Answer:
The electric force between them decreases
Explanation:
The force between two charged particle is given by :
Where
r is the distance between charges
If the distance between the charges is increased, the electric force gets decreased as there is an inverse relation between force and distance.
Hence, the correct option is (c) "The electric force between them decreases"
Answer: Relative humidity
Explanation:
Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor has higher relative humidity in cool air than in warm air. A related parameter to that regard is that of dew point.
Answer:
<h2>9 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 3 × 3
We have the final answer as
<h3>9 kg.m/s</h3>
Hope this helps you
The relationship between hypotheses, laws and theories is that a law is used to explain hypothesis and theories.
<h3>What is a law, a theory and hypothesis?</h3>
A hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further investigation or experimentation.
A theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.
A law is a statement whose sequence or relationship of phenomena is invariable under certain conditions.
This suggests that a law can be used to explain a theory and hypothesis.
