(e) The positively charged part of the atom possesses most of the mass in ..........(Rutherford's model/both the models.)
A Sphere on a Horizontal Surface starts from Rest. If the Force is applied facing to the Right at the Top furthest Point of the Sphere from the Horizontal Surface, the Sphere will start experiencing Roll and Slip at the same time. In which directi..
A uniform plank of length 4.30 m and weight 226 N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 437 N walk on overhanging part of the plank be..
A projectile is projected from the origin with a velocity of 15.0 m/s at an angle of 30.0 degrees above the horizontal. What is the location of the projectile 2.00 seconds later?
In a single slit diffraction experiment, the angular width of the central maximum is 0.16 degrees. The width of the slit is then doubled as is the distance to the screen. What is the resulting angular width of the central maximum?
A car speeds past a stationary police officer while travelling 115km/h. The officer immediately begins pursuit at a constant acceleration of 10.20 km/h/s (note the mixed units), just as the driver passes the officer.
It is cruising at a constant speed of 245 km/hr at 11,000 m. The coefficient of static friction between the airplane seat and a person is 0.28.
