The correct order of these types of radiation from highest penetrating power to lowest penetrating power is gamma, beta, and alpha. The correct option is C.
Among gamma, beta, and alpha radiation, gamma radiation has the shortest wavelength. This is because gamma radiation consists of high-energy electromagnetic waves, similar to X-rays and light, but with even shorter wavelengths.
In terms of other properties:
Alpha radiation consists of particles called alpha particles, which are helium nuclei (two protons and two neutrons) that are emitted from the nucleus of an atom during radioactive decay. Alpha particles are relatively large and heavy, and they have a positive charge. They have a short range in air and can be stopped by a piece of paper or human skin, but they can cause significant damage to living tissue if they are inhaled or ingested.
Beta radiation consists of particles called beta particles, which are high-energy electrons or positrons that are emitted from the nucleus of an atom during radioactive decay. Beta particles are smaller and lighter than alpha particles, and they have a negative charge. They have a longer range in air than alpha particles, but they can be stopped by a thin sheet of metal or plastic.
Gamma radiation, as mentioned earlier, consists of high-energy electromagnetic waves. Gamma rays are similar to X-rays but have even higher energies and shorter wavelengths. Gamma rays have the longest range in air and require dense materials, such as lead or concrete, to stop them. Gamma radiation is the most penetrating of the three types of radiation and can cause damage to living tissue if exposure is prolonged.

Find the following answer based on the image.
We are given:
Mass of Neptune = 1.03 * 10²⁶ kg
Distance from the center of Neptune (r) = 2.27 * 10⁷
now, computing the value of the acceleration due to gravity (g)
Finding g:
We know the formula:
g = G(mass of planet) / (r)²
g = [6.67 * 10⁻¹¹ * 1.03*10²⁶] / (2.27*10⁷) [since G is 6.67*10⁻¹¹]
g = (6.87 * 10¹⁵) / (5.15 * 10¹⁴)
which can be rewritten as:
g = (6.87 * 10¹⁵ * 10⁻¹⁴) / 5.15
g = (6.87 * 10¹⁵⁻¹⁴) / 5.15
g = (6.87/5.15) * 10
g = 1.34 * 10
g = 13.4 m/s² (approx)

A projectile is shot horizontally from the edge of a cliff, 400 m above the ground. The projectile is traveling horizontally at 65 m/s the moment it leaves the cannon.
What is the initial vertical velocity of the projectile?
Determine the time taken by the projectile to hit the ground.
How far does the projectile land from the base of cliff?
Find the vertical component of the velocity just before the projectile hits the ground.
What is the magnitude of the final vector velocity the instant before it hits the ground?
What is the direction of the final vector velocity the instant before it hits the ground?
Answer:
a) [tex]v_{oy}[/tex] = 0, b) t = 9.035 s, c) x = 587.275 m, d) v_y = -88.54 m / s,
e) v = 109.84 m / s, f) θ = -53.7º
Explanation:
This exercise is a projectile launch
a) as the projectile is launched horizontally, its initial vertical velocity is zero
[tex]v_{oy}[/tex] = 0
b) let's use the relation
y = y₀ + v_{oy} t - ½ g t²
when reaching the ground y = 0 and the initial vertical velocity is v_{oy}=0
0 = y₀ + 0 - ½ g t²
t = [tex]\sqrt{ \frac{2 v_o}{g} }[/tex]
t = [tex]\sqrt{ \frac{ 2 \ 400 }{ 9.8} }[/tex]
t = 9.035 s
c) the horizontal distance is
x = v₀ₓ t
x = 65 9.035
x = 587.275 m
d) the vertical speed when touching the ground
v_y = [tex]v_{oy}[/tex] -gt
v_y = 0 - 9.8 9.035
v_y = -88.54 m / s
the negative sign indicates that the velocity is directed downwards
e) the velocity at this point
v = [tex]\sqrt{ v_x^2 + v_y^2}[/tex]
v = [tex]\sqrt{65^2 + 88.54^2}[/tex]
v = 109.84 m / s
f) the direction of the velocity
let's use trigonometry
tan θ = v_y / vₓ
θ = tan⁻¹1 v_y / vₓ
θ = tan⁻¹ (-88.54 / 65)
θ = -53.7º
this angle is measured clockwise

