Answer:
gathered by using measurement tools and math
Explanation:
Quantitative data is often gathered by using measurement tools and math.
A quantitative data set is assigned values and numbers in order to solve a problem or for the purpose of a study.
- Each data set has a unique numerical value and can be counted.
- Qualitative data set does not use numerals and numbers.
- It engages the senses to make some scientific deductions.
- Examples are measurement of volume, distance, length, time, number of moles e.t.c
- Qualitative data sets include taste, smell, color e.t.c
Answer:
Silage can be made by one or more of the following methods: placing cut green vegetation in a silo or pit; piling the vegetation in a large heap and compressing it down so as to purge as much oxygen as possible, then covering it with a plastic sheet; or by wrapping large round bales tightly in plastic film.
Explanation:
Answer:
Originally : Level = log I / I0
Currently: Level = 10 log I / I0
Level = 10 log 600 = 10 * 2.78 = 27.8
Note the term 1 bel = 10 decibels
Answer:
a) 
b) 
c) 
d) 
e) 
Explanation:
At that energies, the speed of proton is in the relativistic theory field, so we need to use the relativistic kinetic energy equation.
(1)
Here β = v/c, when v is the speed of the particle and c is the speed of light in vacuum.
Let's solve (1) for β.
We can write the mass of a proton in MeV/c².
Now we can calculate the speed in each stage.
a) Cockcroft-Walton (750 keV)
b) Linac (400 MeV)
c) Booster (8 GeV)
d) Main ring or injector (150 Gev)
e) Tevatron (1 TeV)
Have a nice day!
Answer:
Displacement is the shortest distance travelled from the initial point to the final point. After half revolution the displacement is the length of the diameter which is equal to 2r. Hence the displacement is 2r.
