An elevator starts from rest with a constant upward acceleration and moves 1 m in the first 2 s. A passenger in the elevator is holding a 8 kg bundle at the end of a vertical cord. What is the tension in the cord as the elevator accelerates

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

What is the freezing point of radiator fluid that is 50% antifreeze by mass? kf for water is 1.86 ∘c/m.
