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: Syrup
Explanation:
The 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".
Here in the given options, syrup has the highest viscosity.
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: 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.
Correct Answer: chemical potential energy
Explanation:
Gasoline is a colorless petroleum-derived flammable liquid that is used primarily as a fuel in spark-ignited internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. It is also called as Petrol. It has chemical potential energy, in combustion it is turned into light, sound, heat and kinetic energy.
Correct Answer: Collide
