- Question
Which of these liquids has the highest viscosity?
Options- A. Milk
- B. Syrup
- C. Pineapple juice
- D. Water
- Correct Answer
- Syrup
ExplanationThe viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness".

Correct Answer: Power
Explanation:
The Rate of doing work or rate of transfer of energy is called Power.
Correct Answer: Acceleration
Explanation:
Centrifugal force is the fictitious force that pulls out from the center on the body we feel while moving in the circular path. It increases with the rate of rotation of the axis i.e, acceleration of the body.
Correct Answer: Flow of fluids
Explanation:
A rotameter is a flow meter that measures volumetric flow of liquids and gases.
Correct Answer: Velocity
Explanation:
Speed in a given direction is called Velocity.
Correct Answer: 10^16 mts
Explanation:
Light year is the unit of to express astronomical distances, that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.
Approximately, 1 light year = 10^16 mts.
Correct Answer: Gravitational force is the force that binds everything at the surface of the earth It holds at what distance from the earth is gravity zero
Correct Answer: Helium
Correct Answer: Magnetic striping is evidence of seafloor spreading
Correct Answer: Anemometer
Correct Answer: Book
Explanation:
The objects through which light cannot pass are called as Opaque objects. Some objects allow some light to pass through them and are called as Translucent objects. The objects which allow all the light to pass through them are called as Transparent objects.
Here in the given options Book is an example of opaque object as it does not allow light to pass through it. Water is transparent object and notebook paper and sun glasses are examples of translucent objects.
