Answer:
Change is for better and is necessary too. Everyone knows it but only the ones who apply it are the ones whom we call as intelligent. When a person changes in an order to make his life better, he chooses the right thing because staying put at a place in life doesn't take anyone anywhere.
Taking the example of a few infamous personalities, whom we consider as intelligent, we see a common thing that each one of them had a certain vision in life and in order to achieve it, they were ready to accept any kind of change and still are. So, this makes it clear that change is what leads us to our goal and in order to achieve it, we need to change with time.

What would make oppositely charged objects attract each other more?
increasing the positive charge of the positively charged object and increasing the negative charge of the
negatively charged object
decreasing the positive charge of the positively charged object and decreasing the negative charge of the
negatively charged object
increasing the distance between the positively charged object and the negatively charged object
maintaining the distance
tance between the positively charged object and the negatively charged object
Hurry I need answers quick I’m timed
Answer:
A). Increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object.
Explanation:
The two objects possessing opposite or unlike charges attract one another due to the electromagnetic force between the electrons, as well as, protons in order to develop ionic lattices.
As per the question, the objects having unlike charges would attract one another more when we 'escalate the positive charge of the object having a positive charge and enhance the negative charge of the object possessing negative charge.' This will lead the atoms that are losing electrons to be positively(+ve) charged and the atoms gaining electrons to be negatively
(-ve) charged. Thus, the electromagnetic force among them increases and a stronger ionic network develops leading them to attract each other more. Hence, option A is the correct answer.

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.

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.

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

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

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.
A physical science test book has a mass of 2.2 kg what is the weight on the earth
Answer:
21.582 Newtons
Explanation:
The weight of an object on Earth is equal to W=9.81M where M is the mass of the object and the acceleration due to gravity is 9.81 m/s^2. Therefore, the weight of the book on the earth is W=9.81(2.2)=21.582N, or 21.582 Newtons
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
Answer:
65 deg C = 35 deg C below boiling
35 deg C = 35 * 9 deg F / 5 deg c = 63 below boiling deg F

If the device has a resistance of 8 ohms, what additional resistor needs to be added to the circuit and how should the resistor and device be hooked up?
Explanation:
Use Ohm's Law
V / R = I
I = 5A
V = 110V
R =?
Solve for R

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

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 %.
