Answer:
Red
Explanation:
Red is a colour which has the lowest frequency. Violet has the highest frequency. Frequency has a direct relationship with energy. This means the higher the frequency, the higher the energy. Red has the lowest energy of all the colors too.
The frequency and Energy has an inverse relationship with the wavelength.
However Red has the longest wavelength of about 620 - 780 nanometer.

b. If you double the frequency of the sound wave, determine its speed.
c. What happens to the wavelength if you cut the frequency in half? How do you know?
I'll throw in brainiest too.
Answer:
a. 340.13 m/s b. 680.26 m/s c. our wavelength doubles
Explanation:
a. speed of wave, v = fλ were f = frequency = 301 Hz and λ = wavelength = 1.13 m.
v = fλ = 301 Hz × 1.13 m = 340.13 m/s
b. If we double the frequency then f = 2 × 301 Hz = 602 Hz
v = fλ = 602 Hz × 1.13 m = 680.26 m/s
c. If the speed of the wave is still 340.13 m/s, if we cut the frequency in half, then frequency now equals f = 301 Hz/2 = 150.5 Hz.
Since v = fλ,
λ = v/f = 340.13 m/s ÷ 150.5 Hz = 2.26 m.
Since our initial wavelength λ₀ = 1.13 m,
λ/λ₀ = 2.26 m/1.13 m = 2.
So, λ = 2λ₀ our wavelength doubles

Answer:
I₂ = I₀ 1/4
Explanation:
For this exercise we use the definition of intensity which is the power per unit area
I = P / A
The emitted power is constant, so
P = I A
We can write this equation for the start and end point with index 2
I₀ A₀ = I₂ A₂
I₂ = I₀ A₀ / A₂
The spot area is the area of the circle
A₀ = π r₀²
We substitute
I₂ = I₀ r₀² / r₂²
It indicates that the radius of the spot is twice the initial radius
r₂ = 2 r₀
I₂ = I₀ (r₀ / 2 r₀)²
I₂ = I₀ 1/4

If a system absorbs 300.5J of heat and performs 1.50kJ of work on the surroundings, what is the ΔE?
Complete question:
If a system absorbs 300.5J of heat and performs 1.50kJ of work on the surroundings, what is the change in internal energy of the system ΔE?
Answer:
Change in internal energy of the system is 1800.5 J
Explanation:
Given:
heat transferred to the system, Q = 300.5J
work done on the surroundings, W = 1.50kJ
Change in internal energy of the system ΔE, can be calculated by applying thermodynamic equation of change in internal energy, work done and heat transferred.
ΔE = Q + W
Where;
ΔE is change in internal energy
Q is heat transfer
W is work done
ΔE = 300.5 J + 1500 J
ΔE = 1800.5 J
Therefore, change in internal energy of the system is 1800.5 J
Answer:
The intern energy of the system is -1199.5 J
Explanation:
Given:
System absorbs 300.5 J of heat
Performs 1.5 kJ = 1500 J of work on the surroundings

Two balls of the same shape and size have charges of +8 and-2. The balls are brought together, allowed to touch, and then separated. What is the net charge on each ball now?
Explanation:
Initially, two balls of the same shape and size have charges of +8 and-2. The balls are brought together, allowed to touch, and then separated.
When they are touched, the total charge is evenly distributed among the whole surface and they behaves as if it is a single piece. Net charge at this point is +8-2=6 C. When they are separated, each ball will have a charge of 6/2 = 3 C.
When two identical balls with charges of +8 and -2 are brought into contact and then separated, each ball ends up with a net charge of +3, due to the conservation of charge and even distribution across identical conducting surfaces.
When two balls of the same shape and size with charges of +8 and -2 are brought together, allowed to touch, and then separated, the net charge on each ball is a result of the equal distribution of the total charge across both balls. Initially, the total charge is the sum of +8 and -2, which equals +6. Since the balls are identical and they come into contact, this total charge of +6 is evenly divided between them. Therefore, after they are separated, each ball will have a net charge of +3.
This occurs because, when conducting objects touch, charges redistribute themselves evenly across the surfaces of the objects until they reach an equilibrium while maintaining the conservation of charge. In simpler terms, the total quantity of charge is conserved, and since the two balls are identical, the charge divides evenly.

