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: 3
Explanation:
Physics has 5 laws. But the 3 laws of Newton has been clubbed together under one Law. Therefore there are 3 Newtons laws of Physics. They are ::
1. Newtons Laws of Motion
a. First Law of Motion
b. Second Law of Motion
C. Third Law of Motion
2. Newtons Law of Cooling
3. Newtons Law of Gravitation.
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: 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.
Correct Answer: Cylindrical lens
Explanation:
Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea is irregularly shaped or sometimes because of the curvature of the lens inside the eye.
