- Why is it useful to define radius of gyration? Radius of gyration is defined as the distance from the axis of rotation to a point where the total mass of the body is supposed to be concen... 2
- In a Young's double slit experiment, light of 500 nm is used to produce an interference pattern. β_(0 )= λ/d = 500 x 10⁻⁹/5 x 10⁻⁵ = 10^(-2 )Radian = 0.57º 2
- Take weights of five of your friends. Find out what their weights will be on the moon and the Mars. Take weights of five of your friend find out what their weights will be on the moon and the mars Let the weights of my friends a,b,c,d,e be... 3
- e. If the value of g suddenly becomes twice its value, it will become two times more difficult to pull a heavy object along the floor. Why? Let the mass of the heavy object be m. Thus, the weight of the object or the pull of the floor on the object is W=mg Now, if g becomes twice... 2
- c. Write the three laws given by Kepler. How did they help Newton to arrive at the inverse square law of gravity? Kepler's first law: The orbit of a planet is an ellipse with the Sun at one of the foci. Kepler's Second law: The line joining the planet an... 2
