Una persona camina una media de unos 2.000 pasos en un kilómetro y medio, quemando aproximadamente 100 calorías, según Meadows. "Medio kilo de grasa equivale a 3 500 calorías", aseguraba en 'Popsugar'. Entonces, para perder medio kilo por semana, un objetivo saludable según los expertos, necesitarías quemar 1 000 calorías por día. "Eso significa que debes apuntar unos 10 000 pasos diarios, lo que equivale a 7,5 km", añade. Cuántos kilos perdería una persona si 10 km, todos los días durante una semana. *

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.
