Technician A says a defective vacuum modulator can cause harsh downshifts and harsh or delayed upshifts. Technician B says a defective vacuum modulator can cause soft upshifts and downshifts, as well as overheating and burnt fluid. Who is right

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.

Which describes increasing the efficiency of energy resource
