Auniform electric field is pointing in x direction. the magnitude of the electric field is 10 n/c. the filed makes an angle of 30 deg with a rectangular surface of area 2 x10 m calculate the electric flux crossing the surface.

Which sound characteristic is not affected by the relative motion of an object

The frequency of the fundamental of the guitar string is 320 hz. at what speed v do waves move along that string?

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
