A uniform line of charge that is 5.00cm long has a total charge of 6.00uC. An electron is at distance of 5.00cm from one end of the charge distribution, on aline that is perpendicular with the line of charge. What is the electric field at the electron.
A dolphin in seawater at a temperature of 25 °C makes a chirp. How much time passes before it hears an echo from the bottom of the ocean, 208 m below.
Find the force exerted by the plane on the pilot
A spherical object with a radius of 40.0 cm has a net charge of 37.7uC distributed uniformly throughout its volume, Using Gauss's Law, calculate the electric field 71.5 cm from the center of the sphere
A stone is thrown upward with an initial velocity of 6 m/s. What maximum height will the stone reach?
An airplane pulls a 24 kg banner on a cable as depicted in the figure below. When the plane has a constant cruising velocity the cable makes an angle of ? = 26°. What is the drag force exerted on the banner by the air
A sailor strikes the side of his ship just below the waterline. He hears the echo of the sound reflected from the ocean floor directly below 1.3 s later. How deep is the ocean at this point? Suppose the speed of sound in seawater is 1560 m/s and d..

Monochromatic light (Wavelength = 500 nm) passes through two slits and onto a screen 2.5 m away. what is the new distance between bright fringes
A 9.05 kg projectile is fired vertically upward. Air drag decreases the mechanical energy of the projectile-Earth system by 77.5 kJ throughout the projectile's ascent. How much higher would the projectile have gone were air drag negligible.
Using Newton's Version of Kepler's Third Law II Part A Pluto's moon Charon orbits Pluto every 6.4 days with a semimajor axis of 19,700 kilometers. Calculate the combined mass of Pluto and Charon. Express your answer using two significant figures. ..
The drag force on an object depends on the dimensionless drag coefficient, the density of air, the object velocity, and the frontal area of the object. By only considering units obtain a relation for the drag force
A contact lens is made of plastic with an index of refraction of 1.36. The lens has an outer radius of curvature of +1.91 cm and an inner radius of curvature of +2.41 cm. What is the focal length of lens?
