French Physicist Leon Foucault introduced his pendulum in 1851.
By that time, it was generally accepted that the Earth rotates, but
Foucault's pendulum was the first simple demonstration that made
the Earth's <u>rotation</u> easy to prove.
Answer:
Because Moon and Mars has no atmosphere.
Explanation:
Moon and Mars has no atmosphere, so there is no friction on the falling object due to the atmosphere. The speed of the falling object is more at Moon and Mars.
When a small object impact on the surface of moon or Mars with high speed, the size of crater is large than the earth as out earth has atmosphere.
The solution for this is:
Power = Energy transferred / Time taken
Energy Transferred in one second ( Power) = mgh/s
= (1.2x10^6)(9.8)(50) = 588000000 J/s
Power = 588000000 W
Or
Power is work done / time
Work done in one second = [ rate of fall of mass]
gh = 1.2* *9.81*50 x 10^6 J/s
= 5.886e+8 W
English one > A portion is how much food you choose to eat at one time, whether in a restaurant, from a package, or at home. A serving, or serving size, is the amount of food listed on a product's Nutrition Facts, or food label (see Figure 1 below).
Different products have different serving sizes, which could be measured in cups, ounces, grams, pieces, slices, or numbers—such as three crackers. A serving size on a food label may be more or less than the amount you should eat, depending on your age, weight, whether you are male or female, and how active you are. Depending on how much you choose to eat, your portion size may or may not match the serving size.
Spanish one > Una porción es la cantidad de comida que eliges comer a la vez, ya sea en un restaurante, en un paquete o en casa. Una porción, o tamaño de porción, es la cantidad de alimento que se indica en la información nutricional o en la etiqueta de un producto (consulte la Figura 1 a continuación).
Los diferentes productos tienen diferentes tamaños de porción, que se pueden medir en tazas, onzas, gramos, trozos, rebanadas o números, como tres galletas saladas. El tamaño de una porción en la etiqueta de un alimento puede ser mayor o menor que la cantidad que debe comer, dependiendo de su edad, peso, si es hombre o mujer y qué tan activo es. Dependiendo de la cantidad que elija comer, el tamaño de su porción puede o no coincidir con el tamaño de la porción.
