A pair of spheres is cast from the same aluminum alloy.
One of the spheres has a radius of 7.50 cm. When they are weighed,
the second sphere is found to be three times more massive. What is
the radius of the second sphere?
A pair of spheres is cast from the same aluminum alloy. One of the spheres has...
Two spheres are cut from the same rock, so they have equal densities. The first sphere’s radius is 6 cm. The second sphere is 8 times more massive than the first. What is the radius of the second sphere?
Two decorative spheres are carved from the same slab of marble. The radius of the first sphere, which has two times the mass of the second sphere, is 14.4 in. What is the radius of the second sphere in inches? in
Two uniform solid spheres have the same mass, 1.65 kg, but one has a radius of 0.256 m while the other has a radius of 0.844 m. For each of the spheres, find the torque required to bring the sphere from rest to an angular velocity of 357 rad/s in 10.5 s. Each sphere rotates about an axis through its center. a)Torque on sphere with the smaller radius. b)Torque on sphere with the larger radius. c)For each sphere, what force...
MY NUTES ASK YOUR TEACHER Two spheres are cut from the same uniform rock. The first sphere has radlus r = 4.99 cm. The mass of the second sphere is 4.60 times larger than the first.

One thousand sheets of aluminum alloy produced by the same manufacturer were examined for surface flaws. Assume surface flaws occur randomly and independently at a constant rate with an average of 4 flaws per sheet. Sheets are all the same size. a) [3 points] What is the probability that a randomly chosen sheet contains more than 1 surface flaw? b) [3 points] When 10 sheets are picked at random, what is the probability that 6 of these sheets have more...

Rolling and Torque Two spheres of the same mass are positioned on a 100 meter ramp with at 20 degree incline. Both spheres have a radius or 5 m and mass of 1000 kg (HUGE SPHERES, think Indiana Jones). The difference is how the mass is distributed. One sphere is completely solid with mass equally distributed throughout it. The second mass has all of its mass distributed at the edge of its radius in a thin shell. So, one...
One cubic meter (1.00 m3) of aluminum has a mass of 2.70 x 103 kg, and the same volume of iron has a mass of 7.86 x 103 kg. Find the radius of a solid aluminum sphere that will balance a solid iron sphere of radius 4.18 cm on an equal-arm balance. cm
