Answer:
Freudian
Explanation:
Answer: The correct answer is Option B.
Explanation:
We are given a radioisotope which is unstable in nature. For this isotope to become stable, it has to undergo radioactive decay. There are various processes by which a radioisotope may decay:
1. Alpha decay: In this decay process, a heavier nuclei decays into lighter nuclei. The particle released is alpha particle.
2) Gamma decay: In this decay process, an unstable nuclei gives excess energy by a process of spontaneous electromagnetic process. This decay process releases .
3) Beta-plus decay: In this decay process, a neutron gats converted into a proton and an electron. The particle released is
4) Beta-minus decay: In this decay process, a proton gets converted into a neutron and an electron neutrino which is known as a positron particle. This is also known as -decay.
Radium-226 nuclei undergoes alpha decay to form Radon-222 nuclei by releasing alpha-particle.
Hence, the answer is Option B.

B. Infrared waves
C. X rays
D. Cosmic rays
B. a faster wave velocity.
C. the same frequency.
D. a longer wavelength.
Buoyant force is equal to the weight of the total amount of liquid displaced by an object when submerged partially or completely in the fluid. This means that if an object that has a volume of 2m³ has 50% (1m³) of its volume submerged in water, the buoyant force will be equal to the weight of 1 m³ of water, this is about 1000kg.
With this in mind, the buoyant force will be equal to the weight of the amount of fluid that has the same total volume as the object when the object is completely submerged, this is to say, it has its total volume under the fluid.
the motion of the star
the temperature of the atmosphere of the star
all of the above
Answer:
all of the above
Explanation:
The spectrum of the star is is used to study its composition, motion and surface temperature. The absorbed or emitted wavelength indicates the elements present. The peak wavelength determines the surface temperature of the star using Wein's law. Peak wavelength is inversely proportional to temperature. The red-shift or blue shift indicates whether the star is moving away or towards us.
