Science is concerned mainly with the A. Natural world, I believe.
Answer:
C. The given value is a statistic for the yearyear because the data collected represent a samplesample.
Explanation:
A parameter is a numerical measurement of a population while a statistic is a numerical measurement of a sample. Statistics use assumptions to represent relations among variables and parameters should meet requirements and present more objective data. In this case, the voltage value found is the mean of a 34 days sample and, therefore, the given value is a statistic of the daily voltage for the year.
Answer:
- Solar nebula
- Planetesimal
- Heavy bombardment
- Accretion
- Solar wind
- Condensation
- Frost line
- Radiometric dating
Explanation:
Solar nebula is a gaseous cloud and it have been considered that when it condensed, Sun and other planets are formed.
Planetesimal term is used for an object which is formed from rock, dust and some other materials.
When growth occurs due to gradual accumulation of layers then it is called Accretion.
A stream of charged particles (electrons and protons) having extreme energy and flowing outward from the Sun at speeds approximately 900 km/s and at a temperature of 1 million degrees is termed as Solar wind.
Radiometric dating is the name of technique that is used to calculate the age of the materials such as rocks or carbon.
Speed of light= wavelenght * frequency
Frequency = (3x10^8)/(1 x 10^-4)
= 3 x 10^+12
