Q. The lens and mirror are separated by d = 1.00 m and have focal lengths of +80.0 cm and -50.0 cm, respectively. An object is placed p = 1.00 m to the left of the lens as shown. (a) Locate the final image, formed by light that has gone through the lens twice. (b) Determine the overall magnification of the image.(c) State whether the image is upright or inverted.
A 79, 37--long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 13 ball of clay travelling horizontally at 2.6 hits and sticks to the extremely bottom tip of the rod.
An 11.00 kg crate is placed on a horizontal conveyor belt. The materials are such that static friction = 0.47 and kinetic friction = 0.24.
To stretch a relaxed biceps muscle 2.30cm requires a force of 25 N. Find the Young's modulus for muscle tissue assume it to be a uniform cylinder of length 0.24 m and cross-sectional area 51 cm2.
A box weighing 77.0 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end. Determine the force that the table exert on the box if the weight hanging on the other side of the pulley ..
A flowerpot falls off a windowsill and falls past the window below. You may ignore air resistance. It takes time 0.420s to pass this window, which is of height 1.92 m. How far is the top of the window below the windowsill from which the flowerpot ..
The mass m =1 kg is set up as a pendulum of length 0.6m as shown on the diagram. Initially in the position of h = 0.2m above the lowest point, and the pendulum is given initial speed of 1m/s. What is the largest mass M that might be temporarily lifte..
What is the pressure (in kPa) exerted by an object that has a base which is 2cm by 4cm nd a weight of 45N.
Two points are located on a rigid wheel that is rotating with an increasing velocity about fixed axis. The axis is perpendicular to the wheel at its center. Point 1 is located on the rim and point 2 is halfway between rim and axis .at any given insta..
