En una pista circular de radio 100 m, un auto le da dos vueltas en cada minuto. a) ¿Cuál es, en segundos, el periodo del movimiento del auto?
b) ¿Cuál es la distancia que recorre en cada revolución (perímetro)?
c) ¿Qué valor tiene la velocidad lineal del vehículo?
d) ¿Cuánto vale su aceleración centrípeta?
e) ¿Cuál es su velocidad angular

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
