QUES: According to conservation of energy, energy can neither be created (produced) nor destroyed by itself. It can only be transformed. The total inflow of energy into a system must equal the total outflow of energy from the system, plus the change in the energy contained within the system. Energy is subject to a strict global conservation law; that is, whenever one measures (or calculates) the total energy of a system of particles whose interactions do not depend explicitly on time, it is found that the total energy of the system always remains constant.
whose interactions depend explicitly on time?

ANS: unanswerable

QUES: Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology, epistemology, and character of space and time. While such ideas have been central to philosophy from its inception, the philosophy of space and time was both an inspiration for and a central aspect of early analytic philosophy. The subject focuses on a number of basic issues, including whether or not time and space exist independently of the mind, whether they exist independently of one another, what accounts for time's apparently unidirectional flow, whether times other than the present moment exist, and questions about the nature of identity (particularly the nature of identity over time).
What was the study of space and time inspired by?

QUES: In 1928, Laemmle, Sr. made his son, Carl, Jr. head of Universal Pictures as a 21st birthday present. Universal already had a reputation for nepotism—at one time, 70 of Carl, Sr.'s relatives were supposedly on the payroll. Many of them were nephews, resulting in Carl, Sr. being known around the studios as "Uncle Carl." Ogden Nash famously quipped in rhyme, "Uncle Carl Laemmle/Has a very large faemmle." Among these relatives was future Academy Award winning director/producer William Wyler.
How many of Carl Laemmle, Sr.'s relatives were working for Universal as of 1928?

ANS:
70
