A thin film of oil (n = 1.4) of thickness 1.4micrometers. is compressed between two glass slabs (n = 1.5). White light containing wavelengths from 400 to 700nm (measured in air) is incident normally on the film. In the reflected light, which wavelengths (from long

Six identical books, ( 4cm thick and .8kg mass ), all lie flat on a table. a) How much work is needed to stack all the books one on top of the other? b) If done in 5sec, what is the power expended?

A highway curve of radius 100m, banked at an angle of 45 degrees, may be negotiated without friction at a speed of?

A 2kg box slides along a frictionless surface with a speed of 15m/s and approaches a horizontal spring with a spring constant of 2000N/m. If one end is fixed, a) How far will the spring compress in stopping the box? b) How far will the

he drawing shows a square, each side of which has a length of L = 0.250 m. Two different positive charges q1 and q2 are fixed at the corners of the square. Find the electric potential energy of a third charge q3 = -3.00 x

a) How much power,( answer given in both watts and HP ), must you exert horizontally to drag a 25kg table, 10m across a brick floor in 30s at a constant speed if the coefficient of kinetic friction is 0.550 ? b) If the table

A charge of +479 μC is fixed at the center of a square that is 0.88 m on a side. How much work is done by the electric force as a charge of +4.1 μC is moved from one corner of the square to any

An archer shoots an arrow horizontally at a target 13 m away. The arrow is aimed directly at the center of the target, but it hits 56 cm lower. What was the initial speed of the arrow? (Neglect air resistance.)

A cube has sides of length L = 0.350 m . It is placed with one corner at the origin as shown in the figure(Figure 1) . The electric field is not uniform but is given by E⃗ =( -4.21 N/(C⋅m) )xi^+( 2.61 N/(C⋅m))zk^.
