Answer: (a) 5Joules
(b) 10m/s
(c) 1.0kgm/s
(d) 33.3N
Explanation:
(a) P E = mass * gravity * height
= 0.1*10*5 = 5Joules
(b) All PE is converted to KE
Therefore;
KE = 1/2 * mass * velocity^2
5 = 1/2 * 0.1 * v^2
V = sqrt(100)
v = 10m/s
(c) change in momentum = mass * velocity
= 0.1 * 10
= 1.0kgm/s
(d) impulse = change in momentum
Change in momentum = force * time
1.0 = force * 0.03
Force = 1.0/0.03
Force = 33.3N
Therefore, the force acting on the egg is 33.3N
Since each light year is approximately 9 trillion kilometres, 4.80 light years is 43.2 trillion kilometres, or 43,200,000,000,000,000 metres
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.
