The scientific knowledge was necessary for Schrödinger’s work is the discoverd of electron.
<h3>What is electron and how was it discovered?</h3>
Thomson carried out new experiments that led him to conclude that cathode rays were formed by particles that have a negative charge. Later, Thomson proved that these rays were deflected by applying an electric field. Thus, these particles were called electrons.
The discovery of the electron allowed Schrodinger to explain quantum models that are based on how electrons behave.

Answer:
Liquid has a defined volume but undefined shape
Explanation:
Explanation:
Solid has specific shape and volume
Liquid has specific volume but no specific shape
Gases have no specific volume and no specific shape
So correct answer is liquid.
Answer:
NaNO3.
Explanation:
The Na ion has one positive charge and the NO3 ion has one negative charge so the correct formula is NaNO3.

A) 0.189 N
The weight of the person on the asteroid is equal to the gravitational force exerted by the asteroid on the person, at a location on the surface of the asteroid:

where
G is the gravitational constant
8.7×10^13 kg is the mass of the asteroid
m = 130 kg is the mass of the man
R = 2.0 km = 2000 m is the radius of the asteroid
Substituting into the equation, we find

B) 2.41 m/s
In order to orbit just above the surface of the asteroid (r=R), the centripetal force that keeps the astronaut in orbit must be equal to the gravitational force acting on the astronaut:

where
v is the speed of the astronaut
Solving the formula for v, we find the minimum speed at which the astronaut should launch himself and then orbit the asteroid just above the surface:
