Qué esperas que pase cuando las partículas alfa de poca energía se acerquen a un núcleo con muchos protones?
Answer:
Sufrirá una deflección en su recorrido.
Explanation:
Las partículas alfa son nucleos de He (dos protones mas dos neutrones), por lo tanto tienen una carga neta positiva.
Ahora, al acercarse al nucleo de un átomo con muchos protones y con baja energía, la partícula alfa sufrirá una deflección en su recorrido debido a las fuerzas de repulsión electrostática que siente la partícula, ya que el nucelo posee caraga positiva.

A 80 kg person buys a scale at a mall that reads weight in Newtons and can’t wait to try it out, so they open the scale on an elevator. What would the scale read if the elevator was moving upward at 6.2 m/s2?
Answer:
The scale read 1280 N.
Explanation:
Given that,
The mass of a person, m = 80 kg
We need to find the scale reading when the elevator is moving upward at 6.2 m/s².
We know that, when an elevator moves up, the reading on the scale is given by :
N-mg=ma
N=m(a+g)
Put all the values,
N = 80(6.2+9.8)
= 80(16)
= 1280 N
Hence, the scale read 1280 N.
When rutherford bombarded thin gold foil with a-particles,he found that some a-particles were deflected through large angles. Which statement explains this deflection?
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
a group of engineers have launched a space probe from earth that will land on the surface of Mars. how will the force of gravity from mars affect the space probe?
A) the force of gravity from Mars will not pull on the space probe until it reaches the planets surface.
B) the force of gravity from Mars will stop pulling on the space probe when it reaches the planet
C) the force of gravity from Mars will pull more strongly on the space probe as it gets closer to Mars.
D) the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is
Answer:D
Explanation:
The force of gravity from Mars will pull on the space probe the same amount no matter how far away it is, so option D is correct.
What is gravity?All material objects in the universe are subject to the force of gravity, also known as gravitation. The force of gravity tends to draw any two non-zero mass objects or particles toward one another. Subatomic particles and galaxy clusters are both affected by gravity, as are objects of all sizes.
Due to the law of gravity, or gravitation, which draws all objects with mass in its vicinity toward it, Mars' gravitation is a natural occurrence. Due to the planet's lesser mass, its gravity is weaker than that of Earth. On Mars, the gravitational acceleration fluctuates, but on average it is 3.72076 m/ s² (or around 38% of Earth's).
Therefore, the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is.

22) Net force is the total of all forces acting on an object. When a force is balanced and the object does not move, the net force is equal to what: A) 0 B) 10 C) 100 D) The weight of the object
Answer:
A) but be sure and read the answer.
Explanation:
If the object does not move at all, (that's an important restriction) the net force = 0. That being so, the acceleration must be 0 as well. But there is no law saying that there cannot be a constant motion and that's why the restriction is important.
how are speed and distance similar?
Answer:
When an object moves in a straight line at a steady speed, we can calculate its speed if we know how far it travels and how long it takes. This equation shows the relationship between speed, distance traveled and time taken: Speed is distance divided by the time taken.

light is shone on a diffraction grating with d=2.25 x 10^-6 m. the first order (m = 1) maximum occurs at a 15.7 angle. what is the wavelength of the light in nanometers? (hint: the answer will be between 400 and 700)
[?] nm
Answer:
608.9 nm
Explanation:
trust me cutie
The wavelength of light in nanometers is 0.017 x [tex]10^{3}[/tex] nm.
We have -
d = [tex]2.25\times 10^{-6}[/tex]
n = 1 = order
θ = 15.7 degrees
We have to calculate the wavelength of light (λ) in nanometers.
What is diffraction?Diffraction is defined as the bending or spreading of light waves as it passes through the edge of an object or through a small slit (size of slit should be very very less then wavelength of light) is called diffraction.
According to the question, we can use the following relation to calculate wavelength as -
d sinθ = nλ
λ = [tex]\frac{dsin\theta}{n}[/tex]
λ = d sinθ (since n = 1)
λ = [tex]2.25\times 10^{-6}[/tex] x sin (15.7)
λ = 0.0079 x 2.25 x [tex]10^{-6}[/tex]
λ = 0.0177 x [tex]10^{-6}[/tex] m
We know that -
1 nanometer = [tex]10^{-9}[/tex] m
1 m = [tex]\frac{1}{10^{-9} }[/tex]
0.017 x [tex]10^{-6}[/tex] m will be equal to = [tex]\frac{0.017\times 10^{-6} }{10^{-9} }[/tex] = 0.0177 x [tex]10^{3}[/tex] nm
Hence, the wavelength of light in nano meters is 0.0177 x [tex]10^{3}[/tex] nm.

7. The Voyager 1 space probe was launched in the 1970's and is now the furthest
man-made object from earth - it has actually left the solar system. At its current speed it
could travel across the US, a distance of about 4500 km in 265 seconds (a little less
than 5 minutes!) What is its average speed in kilometers per second?
PLEASE HELP I NEED THE FORMULA AND ANSWER THANK YOU!!
Answer:
v = 16.98 km/s
Explanation:
Given that,
Distance, d = 4500 km
Time, t = 265 s
We need to find its average speed. The total distance covered divided by total time taken is called average speed of an object. So,
[tex]v=\dfrac{4500\ km}{265\ s}\\\\=16.98\ km/s[/tex]
So, the average speed is 16.98 km/s.

ohms, and the equivalent resistance
of the combination is 14.5 ohms.
What is the value of R2?
(Unit = ohm)
Answer:
The value of R₂ is equal to 24.75 ohms.
Explanation:
Given that,
Two resistors, R₁ and R₂, are connected in parallel.
The equivalent resistance is 14.5 ohms
We need to find the value of R₂.
When two resistors are connected in parallel. The equivalent resistance is given by :
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{14.5}=\dfrac{1}{35}+\dfrac{1}{R_2}\\\\\dfrac{1}{R_2}=\dfrac{1}{14.5}-\dfrac{1}{35}\\\\\dfrac{1}{R_2}=0.04039\\\\R_2=\dfrac{1}{0.04039}\\\\R_2=24.75\ \Omega[/tex]
So, the value of R₂ is equal to 24.75 ohms.

A stone is dropped from the top a 45m hign building how fast will it moving when it reaches the ground? Ande what will its velocity be?
Answer:
29.7 m/s fast, velocity is 29.7 m/s
Explanation:
Applying,
v² = u²+2gs...................... Equation 1
Where v = final velocity, u = initial velocity, g = acceleration due to gravity, s = distance.
Given: u = 0 m/s (dropped from height), s = 45 m
Constant: g = 9.8 m/s²
Substitute these values into equation 1
v² = 0²+2×9.8×45
v² = 882
v = √(882)
v = 29.7 m/s.
Hence the stone will be moving 29.7 m/s fast and the velocity is also 29.7 m/s
