Answer:
continually change by the same amount each second
Explanation:
We all are aware with the fact that a car speeds is increased when we put our feet on the accelerator. The rate at which the particle's velocity change with time is called its acceleration. If the particle's velocity changes with constant rate, then its rate is called the constant acceleration.
Since the basic units are meter and seconds. And the SI unit of velocity is 
and acceleration's SI unit is 
For example if the velocity is change from 2 to 4 m/s in 1 sec its acceleration is 
and again its velocity is change with 4 m/s to 6 m/s will again give constant acceleration in 1 s is .
The correct answer is option (c) i.e. Energy will be converted into another form.

During a chemical reaction, energy remains unchanged, It just gets converted into another form and doesn’t increases or decreases. Excess energy is released in the form of heat, light during a chemical reaction and thus, proving the law of conservation of energy which says, energy can neither be created nor destroyed. It just gets converted from one form to another form. </span>
An increase in the entropy of a system can be described as an increase in the total amount of disorder in a system.
Entropy
Entropy is a measurable physical characteristic and a scientific notion that is frequently connected to a condition of disorder, unpredictability, or uncertainty. From classical thermodynamics, where it was originally recognized, through the microscopic description of nature in statistical physics, to the fundamentals of information theory, the phrase and concept are utilized in a variety of disciplines. It has numerous applications in physics and chemistry, biological systems and how they relate to life, cosmology, economics, sociology, weather science, and information systems, especially the exchange of information.

D) both can show interference effects
The highest frequency (f) at which the source can operate is given as:
f = 55.133Hz.
<h3>What are sinusoidal waves?</h3>
The most realistic representation of how many objects in nature change state is a sine wave or sinusoidal wave.
A sine wave depicts how the intensity of a variable varies over time.
<h3>What is the calculation justifying the above result?</h3>
P = (1/2) μω²A²v
300W = 1/2 (4 X 10⁻²kg/m) ω₂ (0.05m)²v
Thus the wave speed is:
v = √(T/μ)
= √[(100N)/(4 X 10⁻²kg/m)
= 50m/s
300W = 1/2(4 X 10⁻²kg/m) ω²(0.05m)² (50m/s)
⇒ ω = 346.41 1/s
ω = 346.41 1/s
= 2πf
⇒ f = 55.133Hz
