Question: Starting from rest, a boat increases its speed to 4.27m/s with constant acceleration. If it takes the boat 4.57s to reach this speed (4.27m/s ), how far has it traveled? Average speed is 2.14 m/s.
Express your knowledge to solve the above question to find how far has it traveled?
In Rutherford’sfamous scattering experiment that led to the planetary model of theatom, alpha particles (having a charge of + 2e and a mass of 6.64 x10-27 kg) were fired toward a gold nucleus with charge of + 79e. Thealpha particle, initially very..
