Two guns situated at the top of a hill of height 10m, fire one shot each with the same speed m/s at some interval of time. One gun fires horizontally and other fires upwards at an angle of 60degrees with the horizontal. The shots collide in air at a point P.
(1) Find the time interval between the firing..
(2) The co-ordinates of the point P.
Take origin of the coordinate system at the foot of the hill right below the muzzle and the trajectories in the x-y plane.
The electric field of a sinusoidal electromagnetic wave obeys the equation E=?(375V/m)sin[(5.97×1015rad/s)t+(1.99×107rad/m)x]. What is the amplitude of the electric field of this wave
Assume that the value of n in a radioactive transition in hydrogen changes only with unity, as is suggested by the correspondence principle. Estimate for what range of values of n the photon that is emitted will have wavelengths in the visible range ..
The figure shows tow disks, A and B, commented together, that are rotating with angular acceleration, α. The radius of the small disk B is 2/3 the radius of the larger disk. Compute the h ratio of the tangential velocity of a point on the rim of disk..
A straight conductor carrying a current of 19 A splits into identical semicircular arcs of radius 13.3 m. The positive direction is out of the screen. What is the magnetic field at the center of the resulting circular configuration?
A string 40.0 cm long and fixed at both ends of a musicalinstrument oscillates in its n= 1 mode. The speed of waves onthe string is 233m/s, and the speed of sound in air is 348m/s.
A 0.04 kilogram lead bullet traveling 209 meter per second strikes an armor plate and comes to a stop. find what is its temperature change
in the relativistic heavy ion collider in brookhaven ny physicists are attempting to recreate the conditions of the big
Sound is considered an electromagnetic wave. The electric field in an electromagnetic wave is parallel to the magnetic field. An accelerating reference frame is considered as an inertial reference frame. In the photoelectric effect, light acts like a..
