An electromagnetic wave of intensity 180 W/m2 is incident normally on a rectangular card with sides of 20 cm and 32 cm that reflects the entire radiation incident on it. Discover the force exerted by the electromagnetic wave on the card if the radiat..
Liquid nitrogen has a boiling point of 77.3 K and a latent heat of vaporization of 2.01 105 J/kg. How many kilograms of nitrogen are boiled away in a period of 5.00 h
A body is moving with velocity of 8m/s. After 5 Seconds the velocity of the body becomes 18m/s. Find the acceleration of the body
A 512-turn circular-loop coil with a diam- eter of 17.4 cm is initially aligned so that its plane is perpendicular to the Earth’s mag- netic field. In 2.46 ms the coil is rotated 90.0? so that its plane is parallel to the Earth’s magnetic field. An a..
(a) A hydrogen atom has its electron in the n = 4 level. The radius of the electron's orbit in the Bohr model is 0.847 nm. Find the de Broglie wavelength of the electron under these circumstances.
After fixing a flat tire on a bicycle you give the wheel a spin. If its initial angular speed was7.01 rad/s and it rotated 15.0 revolutions before coming to rest, what was its average angular acceleration? (Consider speeding up positive and slowing d..
A 0.73-kg magnetic target is suspended on a string. A 0.025-kgmagnetic dart shot horizontally, strikes the target head-on. The dart and the target together acting like a pendulum, swing 12.0 cm above the initial level before instantaneously coming to..
Engineers can determine properties of a structure that is modeled as damped spring oscillator-such as a bridge-by applying a driving force to it, What is the oscillator\'s damping constant? (kg/s)
