Correct Answer: mass being converted to energy when protons and neutrons bind together in a nucleus
Correct Answer: Bicycle
Explanation:
Bicycle is a compound machine in the above given options. A compound machine is a machine that is formed by two or more simple machines.
Correct Answer: Conductors
Correct Answer: Kinetic energy
Explanation:
Every object has two typea of energies. They are ::
Potential energy
Kinetic energy
If the object is in motion, then it has Kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object.
Hence, another name for energy of motion is called Kinetic energy.
Correct Answer: Sunlight
Explanation:
A resource is a source or supply from which a benefit is produced. Resources can be broadly classified upon their availability they are renewable and non renewable resources.
Renewable Resources :: A resource that can be replenished after use are known as Renewable resources.
Examples :: Sunlight, Water, biomass,...
Non renewable Resources :: A resource that, once used, is no longer available are known as Non renewable Resources.
Example :: Coal, fossil fuels, natural gas,...
Sunlight is the both renewable and inexpensive resource from the given options.
Correct Answer: Stope
Explanation:
These are called intrusive igneous rocks because the magma has intruded into pre-exiting rock layers. Types of intrusive igneous rocks are granite and basalt .
A batholith is the largest of the intrusive bodies.
Correct Answer: Cinema
Explanation:
Optical illusion is what that refers to persistence of vision with a principle that multiple images blend into a single image in human mind and what is showed in cinema.
Hence, Persistence of vision is the principle behind cinema.
Correct Answer: Scanning tunneling microscopes
Correct Answer: The Basic Speed Law states that you must never drive faster than is safe for present conditions, regardless of the posted speed limit For example, if you are driving 60 kmph in 45 kmph zone, you are not in safe driving and you just not following the speed law
