Um ônibus está viajando numa estrada retilínea com a velocidade de 20 m/s. Vendo adiante um congestionamento no trânsito, o motorista aplica os freios durante 2,5 s e reduz a velocidade para 15 m/s. Supondo que a aceleração é constante durante o período de aplicação dos freios, calcule o seu valor, em m/s²?
Answer:
Aceleração = -2 m/s²
Explanation:
Dados os seguintes dados;
Velocidade inicial, u = 20 m/s
Velocidade final, v = 15 m/s
Tempo = 2.5 segundos
Para encontrar a aceleração;
Aceleração = (v - u)/t
Aceleração = (15 - 20)/2.5
Aceleração = -5/2.5
Aceleração = -2 m/s²
Nota: é negativo porque o freio aplicado está diminuindo a velocidade do carro, ou seja, a desaceleração.

4.- Una vagoneta de 1000 kg de peso parte del reposo en el punto 1 y desciende, sin rozamiento, por la vía indicada en la figura. A) Calcular la fuerza que la vía ejerce sobre la vagoneta en el punto 2, donde el radio de curvatura es de 6 m. B) Determinar el mínimo valor del radio de curvatura en el punto 3 para salvar dicho punto
Answer:
A) 49,050 N
B) 16 m
Explanation:
Question:
El dibujo de la pregunta se obtiene de un documento titulado "TRABAJO DIVERSO Y ENERGÍA" que se encuentra en línea y se presenta aquí.
La masa dada del vagón, m = 1,000 kg
La altura del punto en el que descansa el vagón, punto 1, h₁ = 12 m
A) El radio en el punto 2, el punto más bajo, R = 6 m
La fuerza, 'N', que la vía ejerce sobre el vagón en el punto 1 viene dada por la siguiente relación;
N = El peso del vagón + La fuerza de movimiento del vagón
∴ N = m × g + m × a
Dónde;
g = La aceleración debida a la gravedad ≈ 9,81 m / s²
a = La aceleración del vagón
Observamos que para el movimiento circular, la fuerza de movimiento del vagón, m × a = La fuerza centrípeta que actúa sobre el vagón = m × v² / R
∴ m × a = m × v² / R
Dónde;
v² = La velocidad del vagón en el punto 2 = 2 · g · h₁
Por lo tanto;
N = m × g + m × a = m × g + m × v² / R = m × g + m × 2 · g · h₁ / R
∴ N = 1000 × 9,81 + 1000 × 2 × 9,81 × 12/6 = 49,050
La fuerza que ejerce el vagón en el punto 2, N = 49,050 N
B) En el punto 3, tenemos;
N = m · g - m · a₃
La fuerza centrípeta en el punto 3, m · a₃ = m · v₃² / R₃
∴ La altura en el punto 3, h₃ = 4 m
El cuadrado de la velocidad en el punto 3, v₃² = 2 · g · (h₁ - h₃)
Para que el vagón esté seguro en el punto 3, la fuerza de la vía sobre el vagón, N = 0 para que el vagón permanezca en la vía actuando
Por lo tanto;
N = m · g - m · a₃ = 0
m · g = m · a₃ = m · v₃² / R₃ = m · (2 · g · (h₁ - h₃)) / R₃
∴ R₃ = (2 · g · (h₁ - h₃)) / g = (2 · (h₁ - h₃)) = 2 × (12 - 4) = 16
El radio de curvatura en el punto 3 para que el punto sea seguro es R₃ = 16 m.