Describe a way that gravity influenced the formation of the solar system, with the planets orbiting the sun.
Gravity influenced the formation of the solar system, with the planets orbiting the sun.
What is Gravitational Force ?Gravitational force is force of attraction between two masses. Gravitational force(F) between two bodies is directly proportion to the product of masses(m₁,m₂) of two bodies and inversely proportional to square of distance(r) between them. mathematically it is written as,
F [tex]\alpha[/tex] m₁.m₂
F [tex]\alpha[/tex] 1/r²
F = G m₁,m₂÷r²
where G is gravitational constant, whose value is 6.6743 × 10⁻¹¹ m³ kg-1s⁻².
Force is expressed in Newton N in SI unit. its dimensions are [M¹L¹T⁻²].
According to Kepler's first law of motion, every planet is moving in an elliptical orbit with sun has situated at one of the foci of the orbit.
when a planet moves in the orbit around the sun, it moves in a stable orbit. in this orbit , centripetal force is equal to centrifugal force, in this case centripetal force appears as gravitational force. Means Gravitational force between sun and planet balances the centrifugal force which is outwards. In such a way gravity influenced the formation of the solar system.
Hence gravity plays crucial role in the formation of solar system.

A car drives in a circle at 56 km/hr. Which of
the following accurately describes the
motion of the car? The car's -
speed and velocity are both constant.
velocity is constant but speed is changing.
speed is constant but velocity is changing.
speed and velocity are both changing.
Answer:
Speed is constant but velocity is changing
Explanation:
Speed is a scalar quantity, meaning magnitude only. Velocity is a vector quantity, meaning magnitude and direction. If you're moving in a circle at a constant speed, the speed is constant but the direction is constantly changing. Therefore, the speed is constant but velocity changes.
A force of 900 N pushes a wedge 0.10 m into a log. If the work done on the log is 50 J, what is the efficiency of the wedge?
Answer:
I'm fairly certain it's 1,800
Explanation:
The efficiency of the wedge with force F=900 N displaces the wedge 0.10 m is 55.55% or 56%.
What is the efficiency of the machine?The efficiency of the machine equals the ratio of output energy and input energy. It is also defined as the ratio of work done on a load by the machine to the work done on the effort by the machine.
A load is defined as the weight lifted by the machine. The effort is defined as the force applied to bring the desired change in the load. Work done is defined as the product of force and displacement.
The efficiency, η = Output power / Input power, and the highest efficiency of the machine is equal to one. The efficiency of the machine has no unit. The efficiency η = (Actual work done / Ideal work done) × 100.
From the given,
Force = 900 N
Displacement = 0.1 m
Work done = F × s = 900×0.1 = 90 J
Actual work done = 50 J
Efficiency,η = (50/90) × 100
η = 55.55 %
Thus, the efficiency of the wedge is 55.56%.

Balok diam diatas bidang miring pada sudut kemiringan 40° balok mulai bergerak,tentukan koefisien gesek statis antara balok dan bidang miring
Answer:
0.84
Explanation:
m = Massa balok
g = Percepatan gravitasi
[tex]\theta[/tex] = Sudut kemiringan
[tex]\mu[/tex] = Koefisien gesekan statik antara balok dan bidang miring
Gaya balok karena beratnya diberikan oleh
[tex]F=mg\sin\theta[/tex]
Gaya gesekan diberikan oleh
[tex]f=\mu mg\cos\theta[/tex]
Kondisi dimana balok mulai bergerak adalah ketika gaya balok akibat beratnya sama dengan gaya gesek pada balok.
[tex]mg\sin\theta=\mu mg\cos\theta\\\Rightarrow \mu=\dfrac{mg\sin\theta}{mg\cos\theta}\\\Rightarrow \mu=\tan\theta\\\Rightarrow \mu=\tan40^{\circ}\\\Rightarrow \mu=0.84[/tex]
Koefisien gesekan statik antara balok dan bidang miring adalah 0.84.

prove that total mechanical energy is always constant
Explanation:
We know that the overall mechanical energy of a device stabilizes in the absence of any external force. We know that that the total of potential and kinetic of the freely velocity vector remains same. ,So mechanical energy of a body, underneath gravitation, remains constant.
