In Maglev trains, magnetic force exist between objects that are not in contact but can interact at a distance.Hence, the statement is true.
What is a force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

The given scenario is the best example of how the sun is the main source of energy for the water cycle.
What is water cycle?Water cycle is an atmospheric phenomenon in which the atmosphere and hydrosphere are involved. This process balance the amount of water in land and the atmosphere.
The heat energy radiated from sun make water sources warm up and water evaporates to the atmosphere. The water vapor in the atmosphere condenses to form liquid droplets and fall as rain.
Thus, solar energy is the main source to balance water content in atmosphere and land by water cycle and to maintain a living condition. Hence, option c is correct.

Why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis?
Answer:
Radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis because radio telescopes are devices used to capture radio light waves, bring it to focus, overdraw it and use the data for processing and analysis. These radio light waves, that are raw analog signals, are converted into digital signals to create and distinguish delicate details in the universe.
