Answer:
Avion A (10000 meters).
Explanation:
Deje que la altura de los aviones sea A y B respectivamente.
Dados los siguientes datos;
Altura A = 10000 metros
Altura B = 33300 pies
Para encontrar el avión que voló más alto, tendríamos que hacer alguna conversión de unidades.
Conversión:
Metros a centímetros;
1 metro = 100 cm
10000 metros = 100 * 10000 = 1.000.000 centímetros.
Por lo tanto, la altura A en cm = 1,000,000 centímetros
Pies a centímetros;
1 pie = 30,48 centímetros
33300 pies = 33300 * 30,48 = 1014984 centímetros.
Por lo tanto, la altura B en cm = 1014984 centímetros.
De los cálculos anteriores, podemos deducir que el avión A voló más alto.
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
A 5-column table with 4 rows. The first column labeled Trial has entries 1, 2, 3, 4. The second column labeled Ball has entries X, X, Y, Y. The third column labeled Weight has entries 1 pound, 1 pound, 2 pounds, 2 pounds. The fourth column labeled surface has entries polished tile, pavement, polished tile, pavement. The fifth column labeled Distance Ball Moved has entries empty, empty, empty, empty.
Which prediction will most likely describe how friction will affect her findings?
The distance for Trial 3 will be greater than the distance for Trial 1 partly because the weight difference of the balls will affect friction.
The distance for Trial 2 will be greater than the distance for Trial 1 because the difference in surface roughness will affect friction.
The distance for Trial 4 will be greater than the distance for Trial 2 partly because the weight difference of the balls will affect friction.
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.

Oxygen has 6 valence electrons. how many hydrogen atoms (who have 1 valence electrons) can bond with it? remember the octet rule.
Answer:
Oxygen starts with six valance electrons and ends with six valance electrons but after bonding has parts of the densities of 8 electrons
Explanation:
Chemical bonding does not increase the valance electrons. Oxygen has 6 valence electrons. Bonding is sharing of valance electrons
The electron density of two of the valance electrons of Oxygen are shared with the Hydrogen atoms. The Hydrogen atoms is turn share part of the electron density of their single electron with Oxygen.
This means that there are parts of 8 electron densities around the Oxygen. This does not increase the number of valance electrons of Oxygen. (Note the sharing is very unfair, Oxygen gets more than its
share of the electron densities of the two electrons used for the chemical bond.

Answer:
Explanation:
The equation for acceleration is
[tex]a=\frac{v_f-v_0}{t}[/tex] where vf is the final velocity and v0 is the initial velocity. Filling in:
[tex]a=\frac{5-0}{2}[/tex] so
a = 2.5 m/s/s

B Before the front of the vehicle enters the intersection. C When the front of the vehicle is even with the stop sign. D Before the front of the vehicle is even with the stop sign
Answer:
Before the front of the vehicle enters the intersection.
Explanation:
When stopping at a stop sign where there is no crosswalk or stop line, a driver should stop his/her vehicle before the front of the vehicle enters the intersection.
The front part of the vehicle comes in contact initially. On the other hand, the back part comes after that.
Hence, the correct option is (b).

B. decreasing the positive charge of the positively charged object and decreasing the negative charge of the negatively charged object
C. increasing the distance between the positively charged object and the negatively charged object
D. maintaining the distance between the positively charged object and the negatively charged object
Answer:
A. increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object
Explanation:
Increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object would make oppositely charged objects attract each other more.
How do objects attract each other?Objects attract one another when they are of different charges.
This means that objects with opposite charges i.e. + and - attract one another while objects with same charges repel.
Therefore, increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object is one way that would make oppositely charged objects attract each other more.

i want to now why volcanoes erupt
Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface.
Explanation:
Explanation:
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. ... If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.

Answer:
Particle
Explanation:
To understand photoelectric effect the physicists has to view light as a particle and not wave. The wave nature of the light could not explain the phenomenon of photoelectric effect.
Photoelectric effect is emission of electrons from a material when electromagnetic radiation(Light) is incident on it. These emitted electrons are called photoelectrons.
The explain this effect Einstein proposed that beam of light is can not be a wave propagating through space, but a swarm of discrete energy packets, called as photons.

How much force will your need to move a 200 pound refrigerator onto a truck bed that is five feet high if you use a 10 foot inclined plane?
Answer:
P = 100 lb
Explanation:
For an ideal machine:
[tex]Work\ In = Work\ Out\\(P)(L)=(W)(H)[/tex]
where,
P = Effort = Input Force = ?
L = Effort Arm = Length of inclined plane = 10 ft
W = Load to be lifted = 200 lb
H = Load Arm = Height = 5 ft
Therefore,
[tex]P(10\ ft) = (200\ lb)(5\ ft)\\\\P = \frac{(200\ lb)(5\ ft)}{10\ ft}[/tex]
P = 100 lb
