large amounts of energy are converted to small amounts of mass. small amounts of energy are converted to large amounts of mass. small amounts of mass are converted to large amounts of energy. large amounts of mass are converted to small amounts of energy. mass is destroyed and energy is created. energy is destroyed and mass is created.
Answer:
small amounts of mass are converted to large amounts of energy
Explanation:
According to the mass-energy equivalence, which Albert Einstein initially proposed as a general principle. It was revealed that mass and energy are connected and that a "small amount of mass can be converted into enormous amounts of energy."
Using the formula E=mc^2. This means Energy equals mass times the speed of light squared.
Hence, it is true that "small amounts of mass are converted to large amounts of energy."

Two charges, each q, are separated by a distance r, and exert mutual attractive forces of F on each other. If both charges become 2q and the distance becomes 3r, what are the new mutual forces
Answer:
F = ⅔ F₀
Explanation:
For this exercise we use Coulomb's law
F = k q₁q₂ / r²
let's use the subscript "o" for the initial conditions
F₀ = k q² / r²
now the charge changes q₁ = q₂ = 2q and the new distance is r = 3 r
we substitute
F = k 4q² / 9 r²
F = k q² r² 4/9
F = ⅔ F₀

A body, which floated in water, sank when put in kerosene. Why
did it happen?
Answer:
The answer is below
Explanation:
The density of an object is its mass per unit volume, that is the ratio of mass to volume occupied. It is given by:
Density = mass / volume
A body floats in a liquid when the buoyant force (weight of displaced liquid) is more than the weight of the body, it sinks if the buoyant force is less than the weight of the body and remains at the same depth if the buoyant force is equal to the weight of the body.
The density of Kerosene is less that the density of water. So a body displaces a greater weight of water than that of kerosene, and hence floats in water but sinks in kerosene.

Explanation:
An object is to the left of a convex mirror. Describe the two rays needed to indicate the location and height of the image. Additionally, state what side of the mirror the image is on and whether it is real or virtual.
Answer:
1) a ray parallel to the optical axis that after passing through the lens passes through the focal length
2) a ray that passes through the center of curvature, this ray does not have any deviation
real image d_{objet} > f
Explanation:
In geometric optics, you can find the position of the image by geometric method, we draw two rays
1) a ray parallel to the optical axis that after passing through the lens passes through the focal length
2) a ray that passes through the center of curvature, this ray does not have any deviation
3) a ray that passes through the focal length and when passing the lens comes out horizontally
The interceptor point is where the image is
To determine if the image is real or virtual, when the object is at a greater distance than the focal length, the image is real and when it is at a shorter distance, the image is virtual.
The virtual image is formed on the same side as the object
real image d_{objet} > f

Explain how a compass can get you out of the woods if you are lost.
Answer:
Explanation:
A compass always (or usually always) points to the magnetic north. If you came in from the south east and got lost, it will point north and you can adjust the way you travel by going 90 off of where the compass points. Keep walking on that line until you hit a place that you recognize and there is no more need for the compass.
Answer: The first thing you have to do is locate east on your compass housing. Turn your compass until you see that east lines up directly with your direction of travel arrow. Quite simply, that is the direction you want to walk. You can do this for any direction.

What is the temperature difference between 65 degree Celcius and 212 degree Farenheit.
Find the temperature difference in both Celcius and Farenheit scale.
Answer:
65 deg C = 35 deg C below boiling
35 deg C = 35 * 9 deg F / 5 deg c = 63 below boiling deg F
(1 deg C = 9/5 deg F)
212 - 63 = 149
So 65 deg C = 149 deg F
Not sure exactly what's wanted, but
212 deg F = boiling
65 deg C = 149 deg F
Check: 65 * 9/5 + 32 = 149 as found above

pls how do i do this my grades are due today:(! i have to pass this class
Answer:
B, A, E, D, C
Explanation:
If the arrow points to the right, then the force is positive.
If the arrow points to the left, then the force is negative.
Also, remember that the force does not relate (necessarily) to the mass, so the different blocks having different masses is not an important factor in this problem.
Let's find the force in each block.
A)
Here we have a positive force of 3N and a negative force of 1N
Then the net force (the sum of all the forces) is:
F = 3N - 1N = 2N
B)
Here we have two positive forces, one of 1N and other that I cant see, I guess that it is 3N
Then the net force is:
F = 1N + 3N = 4N
C)
Here we have two negative forces of 2N
Then the net force is:
F = - 2N + ( - 2N) = -4N
D)
Here we have a single force of 2N that is negative, then the net force is:
F = -2N
E)
Here we have a negative force of 3N and a positive force of 2N
then the net force is:
F = -3N + 2N = -1N
Then, the order of greatest to least (from positive to negative) is:
B, A, E, D, C

