Prism of refractive index 1.53 is placed in water of refractive index 1.33. If the angle of the prism is 60. Calculate the angle of minimum deviation in water?
We are not normally aware of the gravitational or electric force between two ordinary objects. What is the reason in each case? Give an example where we are aware of each one and why.
A loudspeaker of mass 23-{rm kg} is suspended a distance of h = 1.80- {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.10- {rm m}. What is the tension T in each of cables.
A solid cylinder with mass and radius, rotating with angular speed about an axis throughout its center, is set on the horizontal surface for which the kinetic friction coefficient is.
An oscilloscope shows a steady sinusoidal signal of 5 Volt peak to peak, which spans 5 cm in vertical direction on the screen. What will be observed on the oscilloscope screen
Two large, parallel, conducting plates are 21cm apart and have charges of equal magnitude and opposite sign on their facing surfaces. An electrostatic force of 4.1 x10-15 N acts on an electron placed anywhere between the two plates.
Light is incident on a slit 0.750 mm wide. On a screen 2.00 m away, the distance from the central maximum to the first minimum is 1.35 mm. compute the wavelength of the light.
suppose that the engineer is at x = 0 when, at t = 0, he first spots the locomotive. Sketch x(t) curves for the locomotive and high-speed train for the cases in which a collision is just avoided and is not quite avoided. Do this on paper. Your ins..
Two balls of identical mass of 1.152 kg and with identical charges placed on them hang from the ceiling on identical strings of lengths 1.310 m. If the angle with respect to the vertical that the strings form is 24.5 degrees.
Two concentric hollow metal spheres have radii r1=1.50E-2 m and and r2=6.80E-2 m. At a point 9.80E-2 m from the center of the spheres, the electric field is directed outward and has a magnitude 2.08E+2 N/C. At a distance 5.80E-2 m from the center,..
Vector A has a magnitude of 8 units and makes an angle of 45.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. (Using graphical methods), find (a) vector sum A + B and (b) vector diffe..
