Silver is a very good conductor, this means its resistivity is very low (from table, we can check the precise value, which is
).
Pure water, instead, is a very bad conductor, this means its resistivity is very high, of order of
(
). Even without knowing the precise value of the pure water resistivity, we can estimate the ratio between the pure water resistivity and the silver resistivity by comparing the two orders of magnitude:
Therefore, we can say that the correct answer is
Answer:
Explanation:
A physical quantity which can be completely described by the magnitude and direction both are called vector quantities. For example, displacement, velocity, etc.
A physical quantity which can be completely explained by the magnitude only is called scalar quantity. For example, mass, time, etc.
Carbon is one of the main building blocks of life. This is what carbon dating is so effective, because scientists are able to tell the approximate age of something that was once alive given how much carbon is still in the animal.

calar quantity, length of path. displacement: vector quanity, "as the crow flies" difference between start and finish regardless of path taken. Term.
Explanation:
Answer:
Distance = 13.9 meters
Explanation:
Given the following data;
Maximum speed = 150 km/hr to meters per seconds = 150 * 1000/3600 = 41.67 m/s
Decelerating speed = 3m/s
To find the distance travelled with this speed;
Distance = maximum speed/decelerating speed
Distance = 41.67/3
Distance = 13.9 meters
Therefore, the bus would travel a distance of 13.9 meters before stopping.
