I think so it ans wold be d.because if the source approaches the observer more and more wavefront will pass and it get squeezed.so wavelength decreases and frequency increases.
Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity. Good luck on your assignment and have a great day! :D
The answer is 30 ... same as the Atomic number.
Answer: C both A and B
Explanation:
Transmission : This simply implies the difference in rotation speed between the input shaft and output shaft. Note that higher gear ratios are used to transfer more torque, of which lower ratios trade torque is in favor of speed. Technician A was right
The primary functions of the transmission includes transmitting of the engines crankshaft into a more usable rotational speed and to multiply the torque of the engine's output. Hence,
Technician B was also right.
