The actual efficiency of an engine can be calculated using the ratio of
the energy of the reservoir compared to the engine intake energy.
Calculate the ideal efficiency and the actual efficiency of a heat engine if
the engine takes in 100 kJ of energy from a source at 810 K and expels
45 kJ to a reservoir at 350 K. Round to the nearest hundredth.
Ideal = 0.26
Actual - 0.45
Actual - 0.65
Ideal - 0.57

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.

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.

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .
