To determine and verify experimentally the law for total resistance (RT) of a series-parallel combination circuit.\n2. To verify that the voltage across each leg in a parallel circuit is the same as the voltage across the parallel network.
A thin spherical shell of mass M = 3.00 [kg] and radius R = 1.50 [m] compresses a spring (k = 500. [N/m]) by 0.400 [m]. After releasing the shell from rest, it rolls without slipping along the floor and up a surface inclined at an angle θ = 30.0◦, as shown in the figure. What is the angular speed of the shell when it reaches a distance L = 2.00 [m] from the base of the incline? (I = 2/3mr^2)
How far would a horse that rides at 7.7 m/s travel in 8.2 minutes?
A motorist, traveling at the 120km/hr sees a broken down truck at the middle of the road and immediately applies his brake and comes to stop with uniform retardation in 20 secs. What distance does the car travel after the brakes were applied?
If 3/4 of a rope is 150 mm how long is the entire rope
THE EFFICIENCY OF A CERTAIN MACHINE IS 80 WHAT WORK IS REQUIRED TO RAISE A BOX OF MASS 200KG A DISTANCE OF 6M USE G = 10M/S²
the loaded roller coaster has a mass of 2500 kg. the starting point of the run is 22m above point A; the run from B to C is 120m long; the run from C to D is 100m. at D, brakes are applied, bringing the coaster to a halt 15m further along a E. if the friction from B to D is 0, find
(a) the potential energy of the roller coaster at the starting point
(b) KE of the roller coaster at C
(c) the speed of the roller coaster at D; the average braking force applied between D and E

a) The temperature of 200 g of water increases from 20°C to 50°C in 10 minutes. Calculate:
i. the amount of heat gained by the water.
ii. the average rate at which the water is gaining heat.
(Specific heat capacity of water = 4200 J kg-1 OC-1)
b) Determine the amount of heat that must be removed from 1 kg of water at 40°C to convert it to ice at -5°C.
