Mechanical(ME) energy, in physical sciences, is the sum of kinetic energy (KE) and potential energy (PE). Below are the calculation in obtaining the energies,
(1) KE = 0.5mv² = 0.5(0.1 kg) x (2 m/s)² = 0.2 J
(2) PE = md = (0.1 kg) x (1.5 m) = 0.15 J
(3) ME = KE + PE = 0.2 J + 0.15 J = 0.35 J
Thus, the mechanical energy is 0.35 Joules.
Answer:
Scandium with an ion charge of +3
Explanation:
Distance and time, distance because that's how far and time because that's how long
~Formula: Voltage= current• resistance
(V= Ir)
~Using this formula, plug in the numbers from the equation into the formula
~5=25i
~Now you have a one-step equation
~Divide by 25 on both sides and you should get your answer:
~I= 0.2 (which means current is 0.2)
