Light of wavelength 730nm falls on two slits and produces an interference pattern in which the fourth-order fringe is 53mm from the central fringe on a screen 3.0m away.
Part A What is the separation of the two slits?
plan a free-body diagram of the wire and bird system. How much tension does the bird produce in the wire? Ignore the weight of the wire.what is the rotational inertia of the wheel.
A recent tomb has been unearthed in Egypt that shows the set of wall paintings and hieroglyphics of stars falling to and rising above the horizon over the course of the year (these stars served as sentinels for the pharaoh's passage through the un..
A dolphin leaps out of the water at the angle of 46° above the horizontal. The horizontal component of the dolphin's velocity is 9.40 m/s. Find out the magnitude of the vertical component of velocity.
A 0.170 kg tumour is being irradiated by a radioactive source. Each decay of the radioactive source produces a particle with an energy of 0.450 MeV. find the activity of the radioactive source
A ski gondola is connected to the top of a hill by a steel cable of length 680 m and diameter 1.5cm. As gondola comes to the end of its run, it bumps into the terminal and sends a wave pulse along cable. It is observed that it took 14 s for the p..

It then increases it's speed at the rate of 1.55 m/s2. Find out the magnitude of acceleration under these new conditions. Answer in units m/s2.
The horizontal component Fx is shown by the histogram below as function of position along x-axis. There is also a kinetic frictional force of 0.50 N between mass and surface.
Two round rods, one steel and the other copper, are joined end to end. Each rod is 0.795m long and 1.85cm in diameter. The combination is subjected to a tensile force with magnitude 3950N.
