Sharpimage always falls on the sensor

Reference no: EM13655225

To focus a camera on objects at different distances, the converginglens is moved toward or away from the image sensor, so a sharpimage always falls on the sensor. A camera with a telephotolens (f = 440 mm) is to befocused on an object located first at a distance of 3.5m and then at 50.0 m. Over whatdistance must the lens be movable?

What is the ratio of the balls final speeds : A ball of mass m = 2.1 kg moving with a speed of v0 = 15.2 m/sstrikes an identical ball which was initially at rest. After thecollision, the incoming ball (ball 1) goes off at q1 = 28°relative to its original direction and the struck ball (ball 2)..

Is it possible for the efficiency of some device : Is it possible for the efficiency of some device or machine to be greater than 1? either give and example where efficiency is greater then 1 or explain why it's not possible.

What is her new rotation frequency in revolutions persecond : A 45 kg figure skater is spinning on the toes of her skates at1.0 rev/s. Her arms are outstretched as far as they willgo. In this orientation, the skater can be modeled as acylindrical torso (40 kg, 20 cm average diameter, 160 cm tall) plustwo rod..

Potential energy of water were converted to electric energy : Water flows over Victoria Falls, which is 128 m high, at an average rate of 1.20 times 106 kg/s. If two thirds the potential energy of this water were converted to electric energy, how much power would be produced by these falls?

Sharpimage always falls on the sensor : To focus a camera on objects at different distances, the converginglens is moved toward or away from the image sensor, so a sharpimage always falls on the sensor.

Loudspeakers in drawing are producing identical soundwaves : The two loudspeakers in the drawing are producing identical soundwaves. The waves spread out and overlap at thepoint P. This situation is analogous to Young’sdouble-slit experiment, except that sound waves are being used.

An electron and a proton are eachaccelerated from rest : An electron and a proton are eachaccelerated from rest in a uniform electric field of 2.0 ×105 V/m. What are their kinetic energies inJoules after they have each traveled a distance of 0.20 m in the electric field?

Net torque on object instatic equilibrium must be zero : The net torque on an object instatic equilibrium must be zero about any axis. If the net force on a system iszero, then the system must be in static equilibrium. A rotating object must beexperiencing a net torque about the rotation axis.

Starts from rest and rolls without slipping for a distance : A wheel of mass 1.24kg and radius 0.44 (I = 0.5mr^2) starts from rest and rolls without slipping for a distance of 1.7m down a 35 degree incline. How fast is it traveling at that point?
