An object is so = 2 m from the front side of a converging lens with focal length f1 = 1 m. A second converging lens with focal length f2 = 2 m is placed a distance d = 1 m from the first on the opposite side from the object. Draw a ray diagram of the situation. What is the distance of the final image from the second lens? What is the magnification of the lens system? The object is now moved inward until it is at so = 1 m from the front of the first lens. Draw a ray diagram of the new situation. Where is the final image now? What is the new magnification?
A 2.6k and a 1.8k resistor are connected in parallel and this combination is connected in series with a 1.8k resistor. If each resistor is rated at 1/2W, what is the maximum voltage that can be applied across the whole network.
Two sinusoidal waves of the same period, with amplitudes of 5.5 and 7.5 mm, travel in the same direction along a stretched string; they produce a resultant wave with an amplitude of 12.760 mm. The phase constant of the 5.5 mm wave is 0. What is th..
A stone is dropped into a river from a bridge at a height h above the water. Another stone is thrown vertically down at a time t after the first is dropped. Both stones strike the water at the same time. What is the initial speed of the second sto..
The magnitude of a uniform electric field between the two plates is about 2 × 105 N/C. If the distance between these plates is 0.1 cm
The acceleration of gravity is 9.81 m/s^2. Assuming that air resistance is simply a constant 96 N force on the person during the fall, identify the person's velocity just before hitting the net. Answer in units of m/s.
A copper block is removed from a 300^0 C oven and dropped into 1 L of water at 20.0^0 C. The water quickly reaches 25.5^0 C and after that remains at that temperature. What is the mass of copper block.
if the box is moving at a constant speed of 0.35m/s and the coefficient of kinetic friction is 0.12. What is the magnitude of F.
Three deer, A, B, and C, are grazing in a field. Deer B located 64 m from dear A at an angle of 53° north of west, What is the distance between deer A and C
A non-uniform bar 5 meters has a center of gravity 1 meters from the heavy end. If it is placed on the edge of a block 1 meters from the light end and a weight of 1497N is placed at the light end of the bar, it will be balanced. What is the weight..
determine the angle below the horizontal that you must aim your spear gun in order to catch dinner. Suppose the spear gun barrel is 1.70 m above the water surface, the fish is 1.40m below surface, and the spear travels in a straight line all the w..
A pie plate is filled up to the brim with pumpkin pie filling. The pie plate is made of Pyrex and its expansion can be neglected. It is the cylinder with an inside depth of 2.10 cm and an inside diameter of 30 cm.
