Explanation:
Answer: 2045
Explanation:
Given
We had sent a radio signal to advance civilization in 2006 which is 39 light-years away i.e. time taken by light to reach reticuli star system is 39 years.
So, it will arrive the destination in the year 
Answer:
K = 13448.64eV
Explanation:
(a) In order to calculate the kinetic energy of the electrons, to "see" the atom, you take into account that the wavelength of the electrons must be of the order of the resolution required (0.010nm).
Then, you first calculate, by using the Broglies' relation, the momentum of the electron associated to a wavelength of 0.010nm:
(1)
p: momentum of the electron
h: Planck's constant = 6.626*10^-34 Js
λ: wavelength = 0.010nm
You replace the values of the parameters in the equation (1):

With this values of the momentum of the electron you can calculate the kinetic energy of the electron by using the following formula:
(2)
m: mass of the electron = 9.1*10^-31 kg

In electron volts you obtain:

The kinetic energy required for the electrons must be, at least, of 13448.64 eV
F = ma
F = (6kg) (3.5m/s2)
F = 21 N
Answer:
b.) the diverge in incident beam of light
Explanation:
A lens refers to any refracting surface. The manner in which a lens is curved tells whether it is a concave(diverging) lens or a convex (converging) lens.
A convex lens is thicker at the center than at the edges. It makes light to converge at a point.
A concave lens is is thinner at the center than at the edges. It makes light to appear to diverge from a point, hence the answer above.
