Q. An object is placed 12.0 cm in front of a converging lens of focal length 5cm. A concave mirror with radius of curvature 20.00 cm is located 30.00 cm in back of the lens. (Refer to attached picture)
1.) At what distance from the lens does first image (from the lens) form?2.) What is the magnification of first image?3.) What is the object distance to be used to determine the image formed by mirror?4.) What is the distance from the mirror to the image formed by mirror?5.) What is the magnification of the mirror image compared to the original object seen by lens?6.) Is the image formed by the mirror real or virtual?7.) Find out the location and magnification of the final image
A 2kg ball traveling to the right with a speed of 4 m/s collides with a 4 kg ball traveling to the left with a speed of 2 m/s. The total momentum of the two balls after the collision is what.
A 76 g, 40-{rm cm}-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 10 g ball of clay travelling horizontally at 2.70 m/s hits and sticks to the very bottom tip of the rod. To what maximum angle, measured fro..
A car is moving down a street at 53 km/h. A child all of a sudden runs into the street. If it takes the driver 0.74s to react and apply the brakes, how many meters will the car have moved before it begins to slow down?
At launch, the space shuttle's engines offer a thrust of 29 x 10^6N, and it accelerates upward at 1.75 m/s^2. What is the shuttle's mass.
In what direction should the plane head in order to fly.
Get the expression for how moving clocks run slowly when seen by observers at rest.
What is the magnitude of the force on the bead. find the charge of the particle.
A 13g bullet traveling 221 m/s penetrates a 2 kg block of wood and emerges cleanly at 160 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
What would be the final temperature of 100g of 16°C water when 107 g of 40°C iron nails are submerged in it? (The specific heat of iron is 0.12 cal/g °C. Here you must equate the heat gained by the water to the heat lost by the nails.)
Suppose you see two main-sequence stars of the same spectral type. Star 1 is dimmer in apparent brightness than Star 2 by a factor of 100. What can you conclude? (Overlook any effects that might be caused by interstellar dust and gas.)
Differences in analysing a roller coaster system as particle and rigid body, such as the assumption(s) made when treating the roller coaster as particle, parameters involved in kinematic and kinetic analysis.
A plate carries a charge of -3.7 C, while a rod carries a charge of +1.9 C. How many electrons should be transferred from the plate to the rod, so that both objects have the same charge.
