Answer:
d. remains same
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
If both the mass of the body and the force acting on it are doubled, then acceleration remains the same.
Given the following data;
Mass = 2Mass
Force = 2Force
Substituting into the formula, we have;
Such system is called RADAR (<span>RAdio </span>Detection<span> And Ranging).
The Radar emits radio waves, that are reflected back by the object. Since the speed of the radio waves is known (their speed is equal to the speed of light), by measuring the time the waves take to come back to the source it is possible to infer the distance they covered, and so the distance of the object.</span>
