Abaseball pitcher throws a baseball horizontally at a linear speed of 49.4 m/s. before being caught, the baseball travels a horizontal distance of 24.7 m and rotates through an angle of 52.7 rad. the baseball has a radius of 3.43 cm and is rotating about an axis as it travels, much like the earth does. what is the tangential speed of a point on the "equator" of the baseball?

Which of these describe conduction transfer of heat between two objects that are touching transfer of heat by the actual movement of war matter the process in which energy is imitated by one of the object transmitted through space and absorbed by another a process in which energy is released by the molecules breaking apart

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
