Ineed like right ! 1. even though numerous safety devices are designed into nuclear power plants, the benefits must be weighed against potential hazard risk of accident waste disposal all of the above 2. the current major disadvantage of using solar power on a large scale is safety reliability economics lack of consistent sunlight. 3. two advantages of hydroelectric power are no ecological impact nonpolluting relatively low cost can be developed anywhere 4. the nucleus contains protons and neutrons protons and electrons neutrons and electrons protons and isotopes

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.

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

Frequency of electromagnetic waves that a radio station is assigned is called
