A convex mirror has a focal length of -48.0 cm. A 12.0-cm-tall object is located 36.0 cm in front of this mirror.
(a) Using a ray diagram drawn to scale, determine the location of the image. Note that the mirror must be drawn to scale.
cm
(b) Using a ray diagram drawn to scale, determine the size of the image. (Use a negative sign for an inverted image, positive for upright.)
Find the mechanical energy of a block- spring system having a spring constant of 1.3 N/cm and an oscillation amplitude of 2.4 cm.
Find out the average speed for the trip
Find out the magnetic induction at a point
An explosive charge imparts a velocity of 10,350 feet per second to a mortar as it exits the muzzle of mortar. If the mortar is elevated at 80 degrees what are the horizontal and vertical velocities on the mortar shell.
A luge and its rider, with a total mass of 82 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 43 m/s. Assume that they stop with the constant deceleration of 3.2 m/s2.
At what angle should the highway engineer bank. What is the magnitude of the acceleration.
Use conservation of energy to calculate the speed of the alpha particle at infinity. m/s (e) If the two protons are released from rest and the alpha particle remains fixed, calculate the speed of the protons at infinity. m/s
A 0.150 kg ball is going around in a vertical circle of radius R = 0.300 m at constant speed v. The ball is attached to a mass less ideal string which is attached to a fixed pivot point. If the tension F in the string is greater than 125 N, the st..
Find the total number of lines in a 2.90 wide diffraction grating whose third-order spectrum has the 640 hydrogen- spectral line at an angular position of 39.0.
A mass-spring system oscillates with an amplitude of 5.50cm. If the spring constant is 247N/m and the mass is 584g, determine the mechanical energy of the system
A particle oscillates with S.H.M. The maximum displacement from its mean position is 0.5 meter and frequency of motion is 10 Hz. at time t=0, particle is located at 0.15 meter and has the velocity of 24.0 m/s towards the negative x-axis.
A worker on scaffolding 65 ft above the ground needs to lift a 340 lb bucket of cement from ground to a point 30 feet above the ground by pulling on a rope weighing 5 lb/ft. How much work is required.
