Answer:
The speed of the car before it began to skid is 47.56 m/s.
Explanation:
We can use kinematics to solve this problem.
We are given three known variables:
- Δx = 290 m
- a = -3.90 m/s²
- v = 0 m/s (final velocity is 0 m/s because the car skids to a stop).
We can use this kinematic equation to <u><em>solve</em></u><em> for the initial velocity</em>, v₀.
Substitute the known variables into the equation.
- (0)² = v₀² + 2(-3.9)(290)
- 0 = v₀² - 2262
- 2262 = v₀²
- <u>v₀ = 47.56 m/s</u>
The speed of the car before it began to skid is 47.46 m/s.
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.
buena suerte y tuve que traducir esto
Answer: D
Neither A nor B
Explanation:
In order to check the clearances for rod and main bearings, you need a set of micrometers and a dial-bore gauge
Measuring the inside diameter of a main or rod bearing will require a dial bore gauge. The best ones to use are accurate down to 0.0001-inch.
So, both technician A and B are incorrect
This thermal energy flows as heat within the box and floor, ultimately raising the temperature of both of these objects.
Answer:
When an electric field is established across the metallic solid, the free electrons are accelerated. ... Thus, an electron acquires additional non-random velocity opposite to direction of field. This velocity is responsible for transport of electrons in conductors.