Match the scenario with the justification Please help ;-; 1. Gage is beginning a low calorie diet, so he eats three servings of chicken for lunch. 2. Walter eats two servings of whole grain pasta the night before running a 5K. 3. Maggie eats half a candy bar and saves the rest for the next day. Fatty foods contain nine grams of pure fat and have little nutritional value. A. Protein contains four calories per gram of fat, so it is a low fat, high energy food. B. Carbohydrates contain four calories per gram of fat, so they need to come from grains in moderation. C. Fatty foods contain nine grams of pure fat and have little nutritional value.
Answer:
1. "Gage is beginning a low calorie diet, so he eats three servings of chicken for lunch" is equal to C: "Protein contains four calories per gram of fat, so it is a low fat, high energy food."
2. "Walter eats two servings of whole grain pasta the night before running a 5K" is equal to B: "Carbohydrates contain four calories per gram of fat, so they need to come from grains in moderation."
3. "Maggie eats half a candy bar and saves the rest for the next day" is equal to A: "Fatty foods contain nine grams of pure fat and have little nutritional value."
Explanation:
Chicken is a popular, low-fat food that provides an impressive amount of high-quality protein in just one serving. The breast is the leanest part of a chicken. A 3-ounce (85-grams) serving of roasted, skinless chicken breast contains only 3 grams of fat but provides 26 grams of protein (47).
Pasta is a fat-free, low sodium food that can fit right in with a weight loss or management plan. One cup of cooked pasta contains just 200 calories, in addition to valuable vitamins and minerals.
Sweets like candy, soft drinks, syrups, jams, and jellies are made mostly of sugars. Most of these foods do not contain many vitamins or minerals. So they are called "empty calorie" foods. Fats, oils and sweets are not bad foods.
A set of charged plates have an

potential difference V between
the plates?
(Unit = V)
pls hurry <3
Answer:
175
Explanation:
its for Acellus
The potential difference is V=1.743*10^-7
The voltage is generally referred to as the electric potential difference and it can be measured using a voltmeter. The electrical potential difference between the two plates is expressed as q=CV.
CALCULATION
we know,
q=CV
q={EA/d}*V
here q= 5.24*10^-8C
A=8.22*10^-5m^2
d=2.42*10^-8m
therefore , C={( 8.85*10^-12)*(8.22*10^-5)}/(2.42*10^-8)
C=3.006*10^-1
q=CV
q/C=V
V=1.743*10^-7

Why do you think the collapse of ecosystem was unable to recover?
Answer: When ecosystems collapse, they rapidly lose their structure and function, with dramatic changes to their size or extent, or the species that comprise them. These losses tend to homogenize and simplify the ecosystem – fewer species, fewer habitats, and fewer connections between the two. This is why when an ecosystem failure is fatal, it's unable to recover

Answer:
Option C. 4.5×10¯² N
Explanation:
From the question given above, the following data were obtained:
Charge 1 (q₁) = +5×10¯⁶ C
Charge 2 (q₂) = –4×10¯⁶ C
Distance apart (r) = 2 m
Electrical constant (K) = 9×10⁹ Nm²/C²
Force (F) =?
The magnitude of the force can be obtained as follow:
F = Kq₁q₂ / r²
F = 9×10⁹ × 5×10¯⁶ × 4×10¯⁶ / 2²
F = 0.18 / 4
F = 0.045
F = 4.5×10¯² N
Thus, magnitude of the force is 4.5×10¯² N
Which caused the greatest increase of the growth of the human population
Answer:
This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in average human age. By 2000 the population counted 6 billion heads, however, population growth (doubling time) started to decline after 1965 because of decreasing birth rates.
Explanation:
The main cause of human population growth is increased well-being.
Well-being is a term to refer to the state of satisfaction of economic, social, labor, psychological, biological needs, among others of the human.
Therefore, when civilizations and societies became more complex, many issues such as health, food, hygiene, education, government, among others, improved, giving more well-being to their inhabitants.
Well-being has evolved with society and today people have access to many things, services, and goods that give them well-being, improving their quality and life expectancy. Therefore, the correct answer is well-being.

Answer:
Aumenta la contaminación y las enfermedades.
Explicación:
El aumento de la contaminación en el medio ambiente y la propagación de enfermedades se produce si la gran cantidad de basura se tira a las calles porque la basura es el producto de desecho en el que crecen patógenos como bacterias y hongos y sabemos que las bacterias y los hongos son la principal causa de infecciones en los seres humanos. , plantas y otros animales, por eso podemos decir que tirar basura en las calles contamina tanto el medio ambiente como el suelo y causa enfermedades.
Object A has a negative charge. Object A is repelled by object B. Object B is repelled by object C and attracted to object D. What are the charges on objects B, C, & D?
Answer:
B negatively charged. C negatively charged. D positively charged.
Explanation:
If A Is negative and B is repelled by it this means that B has to have the same charge as A therefore B is negatively charged.
B is repelled By C therefore meaning they both have the same charge so C has to be negatively charged.
B is attracted to D. attraction occurs between oppositely charged objects. Therefore D has to have the opposite charge of B. Since B is negative D has to be positive in order for that attraction to occur.
