A microscope has a 12.0 x eyepiece and a 59.0 objective lens 20.0 cm apart. Calculate (a) the total magnification, (b) the focal length of each lens, and (c) where the object must be for a normal relaxed eye to see it in focus?
The radius of a proton is 0.9e-15 m; suppose that if the particles touch, the distance between their centers will be twice that. What will be the total kinetic energy of both particles an instant before they touch.
Assume the masses described in the preceding problem are 1kg and 100kg in that order. Compare the accelerations while they are interchanged.
A particular guitar string is supposed to vibrate at 191- Hz, but it is measured to actually vibrate at 210- Hz. By what percent should the tension in string be changed to get the frequency to the correct value.
Two people, one of mass 75kg and the other of mass 60kg, sit in a rowboat of mass 80 kg. With the boat initially at rest, two people, who have been sitting at opposite ends of the boat 3.2 m apart from each other, now exchange seats. How far and i..
What is the kinetic energy
An elevator releases 11200J of gravitational potential energy as descending 4m between floors. How much does elevator weigh.
The collar C is moving downward with an acceleration of 1 m/s2. At the instant shown, it has a speed of 2 m/s which gives links CB and AB an angular velocity ωAB = ωCB = 10 rad/s. Determine the angular accelerations of CB and AB at this instant.
Two objects are charged and their centers are separated by 31.6 cm. Object A is charged to 61 nC and object B is charged to 54 nC. What is the magnitude of the electrostatic force between them.
The rectangular gate CD shown in the figure is 1.8 m wide and 2 long. Assuming the material of the gate to be homogeneous and neglecting friction at the hinge C, determine weight of the gate necessary to keep it shut until the water level rises to..
What is the net entropy change
A plane, diving with constant speed at an angle of 49 ° with the vertical, releases a projectile at an altitude of 570 m. The projectile hits the ground 7.0 s after release.
An 800-N man stands halfway up a 5 m long ladder of negligible weight. The base of the ladder is 3 m from the wall as shown. suppose that the wall-ladder contact is frictionless, wall pushes against the ladder with a force of what magnitude.
