A 5.0 x 102 Newton weight is hung from the end of a wire of cross-sectional area 0.010 cm2. The wire stretches from its original length of 200.0 centimeter to 200.50 centimeter.
a) Compute the stress on the wire?
b) Compute what is the elongation strain on the wire?
c) Compute the Young's modulus of the wire?
A 7.9-N force pulls horizontally on a 1.6-kg block that slides on a smooth horizontal surface. What is the acceleration of the blocks
A ray of light reflects from a plane mirror with an angle of incidence of 37. compute through what angle is the reflected ray rotated
question in the 1950s an experimental train that had a mass of 2.00 104 kg was powered across a level track by a jet
A bubble floats up from the bottom of a lakeρ=1000kg/m3, up to the top. How deep is the lake
An He+ ion has one electron , just as a hydrogen atom does , but has two protons in its nucleus instead of just one .Find a formula for the wavelength lambda of an emission line for this ion in terms of the magnitude of the hydrogen ground-state ene..
Determine the period of a satellite orbiting the Moon, 190 kilometer above the Moon's surface. Ignore effects of the Earth. The radius of the Moon is 1740 kilometer
In a skating stunt known as "crack-the-whip," a number of skaters hold hands and form a straight line. find the magnitude of the centripetal force that acts on him
A particle is located at the vector position r=(4.00i+6.00j)mand a force exerted on it is given by F=(3.00i+2.00j)N. Determine the position vector for such a point.
A 2 kg mass is pushed 0.5 m into a spring with spring constant 200 N/m on a frictionless horizontal surface. Upon release, the mass travels across the surface until it encounters a rough incline. The mass moves up incline and stops at a height of ..
Two masses of 4.00 kg each, connected by a string, slide down a ramp making an angle of 45° with the horizontal. The coefficient of kinetic friction between m1 and the ramp is 0.33. The coefficient of kinetic friction between m2 and the ramp is 0...
A tank holds a layer of oil, 1.58 m thick, which floats on a layer of syrup that is 0.66 m thick. Both liquids are clear and do not intermix. A ray, The index of refraction of the syrup is closest to:
An object is found to have a weight in air of 500N. It is then tied to a string connected to a balance and immersed in water (density of water is 1000 kg/m3). The scale now reads 450 N. at last the object is immersed in oil and is found to have a ..
