Answer:
[tex]r=7\times 10^{-16}\ m[/tex]
Explanation:
The force between charges, [tex]F=-4.4\times 10^{33}\ N[/tex]
Positive charge, [tex]q_1=8\times 10^{-4}\ C[/tex]
Negative charge, [tex]q_2=-3\times 10^{-4}\ C[/tex]
We need to find the distance between charges. The force of attraction between charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
Where
r is the distance between charges
[tex]r=\sqrt{\dfrac{kq_1q_2}{F}} \\\\r=\sqrt{\dfrac{9\times 10^9\times 8\times 10^{-4}\times 3\times 10^{-4}}{4.4\times 10^{33}}} \\\\r=7\times 10^{-16}\ m[/tex]
So, the distance between charges is [tex]7\times 10^{-16}\ m[/tex].

energy is transformed into(blank)
1.Chemical,electrical,kinetic, Solar ?
2.Chemical, Electrical, Kinetic, Solar
Answer:
During photosynthesis solar energy is converted into chemical energy
Explanation:
During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.
ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.
ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.
The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.
These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).
ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.
Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.
Chlorophyll molecules entrap solar energy . There are 2 types of photo-systems in chlorophyll. These are photo-system -I and photo-system-II .
The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.
During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.
Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.
The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.
Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.
1. As you get ready for bed, you roll up one of your socks into a tight ball and toss it into the laundry
basket across the room. Then, you try to toss the other sock without rolling it up.. What effects whether
or not your socks land in the basket?
Answer:
When you toss a rolled up sock across the room, it travels faster as it becomes round and has more weight added on it and this causes the sock to travel in the direction you wish and this gives you a high chance of the sock going straight into the laundry basket, no matter how far away you are.
On the other hand, throwing a sock without rolling it up will cause the sock to just flat down as you throw it. It will travel at a low speed because it has no weight on it since it is flat, and if you try to throw it, it will atleast land 21 cm away from you. About a 0% chance of it getting in the basket.
Hope this helped! =>

Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es
A. Cinética, debido a que existen trenes elevados los cuales poseen altura y la altura está asociada con la energía cinética.
B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.
C. Rápida, porque la energía cinética es sinónimo de rápido.
D. Potencial, debido a la potencia que tiene el tren para moverse.
Solution:
La energía cinética es la energía contenida en un objeto en movimiento. La energía cinética se puede definir como la cantidad de energía necesaria para que un objeto se acelere desde el reposo hasta su velocidad final.
La energía cinética (KE) viene dada por:
KE = (1/2) * masa * velocidad²
Podemos ver que la energía cinética depende de la masa del objeto y la velocidad del objeto.
El tren de alta velocidad posee energía cinética debido a la velocidad del tren.

Explain what makes up a circuit .
Explanation:
An electrical circuit needs:
a source of electrical power (this could be a power plant or a battery)
a material along which the electricity can flow (this may be a copper wire)
something to power (this could be a bulb)
The circuit is connected in a loop. Then, the source of power pushes electrons around the wire. It lights the bulb and continues in the circuit until it is broken.
A simple circuit lights one bulb. More difficult circuits might have several switches and loops. This would allow different groups of lights to be turned on or off at the same time.

Why aren't other objects, like your pencil, drawn to you?
Let's say the force of gravity betwen you and the Earth (your "weight") is 100 pounds.
Then the force of gravity between you and a 10-pound bowling ball (sitting on the table 3-ft away from you) is about 0.000 000 049 of an ounce !
It's there, but it's too small for you to feel.
And it's not strong enough for the pencil or the bowling ball to jump up off the table, fly through the air, and stick to you.
A candle at left of a double convex lens has a blue line straight from the tip of the its flame to near the top left of the lens and then down and right through a point on a line running through the center of the lens. An orange line from the tip of the lens runs down and right through the center of the lens to intersect the blue line below the centerline of the lens below the centerline. A green line runs down and right from the tip of the flame through a point to the left of the lens on the centerline to the bottom part of the lens and then straight to intersect the blue and orange lines. Where the three lines intersect, a reduced inverted image of the candle is seen. How can the image be described? Check all that apply. smaller than the object real right-side up larger than the object upside down virtual
Answer:
Label A:
✔ virtual image
Label B:

Label C:
✔ focal point
Hope this helps!
Based on the information given in the problem, we can conclude that the image formed by the lens is: Reduced in size, Inverted, virtual.
What is lens?A lens is a curved piece of clear material, such as glass or plastic, that can bend (refract) light.
Lenses are commonly used to focus light and create images in optical devices such as cameras, telescopes, and eyeglasses.
Based on the information provided in the problem, we can conclude that the lens's image is:
Because the image is formed by the intersection of the blue, orange, and green lines, which are all smaller than the object, it is reduced in size (the candle flame).Inverted because the image is formed by the intersection of the blue and green lines, which cross above the lens's centerline, resulting in an inverted image.Because the image is formed by the intersection of blue and green lines that do not converge on the same side of the lens as the object, it is virtual. This means that the rays do not converge to form a true image that can be projected onto a screen.Thus, the image can be described as smaller than the object, inverted, and virtual.

what happens to the flow of energy into the Earth system.
Answer:
Explanation:
Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light. ... Once energy has been absorbed by the Earth system, it is transformed and transferred
The flow of energy when converted into the earth system is because of the transformation of energy.
Transformation of energy:The energy should be transferred from the sun to earth through electromagnetic waves, or radiation.
Many of the energy should be passed via the upper atmosphere and then reached the surface of the earth in two forms i.e. visible and infrared light.
In the case when the energy should be absorbed so it should be transformed and transferred.

An 80 kg diver jumps from a 10 m high platform. What is the gravitational potential energy of the diver right before they jump (top of platform)
Answer:
0 Joules.
Explanation:
Given the following data;
Mass = 80kg
Height = 10m
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
[tex] G.P.E = mgh[/tex]
Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
We know that acceleration due to gravity is equal to 9.8m/s²
But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.
Gravitational potential energy= mgh
Gravitational potential energy = 80*9.8*0
Gravitational potential energy = 0 Joules.
This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.
