Suppose it was discovered that Hubble's constant, H0, was smaller than previously thought. How would this affect our estimate of

Answer:

<em>The age of the universe would be larger.</em>

Explanation:

The Hubble relation states that an astronomical object's velocity is proportional to the distance between the observer and the object.

<em>v = dH₀</em>

where

  • d is the distance between the observer and the object.
  • H₀ is the Hubble constant

If the Hubble constant decreases, the velocity will decrease.

Time is determined by taking the quotient between the distance and the velocity.

<em>T = d/v </em>

Therefore, since the velocity decreased, the time increases. Thus, if H₀ was found to be smaller than thought, t<em>he age of the universe would be larger.</em>

shtirl [24]
<span>Car B has a greater momentum than car A.
Since, momentum =  mass *  velocity
mass of both car A and B is same, velocity of B is greater than A.
So, momentum of car B = 1200 * 25  =  30,000 kg-km/h  is greater than </span>momentum of car A = 1200 * 22  = 26400 kg-km/h

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.
