Answer:
Natural science is concerned with the description, prediction, and understanding of natural phenomena based on empirical evidence from observation and experimentation. It can be divided into two main branches: life science (or biological science) and physical science.
Explanation:
The mean height for the grass used as a control is equal to the total number of the data came from the control grass divided by the number of control grass in the experiment. The mean height means the average height of the grass.
Answer:
When a capacitor is fully charged, no current flows in the circuit. This is because the potential difference across the capacitor is equal to the voltage source. (i.e), the charging current drops to zero, such that capacitor voltage = source voltage.
Explanation:
Hope this helps
Answer:
The Work Done is
Explanation:
Since , the equipment is pulled in horizontal horizontal plane.
Therefore, its normal reaction must be equal to its weight.
So, Normal reaction,
We know, frictional force ,
(Where N is Normal reaction and is coefficient of kinetic friction )
Therefore,
We know ,
( Here D is distance covered by the force)
Putting, D=1000 m.
We get , Work Done
