The 200-mm-radius disk rolls without sliding on the surface shown. knowing that the distance bg is 160 mm and that at the instant shown the disk has an angular velocity of 8.4 rad/s counterclockwise and an angular acceleration of 2.2 rad/s2 clockwise, determine the acceleration of a. (round the final answer to two decimal places.)
A basketball rolls off a deck that is 3.2 m from the pavement. The basketball lands 0.75 m from the edge of the deck. How fast was the basketball rolling? Seema lists the given values in a chart and determines that the unknown value is vx. given: value: change in y 3.2m ay -9.8 m/s2 […]
Treating the ladder as a uniform rod of length 3.66 m and mass 10.6 kg, find the torque the person must exert on the ladder to give it an angular acceleration of 0.243 rad/s2.
Where qvis is the energy of activation for viscous flow, a is a temperature-independent constant, and r and t are, respectively, the gas constant and the absolute temperature. a plot of ln η versus 1/t should be nearly linear, and with a slope of?
What is the probability that an electron in the 1s state of a hydrogen atom will be found at a distance less than a/4 from the nucleus?
Tim adds salt as he starts to heat a pot of water to cook pasta. When the water is boiling, he notices the salt has dissolved explain y
A bird is flying due east, it distance from a tall building is given by x(t) = 28m +(12.4m/s)t + (0.045 m/s^3)t^3. what is the instantaneous velocity of the bird at t = 8s
How would you change the distance between two charged particles to increase the electric force between them by a factor of 16? a) reduce the distance by a factor of 4. b) increase the distance by a factor of 4. c) increase the distance by a factor of 16. d) reduce the distance by a […]
A sample of an ideal gas at 1.00 atm and a volume of 1.94 l was placed in a weighted balloon and dropped into the ocean. as the sample descended, the water pressure compressed the balloon and reduced its volume. when the pressure had increased to 55.0 atm, what was the volume of the sample? […]
The same double-slit experiment is then immersed in water (with an index of refraction of 1.33) and repeated. when in the water, what happens to the interference fringes?
