se cruzan 2 líneas de arvejas, una con las flores color púrpura y la otra con las flores blancas. Se obtuvo la primera generación y todos los individuos obtenidos fueron con flores púrpura. Después se cruzaron entre sí los individuos de la F1 y se obtuvieron 100 individuos en la F2. ¿Cuántos individuos de la segunda generación produjeron flores púrpura y cuántos individuos flores blancas.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

i know can you plzz me with this question im sorry i didt answer your question i just need hel.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
