Some of the most energetic events in the universe occur when stars explode in an incredible release of energy known as a supernova. although every supernova is characterized by a sudden, intense brightening, the differences in types of progenitor stars and the mechanisms of detonation produce two distinct supernova types: type i and type ii. rank the following steps that lead to a type i supernova event in order of when they occur from first to last. rank the steps of the supernova mechanism from first to last.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
