Answer: It encourages scientists to give convincing evidence for the results
Answer:
First answer.
Explanation:
There may be a 5N force, but if the frictional force also equals 5N, than they cancel eachother out, resulting in the brick still staying still, as it is resting on a (perfectly) level surface, but any amount of force would make the brick move.
Answer:
1/ K times
Explanation:
The capacitance of a parallel plate capacitor is given by

Where, A be the area of plates and d be the distance between the plates.
When a dielectric is inserted between the plates, the new capacitance is

The charge remains same.
As we know that
q = C V
The capacitance becomes KC so, to keep the charge remains same the potential difference should be 1 / K times.
V' = V / K
Explanation:
The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).
