Two different balls are rolled (without slipping) toward a common finish line. Ball 1 has an angular speed of ω 1 = 24.7 rad / s, ω1=24.7 rad/s, and ball 2 has an angular speed of ω 2 = 17.8 rad / s. ω2=17.8 rad/s. The first ball, which has a radius of 0.0738 m, 0.0738 m, is rolling along a conveyor belt that is moving at 1.94 m / s 1.94 m/s and starts out 9.32 m 9.32 m from the finish line. The second ball has a radius of 0.0508 m 0.0508 m and is rolling along the stationary floor. If the second ball starts out 6.29 m 6.29 m from the finish line, how long does each ball take to reach the finish line?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the
