Answer: D) The convective zone
Explanation: The Sun's convective zone rapidly mixes plasma within the Sun due primarily to heat transfer by convection. Convection is also the main mode of heat transfer within a pot of boiling water. So boiling water could be used to model the convective zone.
Answer:
The periodic table illustrate some of the elements from Hydrogen to Calcium
Answer:
lead with Z = 82 is transformed into Bismuth with Z = 73
The Po with Z = 84 becomes Pb with Z = 82
Explanation:
Beta decay occurs when a neutron emits an electron and an anti neutrino from the atomic nucleus, therefore the atomic number of the material increases by one unit.
Pb + e + ν → Bi
lead with Z = 82 is transformed into Bismuth with Z = 73
In alpha decay, a helium nucleus is emitted from the nucleus of the atom, therefore the atomic number decreases by two units.
Po +α → Pb
The Po with Z = 84 becomes Pb with Z = 82
This phenomenon is called the Bragg scattering. The working equation used for this is:
λ = 2dsinθ
where
λ is the wavelength and θ is the incident angle
0.240nm = 2dsin(24.5°)
Solving for d,
<em>d = 0.29 nm</em>
Answer: 129.5 m
Explanation:
310 + 115 + 25 + 68 = 518
518 / 4 = 129.5 m
i think. Sorry if this is wrong
