To plot: The graph between mass number (x-axis) and half-life (y-axis) of the given isotopes and find the relation between them, if any.

Answer to Problem 36R
The graph between the mass number and half-life for given isotope not shows any relation between them.
Explanation of Solution
Given:
The given table contains mass number and half life of isotopes.
Isotopes Half Lives | ||
Isotope | Mass Number | Half-Life |
Radon-222 | 222 | 4 days |
Thorium-234 | 234 | 24 days |
Iodine-131 | 131 | 8 days |
Bismuth-210 | 210 | 5 days |
Polonium-210 | 210 | 138 days |
According to the given data, the graph between the mass number and half-life is as follow:
This graph shows the X-axis as the Mass number and the Y-axis as the Half-life of isotopes. After plotting the value for the given isotope, it is observed that the isotopes points on the graph have no pattern or relation.
Conclusion:
Thus, the graph between the mass number and half-life for the given isotope does not show any relation between them.

However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.arrow_forward

The mass of each sphere is 0.09 kg. If the spheres are initially 0.10 m apart, how fast will the sphere be moving when they are 1.5 m apart?arrow_forwardpls help on allarrow_forwardpls help on thesearrow_forward

Mount Everest, Earth's highest mountain above sea level, has a peak of 8849 m above sea level. Assume that sea level defines the height of Earth's surface. (re = 6.38 × 106 m, ME = 5.98 × 1024 kg, G = 6.67 × 10 -11 Nm²/kg²) a. Calculate the strength of Earth's gravitational field at a point at the peak of Mount Everest. b. What is the ratio of the strength of Earth's gravitational field at a point 644416m below the surface of the Earth to a point at the top of Mount Everest? C. A tourist watching the sunrise on top of Mount Everest observes a satellite orbiting Earth at an altitude 3580 km above his position. Determine the speed of the satellite.arrow_forward
