Answer:
The neutron can be found in the nucleus of the atom with the proton.
Answer: 4.675×10^-6 m
Explanation: this is a question under the pattern gotten from an interference experiment.
The formulae below defines the experiment given
y = Rmλ/d
Where y = distance between the center fringe and any other fringe in the pattern = 8cm = 0.08m
m = position of fringe = 1 ( this is because we have only one central band)
λ = wavelength of light used for experiment = 680nm = 6.8×10^-7m
d = width of slit =?
R = distance between slits and screen = 5.5 cm = 0.055m
By substituting the parameters, we have that
0.08 = 0.055 × 1 × 6.8×10^-7/d
By cross multiplying, we have that
0.08 × d = 0.055 × 1 × 6.8×10^-7
d = 0.055 × 1 × 6.8×10^-7/ 0.08
d = 3.74 × 10^-7/ 0.08
d = 46.75×10^-7
d = 4.675×10^-6 m

Answer:
Explanation:
This is pretty easy to calculate when you realize that the mass of the water displaced is equal to the mass of the object floating in it.
Take an iceberg of volume V. It has density d_i. So its total mass is V*d_i = m.
Now, it is displacing 90% of its volume. The sea water has a d_w. The total mass of water displaced is 0.9 * V * d_w, and it equals the mass of the iceberg, V*d_i.
Divide both sides by V. You get 0.9 * d_w = d_i. Now we just have to solve for d_w. Dividing both sides by 0.9, you get d_w = d_i/0.9.
