How many top quark lifetimes have there been in the history of the universe (i. e., what is the age of the universe divided by the lifetime of a top quark)? note that these powers of 10 follow the same rules that any exponents would follow?

Explanation:

- The mean lifetime of a top quark is of the order of

- The approximate age of the universe is 13.7 billion years, so in seconds:

So, the ratio between the age of the universe and the lifetime of a top quark is:

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
