A). No. The entire poster is already covered with atoms,
but they're too small to see.
B). No. What's "life-size" of an atom ? It's too small to see,
and that's the whole problem.
D). No. Atoms are too small to see even with a microscope.
C). Yes ! A model of an atom, big enough to see, would help
get <em><u>some</u></em> of the important ideas across.
Answer:
K = 1.29eV
Explanation:
In order to calculate the kinetic energy of the proton you first take into account the uncertainty principle, which is given by:
(1)
Δx : uncertainty of position = 2.0pm = 2.0*10^-12m
Δp: uncertainty of momentum = ?
h: Planck's constant = 6.626*10^-34 J.s
You calculate the minimum possible value of Δp from the equation (1):
The minimum kinetic energy is calculated by using the following formula:
(2)
m: mass of the proton = 1.67*10^{-27}kg
in eV you have:
The kinetic energy of the proton is 1.29eV
Answer:
The color you get for mixing red and yellow is orange.

Answer:
F1=26N and F2=09N ..this is from the two simultaneously equations
Answer:
2.91 x 10¹² sec
Explanation:
d = distance of nearest star, Proxima Centauri = 4.3 ly = 4.3 x 9.46 x 10¹⁵ m
v = speed of new horizon probe = 14 km/hr = 14000 m/s
t = time taken for the new horizon probe to reach nearest star, Proxima Centauri = ?
Using the equation
d = v t
Inserting the values given
4.3 x 9.46 x 10¹⁵ = (14000) t
t = 2.91 x 10¹² sec
