An object 8.0 cm high is 18 cm from a converging lens having a focal length of 10 cm. How far is the image from the lens? What is the height of the image? Is the image real or virtual? Is the image upright or inverted? Please show all of your work and be sure to show what equations you used as well as units.
How numerous atoms does each hand contain
A 1200kg disc with radius 2.0m is rotating at 1500 rev/min when an 800 m/N braking torque is applied to the wheel. How long does it take for the disk to come to rest?
Illustrate what is the time it takes for the bullet to hit the ground, how far down range does the bullet travel, and what is the resultant velocity (in m/s) and final angle?
A ball is thrown straight up at 15.0 m/s. How much time does it take for the ball to be 5.00 m above its release point
what mass in grams of steam at 100degc must be mixed with 146 g of ice at its melting point in a thermally insulated
If the bar drops from rest, what's the magnitude of the induced emf after it's been falling for 0.4s ? (You may assume that the magnetic force on the falling bar is much less than the bar's weight.)
An electric motor with a power of 3W is used to lift a .2 kg mass a height of 0.5 meters in 3.0 seconds, since total energy must be conserved
Light of wavelength 550 nm falls on a 0.50 mm wide slit and forms a diffraction pattern on a screen 1.7 m away. Find the width of the central maximum
A 0.44 kg air cart is attached to a spring and allowed to oscillate. You are given the displacement of the air cart from equilibrium to be x = (23.1 cm) cos [(1.04s-1)t + π]. Discover the maximum kinetic energy of the cart. Discover the maximum force..
During a heavy rain, the drops are falling at a constant velocity and at an angle of 9.5° west of the vertical. What is your walking speed if the speed of the drops relative to the ground is 4.6 m/s
A proton travels with a speed of 1.7x106 m/s at an angle 32o with a magnetic field of 0.28 T pointed in the +y direction. The mass of the proton is 1.672 x 10-27 kg. What is the magnitude of the magnetic force on the proton? Answer in units of N.
A 145 g copper bowl contains195 g of water, both at 20.0°C. Avery hot 300 g copper cylinder is dropped into the water, causing the water to boil, by 5.55 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfe..
