A radioactivenuclide'sprobability of decay per unit time is known as its decayconstant, which is expressed in units of s1 or a1. As a result, as shown by the equation dP/P dt =, the number of parent nuclides P declines with time t. Nuclearforces are about 1,000,000 times more powerful than electrical and molecularforces in their ability to bind protons and neutrons. The strength of the bonds holding the radioactive element are likewise indifferent to the decayprobabilities and's, in addition to being unaffected by temperature and pressure. The decay constant is related to the nuclide's T 1/2 half-life by T 1/2 = ln 2/.
Because composed of photons, which have neither mass nor electric charge and, as a result, penetrates much further through matter than either alpha or beta radiation.
Answer:As the Earth orbits the Sun, the tilt of Earth's axis stays lined up with the North Star. The North Pole is tilted towards the Sun and the Sun's rays strike the Northern Hemisphere more directly in summer. ... The tilt of Earth's axis points away from the Sun.
