Q. Coherent light with wavelength 590 mm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 m from the slits. The first-order bright fringe is a distance of 4.84 mm from the center of central bright fringe. For what wavelength of light will the first-order dark fringe be observed at this similar point on the screen? For what wavelength of light would the first-order dark fringe be observed at this same point on the screen?
if ellis is on earth, mario is on mars and monique is on the moon. they all have a mass of 50kg. they all jump off a trampoline. who will jump the highest. find what is the Tension T2 in the left.
How to find the length
A 2 kg object is attached to a spring and placed on a horizontal, smooth surface. A horizontal force of 20.0 N is needed to hold the object at rest when it is pulled 0.200 m from its equilibrium position.
A planet's moon travels in an approximately circular orbit of radius 6.6 x10^7 m with a time of 7 h 9 min. Calculate the mass of the planet from this information.
When a train's velocity is 12{rm{ m/s}} eastward, raindrops that are falling vertically with respect to the earth make traces that are inclined 30.0 ^circ to vertical on windows of the train.
A jeweller working with a heated 44 g gold ring must lower the ring's temperature to make it safe to handle. If the ring is initially at 94 degrees Celsius, what mass of water at 25 degrees Celsius is necessary to lower the ring's temperature to 35 d..
A 1.50 kg block of wood sits at the edge of a table, 0.782m above the floor. A 0.0105 kg bullet moving horizontally with a speed of 770m/s embeds itself within the block. What horizontal distance does the block cover before hitting the ground.
The Mini Cooper is rated at the maximum power of 115. hp (1 hp=746 W), when moving at 80km/h. Suppose that the net force accelerating the car is constant.
The electric field lines on the left have twice the separation of those on the right. If the magnitude of field at point-A is 60 V/m, what is the magnitude of the field at point-B.
The bullet passes right through and emerges on the other side with a speed of 100 m/s, and the saxophone is given a speed of 4.8 m/s.
A person carries a long pole of mass 20 kg and length 3.4 m at the angle of 60 degrees. Find the magnitude of the torque on the pole due to gravity.
what was the initial speed given to the rock. A light plane is headed due south with the speed of 154 km/h relative to still air. After 1.06 hour, the pilot notices that they have covered only 127km and their direction is not south but southeast (4..
