The answer for this problem would be:
Assuming non-relativistic momentum, then you have: 
ΔxΔp = mΔxΔv = h / (4) 
Δv = h / (4πmΔx) 
m ~ 1.67e-27 h ~ 6.62e-34,Δx = 4e-15 --> 
Δv ~ 6.62e-34 / (4π * 1.67e-27 * 4e-15) ~ 7,886,270 m/s ~ 7.89e6 m/s 
That's about 1% of the speed of light, the assumption that it's non-relativistic.

the reason the moon does not crash into the earth is that the group of answer choices moon has less mass than the earth. moon ha
lora16 [44]

The moon's mass is only outnumbered by Earth's mass, which is 81 times greater. This indicates that while it moves in a circle, the circle is substantially smaller than usual. The core of the circle that the Earth revolves around is really inside the planet.

In space, there is gravity. It is gravity that makes the moon orbit. Everything in orbit, including the moon, is falling freely. That entails letting gravity operate as it pleases. Because you continually missing the object you are orbiting, an orbit is like a fall that never makes it to the earth; by the time you arrive at the spot where the object was, you have overshot, and it is now behind you.

In both a dry cell and a wet cell battery, what causes the production of an electrical current.
koban [17]

Answer:

a. chemical reaction

Explanation:

In both a dry and wet cell battery, electric currents are produced through chemical reactions.

Both cells are together called electrochemical cells.

  • In these cells, chemical reactions produce an electric current.
  • They are devices that converts chemical energy into electrical energy
  • The reactions here are spontaneous redox reactions.
  • This causes the current to flow on their own in the circuit.
