- 4. Which liquid is the most viscous?
Options- A. Water
- B. Diesel
- C. Milk
- D. Oil Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO, IT Trainer
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.
- 5. How many laws of physics are there?
Options- A. 5
- B. 4
- C. 3
- D. 2 Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO, Database Administrator, IT Trainer
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.
- 6. "Light years" is the unit of _____?
Options- A. Acceleration
- B. Distance
- C. Light Intensity
- D. Weight Also asked in: AIEEE, Bank Exams, CAT, GATE, Bank Clerk, Bank PO
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.
