Answer: Hypotheses, which are proposed explanations for scientific observations, help us properly design experiments because experiments are used to test those hypotheses. Experiments are designed based on the measurable variables defined in a given hypothesis.
Explanation: Make a list of all potential hypotheses to be tested. For each hypothesis, ask what would be true if the hypothesis were true. The experimental procedure is a step-by-step recipe for the science experiment. A good procedure contains enough detail that someone else could easily duplicate the experiment.
Hope this helps^^
Answer:
your question is incomplete.
most points by a player? most you *can* score? NBA, college, high school?
really, the possibilities are endless.
Wilt Chamberlain scored 100 points in a game.
There is no upper limit.
Displacement is simply the change in position, or the difference in the final and initial positions:
Then
(a) ∆<em>d</em> = 5 m - 0 m = 5 m
(b) ∆<em>d</em> = 1 m - (-2 m) = 1 m + 2 m = 3 m
(c) ∆<em>d</em> = 2 m - (-2 m) = 2 m + 2 m = 4 m
(d) ∆<em>d</em> = 6 m - 2 m = 4 m
Answer:
E = 124 eV
Explanation:
Given,
The frequency of the X-rays, ν = 3.0 x 10¹⁰ Hz
The formula for calculating the energy of the electromagnetic waves of a single photon of having frequency 'ν' is given by the relation
E = hν joules
Where,
h - Planck's constant (6.626 x 10⁻³⁴ Js)
Substituting the values in the above equation
E = 6.626 x 10⁻³⁴ Js x 3.0 x 10¹⁰ Hz
= 1.9878 x 10⁻²³ J
Converting it into eV
E = 1.9878 x 10⁻²³ x 6.242 x 10¹⁸ eV
= 124 eV
Therefore, the energy in electron volts of X-rays is, E = 124 eV
