How would the gravitational force between the Earth and Moon change if the distance between them was halved?
The gravitation force would be nullified; there would no longer be a gravitational force between the Earth and Moon
The gravitational force would be stronger The gravitational force would not change
The gravitational force would be weaker
Answers
Answer:
The gravitational force would be stronger.
Explanation:
Force of gravitation increases by 4 times when distance reduced by half.
When the distance between them was halved, the gravitation force would be stronger.
The gravitational force between two objects in the universe is determined using Coulomb's law which states that the force of attraction between two objects in the universe is directly proportional to the product of masses of the objects and inversely proportional to the distance between them.
[tex]F = \frac{Gm_1 m_2 }{R^2}[/tex]
where;
R is the distance between the two objects
when the distance is halved, the gravitational force becomes
[tex]F = \frac{Gm_1 m_2}{(\frac{1}{2} R)^2} \\\\F = \frac{Gm_1 m_2 }{\frac{1}{4} R^2} \\\\F = \frac{4Gm_1m_2}{R^2} \\\\F = 4 \times \frac{Gm_1 m_2 }{R^2}[/tex]
Thus, we can conclude that when the distance between them was halved, the gravitation force would be stronger.

According to Newton's Law of Cooling, if a body with temperature T 1 is placed in surroundings with temperature T 0, different from that of T 1, the body will either cool or warm to temperature T(t) after t minutes, where:
T(t) = T 0 + (T 1 - T 0)e kt
and k is a constant.
A cup of coffee with temperature 140°F is placed in a freezer with temperature 0°F. The constant k ≈ -0.0815. Use Newton's Law of Cooling to find the coffee's temperature, to the nearest degree Fahrenheit, after 15 minutes.
The temperature is about
degrees Fahrenheit.
Answers
We can substitute the given values into the equation for T, given the surrounding temperature T0 = 0, initial temperature T1 = 140, constant k = -0.0815, and time t = 15 minutes.
T = 0 + (140 - 0)e^(-0.0815*15) = 140e^(-1.2225) = 41.23°F

Calcula la velocidad en km/h y en el SI de un carguero que recorre una distancia de 0,772km en 65segundos
Answers
Answer:
La velocidad del carguero será 42,889 [tex]\frac{km}{h}[/tex], y en unidades del SI es 11,88 [tex]\frac{m}{s}[/tex]
Explanation:
La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello.
La velocidad es calculada como el cociente del espacio recorrido por un objeto entre el tiempo que este tarda en cubrir la trayectoria.
Su unidad en el Sistema Internacional de Unidades es el metro por segundo (m/s).
En este caso, el espacio recorrido es 0,772 km y el tiempo empleado para cubrir esa distancia es 65 segundos. Siendo 1 km=1.000 m y 1 h= 3.600 s. Entonces 0,772 km= 772 m y 65 s= 0.018 h. Por lo que la velocidad será:
[tex]Velocidad=\frac{0,772 km}{0,018 h}[/tex]
Velocidad=42,889 [tex]\frac{km}{h}[/tex]
En unidades de SI:
[tex]Velocidad=\frac{772 m}{65 s}[/tex]
Velocidad= 11,88 [tex]\frac{m}{s}[/tex]
La velocidad del carguero será 42,889 [tex]\frac{km}{h}[/tex], y en unidades del SI es 11,88 [tex]\frac{m}{s}[/tex]

A. mass
B. volume
C. weight
D. density
Activity 2 of 2
Which area on the image will have higher salinity and why?
Answers
Answer:
density
Explanation:
because it high salinity
Salinity and temperature of ocean water determines density of ocean water.
What is density?The density, of a substance, exists in its mass per unit volume. The symbol most often utilized for density is ρ, although the Latin letter D can also be utilized.
Increases in the temperatures of surrounding entities like ice and an increase in precipitation count fresh water into the ocean, which decreases the salinity. ocean water with lower salinity lives lighter in density and won't sink as much as denser water. This method also varies the ocean currents. The temperature has a greater influence on the density of ocean water than salinity does. So a layer of water which is having higher salinity can even float on top of the water with the one having lower salinity if the layer with more increased salinity exists quite a bit warmer than the lower salinity layer.

Why does sound propagate faster in solid bodies than in liquids and faster in liquids than in air?
PLEASE HELP
Answers
Answer:
see below
Explanation:
this is because particles in solids are packed very closely together, thus , the particles collide with each other frequently and thus transfer of energy is faster. however, particles in liquid are closely packed but not as close as in solid so the particles do not collide as frequently. thus, transfer of energy slower than in solid. furthermore, the particles in gas are spaced far apart from each other, thus the particles don't collide with each other frequently, thus transfer of energy is very slow in gas.

Solution:
Acceleration is the rate of change of velocity with time taken. The puppy has an initial velocity of 0m/s.
The formula is:
Acceleration = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]
5 = [tex]\frac{Final velocity - 0 }{10}[/tex]

Work done = forcexcos x distance
W= 100x cos 60 x2
W= 100 J
Answer:
100 J
Explanation:
Work done is the product of force and distance. The distance here is easy; it's just 2 m because it was pulled horizontally. The force, on the other hand, requires some more work, no puns intended!
We know the applied force is at an angle. Since work is parallel to the distance, the force used to calculate work must be parallel to the distance as well. This means we must use the horizontal component of the force. This, consequently, calls for the horizontal component of the angle.
Here, that horizontal component is the cosine of theta, cos θ, because the horizontal component must be adjacent to the angle. We know the angle in this case; θ is 60°. So, to find the component of the force parallel to the floor, we must multiply the total force by cos θ.
Here, θ = 60°, and the total force is 100 N. Therefore, the horizontal force equals 100 N × cos 60°. As for cos 60°, its value is 0.5. This means the horizontal force equals 100 N × cos 60° = 50 N.
From here, the work is that force, those 50 N, times the distance the box was pulled, 2 m. Therefore, work equals 50 N × 2 m = 50 N × m = 50 J.
In summary, the total work done is 50 J.

Calculate the force of gravity on a 1–kilogram box located at a point 1.3 × 10^7 meters from the center of Earth. (The value of G is 6.673 × 10^-11 newton meter^2/kilogram^2. The mass of Earth is 5.98 × 10^24 kilograms.)
Answers
The force of gravity on a 1-kilogram box located at a point 1.3 × [tex]10^{7}[/tex]meters from the center of Earth is approximately 9.81 newtons.
What is Gravity?
Gravity is a fundamental force of nature that causes physical objects with mass to be attracted to each other. It is a force that exists between any two objects in the universe, regardless of their distance or size. The strength of the gravitational force between two objects depends on their masses and the distance between them.
The force of gravity on an object depends on its mass and the distance between it and the center of the attracting body. The formula to calculate the force of gravity is:
F = G * (m1 * m2) /[tex]r^{2}[/tex]
where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.
In this problem, the object is a 1-kilogram box, the mass of Earth is 5.98 × [tex]10^{24}[/tex] kilograms, and the distance between the box and the center of Earth is 1.3 ×[tex]10^{7}[/tex] meters. The value of G is given as 6.673 × 10^-11 newton . Using these values, we can calculate the force of gravity on the box as:
F = (6.673 × [tex]10^{-11}[/tex] * (1 kg * 5.98 × [tex]10^{24}[/tex] kg) / (1.3 × [tex]10^{7}[/tex])
F = 9.81 newtons
