When driven by a 124 Hz vibrator, a string has transverse waves of 26 cm wavelength travelling along it.

three point charges lie along the x axis as shown in the figure (no figure was given). the positive charge q1=15 mc is at x=2 m, the positive charge q2 =6 mc is at the origin, and the resultant force acting on q3 is 0.

A box is on the ramp of a parked moving-truck that forms an angle = 33 degrees with the horizontal. You are currently pushing horizontally (relative to Earth) on the box with a force Fyb=479 N to keep it from sliding down. The mass of

An AC power source has an rms voltage of 2.30 ✕ 10 2 V and operates at a frequency of 50 Hz. If a series RLC circuit is made from the power source, a 0.820 μF capacitor, a 11.0 H inductor and a 1.70 ✕

When using a double slit with light of wavelength 550 nm, it is observed that the 4-th order maximum of the interference pattern occurs at the positions of the first minimum in the diffraction pattern. If the width of the slits is 0.39 mm, what

A thin, circular disk of radius 30.0 cm is oriented in the yz-plane with its center at the origin. The disk carries a total charge of +3.00 μC distributed uniformly over its surface. Calculate the magnitude of the electric field due to the disk at

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^.
