Correct Answer: Oil
Explanation:
Here Oil is the most viscous liquid.
The liquid with the most intermolecular force is high viscous. viscosity is how smoothly a liquid flows and how hardly the liquid flows it is highly viscous.
Correct Answer: Pascal's Law
Correct Answer: momentum
Correct Answer: Potential energy
Explanation:
An object at rest may have Potential energy.
Correct Answer: Both B & C
Explanation:
Distance between two Consecutive Crests or two Consecutive Troughs is called Wavelength. But the distance between crest and adjacent trough is half the wavelength.
That is the distance between adjacent crest and trough is called Half the wavelength.
Correct Answer: Distance
Explanation:
A Light-year is a distance that light travels in the vacuum in one Julian year (365.25 days).
The light-year is a unit of length used to express astronomical distances. It is about 9.5 trillion kilometers or 5.9 trillion miles.
Correct Answer: 32
Explanation:
Correct Answer: Argon, copper, silver
Correct Answer: fossils
Explanation:
Radiocarbon dating also referred to as carbon dating or carbon-14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
Correct Answer: Velocity
Explanation:
The rate of change of velocity is called as Acceleration.
