Yes many things can reflect xrays or gamma rays including electronics ans pretty much any other matter in the world
Answer:
450
Explanation:
total magnification = eyepiece lens x objective lens
10 x 45 = 450
Answer:
I think it is C: salinity of the water
Explanation:
Answer:
58.5 m
Explanation:
First of all, we need to find the total time the ball takes to reach the water. This can be done by looking at the vertical motion only.
The initial vertical velocity of the ball is
where
u = 21.5 m/s is the initial speed
is the angle
Substituting,
The vertical position of the ball at time t is given by
where
h = 13.5 m is the initial heigth
is the acceleration of gravity (negative sign because it points downward)
The ball reaches the water when y = 0, so
Which gives two solutions: t = 3.27 s and t = -0.84 s. We discard the negative solution since it is meaningless.
The horizontal velocity of the ball is
And since the motion along the horizontal direction is a uniform motion, we can find the horizontal distance travelled by the ball as follows:
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.
