How are proton and electron associated?The number of protons within the nucleus of the atom is identical to the atomic range. The variety of electrons in an impartial atom is identical to the number of protons. The mass range of the atom (M) is equal to the sum of the wide variety of protons and neutrons inside the nucleus.
Protons definitely charged subatomic particles that live in the nucleus. Neutrons: Neutrally charged subatomic particles that are living in the nucleus. Electrons: Negatively charged subatomic debris found inside the electron shells surrounding the nucleus.
An electron is a negatively charged factor of an atom while the proton is an undoubtedly charged frame. The electrons are present out of doors the nucleus inside the orbiting shells. But the protons alongside neutrons shape the nucleus of the atom and are gifted in the middle of the atomic nuclei.

acceleration due to gravity
on its current planet?
Please help

Therefore, a = 1900/340 = 5.59
If this decay has half-life of 2 years, how many years would it take for 10.8 g Protactinium-231 to remain given an initial mass of 86.3 g?
Answer:
Time = 6 years
Explanation:
First, we will calculate the no. of half life periods required to reduce the mass of Protactinium to the given value:
[tex]m' = \frac{m}{2^{n} } \\\\2^n = \frac{m}{m'}[/tex]
where,
n = no. of half-life periods = ?
m = initial mass = 86.3 g
m' = remaining mass = 10.8 g
Therefore,
[tex]2^n = \frac{86.3\ g}{10.8\ g}\\\\2^n = 8\\2^n = 2^3[/tex]
Since the bases are the same. Therefore equating powers:
n = 3
Now we calculate the time:
[tex]Time = (n)(Half-Life)\\Time =(3)(2\ years)[/tex]
Time = 6 years

What variable do you think made this airplane fly the farthest?
Answer:
How does the weight of the nose on a paper
airplane affect the distance it will travel
when measured in centimeters?
EXPERIMENT CONCLUSION: (Explain whether or
not your data supports, or fails to support your identified
prediction. Explain why, including facts and details!)
The distance did increase when I added 1 paper clip.
However, I was surprised that the distance decreased
when I added a second paper clip. I believe this
happened because the nose of the plane became too
heavy. When the plane was released, the nose of the
plane descended much quicker. I think the plane was
more balanced in weight when only 1 clip was on the
nose.
Three resistors of resistances, R1=10Ω, R2=5Ω, R3=20Ω are connected in a circuit in such way that same amount of current flows through them. Draw a circuit diagram showing the correct connections of the three resistors, a cell of 2.5V, an ammeter and a voltmeter across R3. Calculate the potential difference across R3.
Answer
Explanation:
As the three resistors are connected in series, the expression to be used for the
calculation of RT equivalent resistance
is:
RT = R1 + R2 + R3
We replace the data of the statement in the previous expression and it remains:
5 10 15 RT + R1 + R2 + R3 + +
We perform the mathematical operations that lead us to the result we are looking for:
RT - 30Ω
The Sun creates energy through a series of steps known as:
The Sun creates energy through a series of steps known as nuclear fusion.
What is nuclear fusion?Nuclear fusion is the process by which atomic nuclei combine to form heavier nuclei, releasing a tremendous amount of energy in the process. In the Sun, this process occurs in the core, where the temperature and pressure are high enough to overcome the electrostatic repulsion between positively charged atomic nuclei. Hydrogen atoms are fused together to form helium atoms, releasing energy in the form of light and heat.
The process of nuclear fusion in the Sun can be broken down into several steps.
The first step involves the collision of two hydrogen atoms to form a deuterium atom, releasing a positron and a neutrino in the process. The deuterium atom can then combine with another hydrogen atom to form helium-3, releasing a gamma ray. Finally, two helium-3 atoms can combine to form helium-4, releasing two protons and releasing even more energy in the process.
Therefore, the process of nuclear fusion in the Sun is a complex series of steps that releases a tremendous amount of energy and is responsible for the light and heat that we receive on Earth.

A rocket pushes exhaust 10, 000 N. Without any other forces acting on the rocket, how much force does the rocket go forward? *
Answer:
10,000 N
Explanation:
Given that a rocket pushes exhaust 10, 000 N. Without any other forces acting on the rocket, how much force does the rocket go forward?
Solution
Since there is no any other additional forces, according to Newton's 3rd law of motion which state that:
In every action there will be equal and opposite reaction.
The action expelled by the rocket through its exhaust system is of 10000N.
The reactive force will be equal and opposite which will be same -10,000 N
Therefore, the rocket will go forward with a force of magnitude 10,000 N

Answer:
0.4m/s
Explanation:
[tex]F = ma[/tex] where F= force, m= mass, and a=acceleration
we also know that,
a = Δv / t where Δv = change in velocity and t = time
thus F = m ( Δv / t)

[tex]\frac{2000}{5000} = v[/tex]

Answer:
The wavelength is 1.7cm
Explanation:
Given
See attachment for wave pattern
Required
What is the wavelength
To do this, we simply calculate the distance between successive waves (see attachment 2 for point A and B)
Using the ruler, points A and B are at:
[tex]A = 0.6cm[/tex]
[tex]B = 2.3cm[/tex]
So, the wavelength is:
[tex]\lambda = B - A[/tex]
[tex]\lambda = 2.3cm - 0.6cm[/tex]
[tex]\lambda = 1.7cm[/tex]
If approximated, the wavelength is:
[tex]\lambda \approx 2cm[/tex]

An electric toy with a resistance of 2.50\,\Omega is operated by a 3.00\,\text{V} battery. (c) How much energy was delivered to the toy [over four hours]?
Answer:
Energy = 51840 J = 51.84 KJ
Explanation:
The electrical energy delivered to the toy can be found out by the following formula:
[tex]Energy = (Power)(time)\\Energy = (VI)(t)\\Enegry = VIt\\[/tex]
where,
V = Voltage = 3 V
R = Resistance = 2.5 Ω
I = Current = V/R (Ohm's Law) = 3 V/2.5 Ω = 1.2 A
t = time = (4 h)(3600 s/1 h) = 14400 s
Therefore,
[tex]Energy = (3\ V)(1.2\ A)(14400\ s)\\[/tex]
Energy = 51840 J = 51.84 KJ
g The ant has traveled 10 cm horizontally and 6 cm vertically from its starting point on a twig with a slope of 0.5. If this is the only information the ant has, what function best approximates the geometry of the twig at the point the ant is on? b) The ant can use its model of the environment to plan its movements. In particular, it wants its next step to take it no higher than 0.1 cm above its current location. How far can the ant travel horizontally and still accomplish this?
Answer:
a) a right triangle, b) x = 0.167 m
Explanation:
a) It is asked to find which geometry figure describes the movement of the ant.
Let's use trigonometry with the angles measured in radians
tan θ = y / x
tan θ = 6/10
θ = tan⁻¹ 0.6
θ = 0.54 rad
this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle
b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea
x = 0.1 / tan 0.54
x = 0.1668 m
x = 0.167 m
