physical property is a characteristics of a pure substance that can be observed without changing the substance into someone else.
Answer with Explanation:
The force of attraction between 2 charges of magnitude separated by a distance 'r' is given by
where
is a constant known as permitivity of free space
Applying the given values in the above relation we get
(2) impulse is a vector quantity. Energy has no direction, nor does power. Work is a dot product of vector quantities, which makes it a scalar.
Answer:
option A
Explanation:
The correct answer is option A
Reproducible experiment is a specific experimentally produced value is said to be reproducible when there is a fair degree of consistency between measurements or observations done by different people at different locations on duplicate specimens — that is, if the test value is determined to be of great accuracy.
hence, a scientific hypothesis can be disproved with one reproducible experiment.
