the same magnitude impulse:

A 45-kg pole vaulter running at 10 m/s vaults over the bar. Her speed when she is above the bar is 1.1 m/s. Neglect air resistan
Lubov Fominskaja [6]

The altitude or height of the pole vaulter as she crosses the bar is 4.04 m.

<h3>What is the height of the pole vaulter?</h3>

The height of the pole vaulter is determined from the change in kinetic energy which is equal to the potential energy at that height.

  • Potential energy = Change in kinetic energy
  • mgh = m(v - u)²/2

h = (v - u)²/2g

h = (10 - 1.1)²/2 * 9.8

h = 4.04 m.

In conclusion, the height is determined from the potential energy at that height.
