1. Three capacitors with individual capacitances of 2 μF, 5 μF, and 10 μF
respectively are connected in series with a 12V battery. What are the total
capacitance and total charge in the network?
2. Same capacitors in number 1 connected in a parallel. If the combined
charge in the network is 50 μC, what are the total voltage and total
capacitance in the network?
The radio tuning capacitor consists of 26 plates of area 24 cm2. The distance between plates when set for maximum capacitance is 2mm. Assuming that the area of projection at maximum capacity is equal to the area of the plates, find the maximum capacity of this condenser.
In raising a 5000-N piano with a pulley system, the workers note that for every 2m or rope pulled down, the piano rise 0.4m.
A. ideally, how much force is required to lift the piano?
B. if the workers actually pull with 2500N of force to lift the piano, what is the efficiency of the pulley system?
Light of wavelenght 500nm is directed normally to a double slit of 1.5mm. If the fringes is observed at a distance of 2m, what is the fringe separation? How many fringes can be observed in 1cm?
Light of wavelength 500nm is directed normally to double-slit of 1.5mm. If the fringes is observed at a distance of 2m, what is the finge separation? How many fringes can be observed in 1m?
Friges in an interference pattern is observed to be 2mm apart. if the silt separation is 1mm and the wavelenght of light is 400mm. What is the distance of the screen where the observation was made?
on top of a spiral spring of force constant 509N is placed placed in mass of 5x10raise to power 3 . If the spring is Compressed down ward by alength of 0.02m and then release Calculate the height to which the mass projected
A box-shaped metal can has dimensions 7 in. by 12 in. by 3 in. high. All of the air inside the can is removed with a vacuum pump. Assuming normal atmospheric pressure outside the can, find the total force (in lb) on one of the 7-by-3 in. sides. (Enter the magnitude.)
A bus moves 15 km east and turns 45 ᵒ N of E for another 5 km before coming to stop. Find the magnitude and direction of the resultant displacement of the bus.
A boy on a 2.0 kg skateboard initially at rest tosses an 8.0 kg jug of water in the forward direction. If the jug has a speed of 3.0 m/s relative to the ground and the boy and skateboard move in the opposite direction at 0.60 m/s, find the boy’s mass.
