Answer:
the nucleus of the atom you have conserved almost all its mass in a very small volume
Explanation:
In Rutherforf's experiment, most alpha particles had few deflections, eg a few of them were deflected at small angles, a much smaller number deflected at large angles, and very few were deflected.
The explanation that I found for this is that if all the mass and the positive charge of the atom is in a small volume, they could specifically calculate this the relationship of the volumes,
V_atom / V_nucleo = 10⁴
Therefore, the phrase that explains the observing phenomenon is that the nucleus of the atom has concentrated almost all its mass, very small emolument and in that same volume is all the positive charge of the atoms.
In summary, the phrase that describes the process is:
the nucleus of the atom you have conserved almost all its mass in a very small volume
the volume of the container was 2.5 L at a temperature of 350K. At what temperature will the volume of the container be double its initial value, knowing that pressure remains constant ? (Find the temperature in Celsius ) Show your work below.
Answer:
Explanation:
Given the following data;
Initial volume = 2.5 L
Initial temperature = 350 K
Final volume = 2V1 = 2*2.5 = 5 L
To find the final temperature, we would use Charles law;

What is the rule you would write describing how light reflects off a mirror?
Answer: The angle of incidence equals the ray of reflection. So this law states that any ray of light that strikes an object will reflect off the object such that the striking or incident angle is identical to the reflecting angle (as measured from the normal).

A +6.33 uC charge q1 is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. What is the value of q2?
Answer:-4.1858
Explanation: I hate Acellus
If A +6.33 μC charge q₁ is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. then the value of q₂ = 4.23 μC.
What is coulomb's law ?Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law. The force of attraction between two charges are given by coulomb's law.
the law states that the force of attraction or repulsion between two point charges is directly proportional to product of magnitude of both the charge and inversely proportional to square of the distance between them.
i.e. F ∝ q₁q₂
F ∝ 1/r²
F ∝ q₁q₂/r²
F = kq₁q₂/r²
where k is proportionality constant k = 1/4π∈₀ = 8.9×10⁹
In this problem,
Given,
q₁ = 6.33×10⁻⁶ C
F = 0.115N
r = 1.44m
q₂ = ?
putting this values in the equation,
0.115 = 8.9×10⁹×6.33×10⁻⁶ ×q₂÷1.44²
q₂ = 4.23 μC.

What is the total resistance of the circuit shown below?
Answer:
R = 12 ohm
Explanation:
Resistance are in parallel
1 ÷ Resistance = 1 ÷ 20 + 1 ÷ 30
1/R = 50/600
1/R = 1/12
R = 12 ohm
A student charges a balloon and then brings it near a metal sphere hanging from the
ceiling. She brings it near the sphere, but does not touch. The sphere moves toward
the balloon. What are the charges on the balloon and the metal sphere?
a) The balloon has a positive charge and the metal sphere has a negative charge.
b) The balloon has a negative charge and the metal sphere has a positive charge.
c) Both are negatively charged.
d) Both are positively charged.
Answer:
B
Explanation:
the balloon has a negative charge and the metal sphere has a positive charge
Answer: B
Explanation:
The balloon will pick up stray electrons, so it will become negatively charged. Since it is attracted to the metal sphere, the sphere must be positively charged.

A force is acting on a 3-kg object during 5 seconds. If the object initially has a speed of 1.5m/s and after applying the force its speed is 4 m/s
Answer:
1.5 N
Explanation:
You've left us to guess what the question is. I will Assume it is what's the force?
Givens
m = 3 kg
vi = 1.5 m/s
vf = 4 m/s
t = 5 seconds
Formula
F = m * (vf - vi)/t
Solution
F = 3 * (4 - 1.5) / 5
F = 1.5 N
