The statement given below signifies which of the law/principle given in the options. “An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.”
First law of motion
Newton's first law of motion states that a body stays at rest or keeps moving uniformly in a straight line unless an external (unbalanced) force acts on it. It is also called the law of inertia.
The given statement says exactly this, so it describes the first law.
The second law relates force to the rate of change of momentum (F = ma), the third law says every action has an equal and opposite reaction, and Bernoulli's principle concerns pressure and speed in a moving fluid. None of these matches the statement.
Hence, First law of motion.

In a desert, a beetle's motion sends fast longitudinal pulses, vL = 150 ms-1, and slower transverse pulses, vS = 50 ms-1, along the sand's surface. The sand scorpion has eight legs; spread roughly in a circle of 5 cm diameter, intercepts the faster longitudinal pulses 4.0 ms earlier than the slower transverse pulse. The pray is located at a distance of:
