The decay rate of Americium-241 in inverse gigaseconds is approximately 7.309 x 10⁻¹⁸ Gs⁻¹.
The decay rate of Americium is typically expressed in terms of its half-life, which is the time it takes for half of the radioactive substance to decay. The half-life of Americium-241, for example, is approximately 432.2 years.
To determine the decay rate in inverse gigaseconds (Gs⁻¹), we need to convert the half-life from years to gigaseconds.
1 year is equivalent to 3.16888 x 10⁻¹⁷ gigaseconds (Gs). Therefore, the half-life of Americium-241 is approximately 1.3684 x 10¹⁶ Gs.
The decay rate is the reciprocal of the half-life, so the decay rate of Americium-241 in inverse gigaseconds (Gs⁻¹) would be approximately 7.309 x 10⁻¹⁸ Gs⁻¹.
Therefore, the decay rate of Americium-241 in inverse gigaseconds is approximately 7.309 x 10⁻¹⁸ Gs⁻¹.

an object is dropped from a cliff. after 3 seconds, its acceleration is _____ m/s 2
According to the question, The acceleration of an object in free fall near the surface of the Earth is approximately 9.8 m/s².
When an object is dropped from a cliff, it experiences gravitational acceleration directed towards the Earth. This acceleration is constant and equal to the acceleration due to gravity, which is approximately 9.8 m/s² near the surface of the Earth. Therefore, after 3 seconds, the acceleration of the object will still be approximately 9.8 m/s². The acceleration remains constant unless other forces, such as air resistance, come into play. This is because the acceleration due to gravity remains constant unless other forces, such as air resistance, significantly affect the motion.
