Q1. If the distance between two slits is 0.031 mm and the distance to a screen is 2.50 m, find the spacing between the first- and second-order bright fringes for yellow light of 500 nm wavelength.
Q2. A student makes a simple generator by using a single square loop cm on each side. The loop is then rotated at a frequency of Hz in a magnetic field of T.
A particle oscillates with S.H.M. The maximum displacement from its mean position is 0.5 meter and frequency of motion is 10 Hz. at time t=0, particle is located at 0.15 meter and has the velocity of 24.0 m/s towards the negative x-axis.
Find the closest distance an alpha particle of kinetic energy 5.0MeV can approach a bare gold nucleus, What is its kinetic energy in eV when it is expelled to infinity
The rear axle of a truck is 2.5 m long. If the truck is moving at 28 m/s, what emf is induced between the ends of the axle
During the launch from a board, a diver's angular speed about her center of mass changes from zero to 4.50 rad/s in 220 ms. FIND the magnitudes of her average angular acceleration
Assuming no heat loss to the surrounding environment, determine the minimum duration of time necessary for a 100 W aquarium tank heater to raise the temperature of 20.0 gallons of water by a difference of 10.0°C.
A cosmic ray proton streaks through the lab with velocity 0.80c at an angle of 55° with the +x direction (in the xy plane of the lab). Compute the magnitude and direction of the proton's velocity
What is a gyroscope? Discuess the role of angular momentum in operation of a gyrosope. Provide examples of pratical applications of gyryscopes
A 79.2 kg airplane pilot pulls out of a dive by following, at a constant speed of 191 km/h, the arc of a circle whose radius is 321m.
A large block 19.0 cm wide, 20.0 cm long, and 24.00 cm high of mass 4.55 kg. This block is passing through air (density ?air = 1.43 kg/m3). Calculate the terminal velocity of the block
The local acceleration of gravity is 9.813 m/s 2 , and the atmospheric pressure is 101.57 kPa. a) What is the force (in Nt) exerted on the gas by the piston, the weight and the atmosphere combined
Because the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it should be released above the top of the loop-the-loop height.
A spacecraft is traveling with a velocity of v0x = 5675 m/salong the +x direction. Two engines are turned on for a time of 847 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.25 m/s2,while the other gives it an acc..