En una práctica un beisbolista lanza verticalmente la bola con una velocidad de 12m/s en dirección ascendente. ¿Cuál será la altura máxima que alcanza la pelota?
Answer:
Thus, the maximum height is 7.35 m.
Explanation:
initial velocity, u = 12 m/s
acceleration due to gravity, g = 9.8 m/s^2
Velocity at maximum height, v = 0 m/s
Let the maximum height is h.
Use third equation of motion
[tex]v^{2}=u^{2}-2 g h\\0 = 12\times 12 - 2 \times 9.8\times h\\h =7.35 m[/tex]

Beryllium-11 has a half-life of 13.81 s. What percent of the initial sample will remain aft er 30.0 s?
Answer:
Let N0 be the initial atoms of Be11
N0 / 2^1 = N0 / 2 Number of Be11 after 1 half-life
N0 / 2^2 = N0/ 4 Number of Be11 after 2 half-lives
30/13.81 = 2.17 half lives
N0 / 2^2.17 = N0 / 4.51 = .222 N0 or 22.2 % of atoms remain
The percentage of the initial sample that will remain after 30.0 s is 22.2 % of atoms remain.
What is half-life?A half of existence is the duration required for something to reduce in size by half. The phrase is most frequently used in reference to radioactive decay, which takes place as unstable atomic particles weaken. There are 29 known factors that can operate in this way.
Every chemical has a unique half-life. Since carbon-10, for instance, has a half-life of only 19 seconds, it is impossible for this isotope to be found in nature.
Let No of the initial atoms of Beryllium-11
No / 2¹ = N0 / 2 Number of Be11 after 1 half-life
No / 2² = N0/ 4 Number of Be11 after 2 half-lives
30 / 13.81 = 2.17 half lives
No / 2²·¹⁷ = N0 / 4.51 = .222 N0 or 22.2 % of atoms remain
Therefore, the percentage of the initial sample will remain after 30.0 s is 22.2 %.

a.If the hockey player exerted twice as much force (9.00 N) on the puck over the
same distance, how would the amount of work the stick did on the puck be
affected
Answer:
The work done is doubled.
Explanation:
The work done is defined as the product of the force and the displacement in the direction of force.
Work = force x displacement.
As the force is doubled and the displacement remains same, so the work done is also doubled.
Work done is a scalar quantity and its SI unit is Joule.
Astronomical observatories have been available since ancient times, and many cultures set aside special sites for astronomical observations. The thing modern observatories have that was missing from these older observatories until about 1610 was __________________. Group of answer choices
Answer:
The answer is "telescopes".
Explanation:
Throughout ancient times, astronomical observatories have indeed been available, and so many historical locations were reserved for astronomical observations. All contemporary astronomers lacked within those older telescopes were lenses until 1610. A telescope is indeed an instrument used to view far-off objects. Telescopes often are being used to look at planets and stars.

A circuit has a resistance of 8 Ohms. the voltage supplied to the circuit is 14 volts. what is the current flowing through it?
Answer:
e jiio7ruetw5258o0pomnmitwq2690okm ,,kkkiiht44456
The current across a certain resistor can be found using Ohm's Law, as before:
Vi = RiIi
where:
Vi is the voltage drop across the resistor
Ri is the resistance of the resistor
Ii is the current through the resistor
In this problem:
R2 = 8Ω is the resistor we are considering
V₂ = 110V is the voltage drop across that resistor (in a parallel circuit, the voltage drop is the same across each resistor)
Solving for I, we find the current through it:
I₂ = V₂/R₂ = 110/8 = 13.7A (see that "V₂/R₂" and "110/8" part as fraction)

A ticker timer makes 50 dots per second. When a body is pulled by a tap through the timer, the distance between the third and fourth dot is 3cm and the distance between the fourth and fifth dot is 4cm.what was the acceleration of the body?
Answer:
The acceleration is 1 cm/s^2.
Explanation:
The acceleration is defined as the rate of change of velocity.
Here, initial velocity, u = 3/1 = 3 cm/s
final velocity, v = 4/1 = 4 cm/s
time, t = 1 s
Let the acceleration is a.
Use first equation of motion
v = u + at
4 = 3 + 1 x a
a = 1 cm/s^2
