Answer: The correct answer is "inertia".
Explanation:
Inertia: It is the state of the object which resists any change in it.
Newton's first law is also called "Law of inertia".
If the object is travelling at constant velocity then it will remain travel at the constant velocity or if it is at rest then it will remain in resting position provided that it is acted upon by an external force.
If the external force is applied to an object then, the state of the object can be changed. Otherwise, it will remain in its state.
Therefore, the tendency for an object i motion to remain in motion is called inertia.
B. the low pressure at the bottom.
C. the low pressure in the mountain.
D. the high pressure in the mountains.
Answer: The correct answer is the low pressure in the mountains
Explanation:
The air pressure is lower in the mountains. As we travel up into the mountains, the air inside our ears takes some time to adjust the pressure change.
This unequal pressure causes discomfort in ears while ascending and descending on the mountain. The condition of discomfort in ear is caused by the pressure difference between the outside and inside the eardrum.
Therefore, as we travel up to into the mountains, we notice discomfort in our ears. This is due to the low pressure in the mountain.
b. radiation.
c. conduction.
d. density.
Heattransfer within a fluid takes place by convectioncurrents. The correct option is a.
Convection currents are principally responsible for heat transmission within a fluid. Heat is transferred through the fluid's own movement through convection.
Heat causes a fluid's particles to gain energy and lose density, which causes them to rise. Heat energy is carried upward by the heated fluid.
A cycle of circulationresults from the movement of colder fluid from the surroundings into its place in the interim.
Through this mechanism, heat can be moved from hotter to cooler areas of the fluid. Convectioncurrents are frequently seen in fluids like air and liquids, and they're important for both engineering and a variety of natural occurrences.
Thus, the correct option is a.

Answer:
the answer is A. convection currents
Explanation:Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology. Convection is different from conduction, which is a transfer of heat between substances in direct contact with each other.

Explanation:
2) C would need the least effort, because the longer the effort distance, the least the effort applied.
B. a wire connected in a complete loop
C. a source of electrical energy
Answer: The correct answer is an electrical insulator.
Explanation:
Insulator : It is a material which resists the flow of electrons. It has high resistance in comparison to the conductor.
Conductor: It is a material which allows the flow of electrons. It has low resistance in comparison to the conductor.
Battery is a source of electrical energy. It forces the electrons to flow. The rate of flow of electrons constitutes the current.
In the given problem, an electrical insulator is not needed for a charge to flow through a conducting wire.
To design the circuit and to make a current flow in the circuit, a battery, a wire connected in a complete loop and a source of electrical energy are needed.
Therefore, the correct option is (C).
