120 J of work was done to lift an object 6 m above
the ground. How much force was applied to this
object and what was its mass?
Select one:
120 N, 5 kg
O
20 N, 3.04 kg
O
720 N, 12.3 kg
O 20 N, 2.04 kg
Answer:
The last option, 20 N and 2.04 kg
Explanation:
work = (force)(distance)
work = 120 joules
distance: 6 m
rearrange to find force:
120=(6)F
F= 120/6 = 20 Newtons.
Assuming its lifted from Earth's surface, the force of gravity will be 9.81 m/s^2. Let's find mass:
F=mg
m=F/g
m=(20)/(9.81)= 2.038 kg
Ralston had lots of spicy and oily food which triggered heartburn. The doctor prescribed
him Milk of Magnesia.
a. Why did the doctor prescribe milk of magnesia?
b. What is the chemical name of milk of magnesia?
Answer:
A.) The doctor decided to prescribe milk of magnesia because of the mineral Magnesium. Magnesium helps to reduce stomach acid and increases the water in the intestines which helps induce motility in the intestines. Heartburn is caused by stomach acids traveling up into your esophagus which causes that feeling of your heart burning. Milk of magnesia will help soothe this.
B.) The chemical name of milk of magnesia is magnesium hydroxide.
Explanation:
The chemical name of the milk of magnesia is magnesium hydroxide.
An antacid is any substance that is taken to decrease or neutralize the acidity of the gastro intestinal tract. We must note that the gastrointestinal tract is natural acidic.
However, hyperacidity of the gastrointestinal tract could lead to heartburn. This acidity is neutralized using an antacid such as milk of magnesia. The chemical name of the milk of magnesia is magnesium hydroxide.

Un cuerpo de 480 g de masa es atraído con una fuerza de 3.9 E-6 N por otro cuerpo de 196 g de masa. Calcula la distancia a la que se encuentran.
Answer:
La distancia entre los dos cuerpos es aproximadamente 1.269 milímetros.
Explanation:
Asumamos que ambos cuerpos son partículas, la fuerza de atracción ([tex]F[/tex]), en newtons, entre ambos cuerpos se define mediante la Ley de Newton de la Gravitación Universal, cuya ecuación es:
[tex]F = G \cdot \frac{m_{1}\cdot m_{2}}{r^{2}}[/tex] (1)
Donde:
[tex]G[/tex] - Constante de la gravitación universal, en metros cúbicos por kilogramo-segundo cuadrado.
[tex]m_{1}, m_{2}[/tex] - Masas de los cuerpos, en kilogramos.
[tex]r[/tex] - Distancia entre los cuerpos, en metros.
Si sabemos que [tex]G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}[/tex], [tex]m_{1} = 0.48\,kg[/tex], [tex]m_{2} = 0.196\,kg[/tex] y [tex]F = 3.9\times 10^{-6}\,N[/tex], entonces la distancia entre los dos cuerpos es:
[tex]r = \sqrt{\frac{G\cdot m_{1}\cdot m_{2}}{F} }[/tex]
[tex]r \approx 1.269\times 10^{-3}\,m[/tex]
Es decir, la distancia entre los dos cuerpos es aproximadamente 1.269 milímetros.
What is the dominant season in the low latitude belts? Question 6 options: Fall Spring Summer Winter
Answer:
dominant season is SUMMER
Explanation:
Latitude on the planet is the angle measurement from the so-called equator or midpoint of the Earth's sphere, therefore latitude values can range from 0º to 90º.
Low latitude values, values close to zero degrees, are very close to the central part of the planet, so when you plan to tilt in or orbit the Sun, this part is almost fixed, therefore the solar irradiation is very constant. throughout the year, consequently the dominant season is SUMMER

"Influence" between bodies is reduced as the bodies are: brought closer moved farther apart increased in charge held stationary
Answer:
moved farther apart
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
"Influence" between bodies is reduced as the bodies are moved farther apart based on Newton's law of universal gravitation.
Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.
Valerie and Greg want to bake a cake. They mix the cake batter and preheat the oven. Once the oven reaches the right temperature, they pour the batter in a cake pan, put it in the oven, and close the door. They know that while the cake is in the oven, a chemical change that involves energy occurs. Which of these statements describes the amount of energy in the oven while the cake is baking?
Answer: They know that while the cake is in the oven, a chemical change that involves energy occurs.
Explanation:
The total amount of energy stays the same, but it changes from one form to another. The correct option is D.
What is law of conservation of energy?According to the rule of conservation of energy, energy can only be transformed from one form of energy to another and cannot be created or destroyed.
This indicates that unless energy is added from the outside, a system always has the same quantity of energy.
The law of conservation of energy, which is found in physics and chemistry, stipulates that the total energy of an isolated system stays constant over time.
Greg and Valerie want to make a cake. They prepare the oven and mix the cake mixture. They are aware that a chemical shift involving energy takes place while the cake is baking.

4. Un móvil lleva una velocidad de 75 m/s, en dicho momento aplica los frenos durante tiempo de 15 segundos hasta detenerse. ¿cuál será la aceleración del frenado? ¿cuál es la distancia que recorre hasta detenerse?
Answer:
a = 5 m / s² and x = 562.5 m
Explanation:
Let's apply the kinematics relations
v = v₀ + at
v² = v₀² + 2a x
In this case, as the car stops, its final speed is zero (v = 0) and the acceleration must be opposite to the speed, that is, negative
0 = v₀ - a t
a = v₀ / t
let's calculate
a = 75/15
a = 5 m / s²
let's look for the distance
0 = v₀² - 2a x
x = v₀² / 2a
let's calculate
x = [tex]\frac{75^2}{2 \ 5 }[/tex]
x = 562.5 m

Which represents an endothermic reaction? wood burning in a fire splitting a gas molecule using a heat pack on an injury TNT exploding
Answer:
b
Explanation:
The statement which represents an endothermic reaction is using a heat pack on an injury.
What is an endothermic reaction?An endothermic reaction is a type of chemical reaction that absorbs heat energy from the surroundings. In other words, in an endothermic reaction, energy is taken in from the environment as the reaction proceeds, resulting in a decrease in the temperature of the surroundings.
Endothermic reactions require an input of energy to occur, usually in the form of heat, light, or electricity. This energy is used to break the bonds between atoms or molecules in the reactants, and the products formed have higher potential energy than the reactants. The excess energy is absorbed from the surroundings to compensate for this increase in potential energy.
Examples of endothermic reactions include melting ice, evaporating water, and baking soda reacting with vinegar to produce carbon dioxide gas. These reactions require an input of energy to occur and absorb heat from the surroundings, resulting in a decrease in the temperature of the surrounding environment.
Here in this question,
Endothermic reactions absorb heat energy from the surroundings, meaning that they require energy input to proceed. In the case of using a heat pack on an injury, energy is required to activate the reaction that produces heat and provides warmth to the injured area. This process absorbs heat from the environment, making it an endothermic reaction.
In contrast, wood burning in a fire and TNT exploding are exothermic reactions because they release heat energy into the surroundings, which means that they produce heat as a byproduct. The splitting of a gas molecule is not an endothermic or exothermic reaction, but rather a chemical reaction that can be either endothermic or exothermic depending on the specific reaction and conditions involved.
Therefore, The correct answer is using a heat pack on an injury.
