Explanation: I have my answers VS. Go0gle answers (go0gle answers are pics)
(A) Both have the same day length. Well, Venus doesn't havve the same amount of days. (I already know off the top of my head, but I still searched it up)
(B) Both rotate in the same direction. In school (before Virus) they would always show diagrams of the planets on the projector and Venus doesn't rotate
(C) Both have ample water. No. Venus doesn't have much water >_>
(D) Both have a solid inner core and a liquid outer core. Yesh. In my lessons (before), Venus has a solid inner core and liquid outer core.
Identify what happens to the kinetic energy (KE) and gravitational potential energy (PE) of a rock as it falls.
KE and PE both increase.
KE and PE both decrease.
KE increases and PE decreases.
KE decreases and PE increases.
Answer:
KE increases and PE decreases.
Explanation:
POTENTIAL ENERGY (PE):
The potential energy of the rock depends upon the height of the rock, as given by the following formula:
P.E = mgh
Therefore, the potential energy will be highest at the initial point due to the highest height attained by rock. As the rock falls, its height will decrease as a result its potential energy will also decrease.
KINETIC ENERGY (KE):
The kinetic energy of the rock depends upon the velocity of the rock, as given by the following formula:
[tex]K.E = \frac{1}{2}mv^2[/tex]
Therefore, the kinetic energy will be zero at the initial point due to the zero velocity of the rock. As the rock falls, its velocity will increase as a result its kinetic energy will also increase.
Hence, the correct option will be:
KE increases and PE decreases.

smaller cylinder is pushed down
with a force of 100N through a
distance 0.2m. calculate
Links
(0)
The pressure transmitted
(ii)
The force exerted by the
piston in the larger cylinder.
Answer:
Explanation:
i )
area of small piston = 0.2 m²
Force = 100 N
pressure created on small piston
= 100 / .2 = 500 N/m²
According to Pascal's law , this pressure will be transmitted to larger cylinder .
area of larger cylinder = 5 m²
ii )
pressure = force / area
force in the large cylinder = pressure x area of large cylinder
= 500 x 5
= 2500 N .
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.

explain the forces of that affect the soccer balls path.
Answer:
yeah its correct
Explanation:
As the ball spins, friction between the ball and air causes the air to react to the direction of spin of the ball. ... Therefore, when a soccer player kicks the ball right of center the ball spins counter-clockwise and the Magnus force acts left, causing the ball to curve left.
How is speed related to kinetic energy?

Why the temperature of a resistor increase when a current pass through it
Answer:
So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibrate more. With these particles moving more, it is more difficult to for the electrons to move through the resistor.
If the amount of force from the group on the left was 235 N, what is the amount of force from the group on the right
Answer:
(F = ma ) Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration.
10. What is the acceleration due to gravity at a location

How would the particles be arranged in an object that has a high density? What about in
an object that has a low density?
Answer:
Explanation:
The particles in solids are very close together. They are tightly packed, giving solids high densities.
The particles in gases are very far apart, so gases have a very low density.

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

This graph shows a supply curve. A graph titled Supply Curve has Quantity Supplied on the x-axis, from 0 to 50 in increments of 10, and price on the y-axis, from 0 to 15 dollars in increments of 5 dollars. A line is drawn with points (10, 5 dollars), (20, 7 dollars), (30, 10 dollars), (40, 13 dollars), and (40, 15 dollars). What happens when the price of a good increases? The quantity of goods that are produced increases. The producer of the good is certain to make less money. The quantity of goods that are produced decreases. The quantity of goods that are produced stays about the same.
Answer:
A just took the quiz on edge
Explanation:
In the supply curve, when the price of a good increases, A. The quantity of goods that are produced increases.
What is supply?Supply simply means the quantity of goods and services that a supplier is willing to sell at a particular place, price and time.
In this case, when there's an increase in the price of goods, it should be noted that producers will supply more of the goods. This is done in order to generate more revenue.

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.
