Two 22.3-cm-focal-length converging lenses are placed 16.5?cm apart. An object is placed 35.0?cmin front of one lens.
Where will the final image formed by the second lens be located? Determine the image distance from the second lens. Follow the sign conventions.
What is the total magnification? Follow the sign conventions.
A proton (m=1.67x10-27 kg) is being accelerated along a straight line at 3.6*10^5 m/sec2 in a machine. If the proton has an initial speed of 2.4x10^7 m/sec.
Describe what are the (a) magnitude and (b) direction of the boat's velocity relative to the ground? (c) How long does the boat take to cross the river?
Calculate the time constant that is equal to the time taken by a capacitor to fully charge or discharge.
Find out the magnitude of the acceleration (in m/s2) for an alpha particle in a uniform electric field with a magnitude of 100 N/C
Starting with the three particle system, find the change in electric potential energy if the alpha particle is allowed to escape to infinity while the two protons remain fixed in place. (Throughout, neglect any radiation effects.)
The company's tax rate is 30% and its discount rate is 15%. Illustrate what is the net present value of the asset?
A 0.840-kg block oscillates on the end of a spring whose spring constant is k= 42.0 N/m . The mass moves in a fluid which offers a resistive force F=-bv, where b = 0.640 N*s/m. What is the fractional decrease in amplitude per cycle?
The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.00 g/cm3.
A projectile is launched with an initial speed of40.0 m/s at an angle of 35.0° above the horizontal. What is the projectile's velocity at the highest point of its trajectory
The electric field has been measured to be horizontal and to the right everywhere on the closed box. All over the left side of the box E1 = 120 V/m, and all over the right, slanting, side of the box E2 = 250 V/m. On the top the average field is E3..
A bucket filled with dirt of mass 22 kg is suspended by a rope that hangs over a pulley of mass 31kg and radius 0.15 m. everything is at first at rest.
Two test charges are located in the x-y plane. If q1 = -2.30 nC and is located at x = 0.00 m, y = 1.040 m and the second test charge has magnitude of q2 = 4.00 nC and is located at x = 1.20 m, y = 0.750 m, calculate the x and y components