Where would you expect to have more touch receptors: on the palm of your hand or on the back of your hand? Explain your reasoning
Help help help
Answer:
ive answered this
Explanation:
please check your previose question
The palm of the hand has more touch receptors than the back, making it more sensitive to touch. This density of receptors allows the palm to better distinguish two closely spaced points. The difference in receptor density and receptive field sizes results in the increased tactile sensitivity of the palm.
In terms of touch receptor density, you would expect to have more touch receptors on the palm of your hand compared to the back of your hand. This is because areas of the skin with a high density of touch receptors, such as the palms, are more sensitive and can detect finer details. The palm of your hand has many more receptors with smaller receptive fields, which allows it to distinguish between two closely spaced points better than the back of your hand. Skin areas with small receptive fields are better able to distinguish two similarly-spaced points. The palm has a smaller threshold for discerning between two points than the back, a result of the differences in the size of receptive fields.
If you were to perform a two-point discrimination test, you would notice that the minimum distance at which you can perceive two points as separate is much smaller on the palm than on the back of the hand. This increased sensitivity is due to the higher density of touch receptors in the palm, which is essential for tasks that require precise touch, such as gripping objects and feeling textures.
All of the noble gases, Group 18, have eight valence electrons in its outer shell (excluding helium which only has two). Which of these would represent the oxidation number of the noble gases such as xenon and argon?

Zero or +2
Explanation:
The noble gases already have a avplete outermost shell. They are the least reactive elements of earth?
Their normal oxidation number is zero but some have been shown to be reactive.
Answer:
Explanation:
Since oxidation number is derived from the number of electron in the outermost shell of an element and further more this oxidation number is a function of how much electron is needed by an element to achieve a duplet ( He) or octet configuration ( complete outer most shell which is the attributes of group 18 elements or noble gases) and they don't readily react with any compound.. Since Xenon and argon are noble gases , they will have their outer most shell completely feel hence their oxidation number will be zero (0)
A and B are mutually exclusive events. PA) = 0.50 and P(B) = 0.30. What is
PA or B)?
Answer:
P(A∪B)=0.8
Explanation:
Given that,
A and B are mutually exclusive events such that,
P(A)=0.5 and P(B)=0.3
We need to find P(A or B). It means we need to find P(A∪B). If two events are mutually exclusive, P(A∩B)=0. So,
P(A∪B)=P(A)+P(B)-P(A∩B)
Putting P(A) and P(B), we get :
P(A∪B)=0.5+0.3-0
P(A∪B)=0.8
So, the value of P(A or B) is 0.8

A 7310 kg space probe, moving nose-first toward Jupiter at 88.3 m/s relative to the Sun, fires its rocket engine, ejecting 54.0 kg of exhaust at a speed of 246 m/s relative to the space probe. What is the final velocity of the probe
Answer:
[tex]v_{1f} = 90.12m/s[/tex]
Explanation:
As we know that Probe along with rocket system is an isolated system
So here net force on this system must be zero
and we can use momentum conservation for this system
So we will have
[tex](m_1 + m_2)v_{i} = m_1v_{1f} + m_2v_{2f}[/tex]
here we know that
[tex]7310 \times 88.3 = (7310- 54)v_{1f} + 54(v_{1f} - 246)[/tex]
[tex]645473 = 7310\times v_{1f} - 13284\\658757 = 7310 \times v_{1f}[/tex]
so we have,
[tex]v_{1f} = 90.12m/s[/tex]
Answer:
Final velocity of Probe; V_f = 656.314 m/s
Explanation:
We are given;
Mass of space probe; m_i = 7310 kg
Initial velocity of probe ; v_i = 88.3 m/s
Mass of exhaust fuel; m = 54 kg
V_rel = 246 m/s
Mass of fuel; m_f = m_i - m = 7310 kg - 54kg = 7256 kg
From Rocket equation;
V_f - V_i = V_rel[In(m_i/m_f)]
Where V_f is final velocity of probe.
Thus, plugging in the relevant values to get ;
V_f - 88.3 = 246[In(7310/7256)]
V_f - 88.3 = 246 x 2.309
V_f - 88.3 = 568.014
Thus, V_f = 568.014 + 88.3 = 656.314 m/s

Sciencium-380 has a half-life of 3 days. If you started with a 100 gram sample, how much Sciencium-380 will remain after 9 days?
Answer: 12.5 grams will remain.
Explanation:
The half life time means that if we start with a quantity A of a given subtance/material, after the half time we will have half that quantity, or A/2.
We know that the half life of Sciencium-380 is 3 days.
So if we have 100 grams, after 3 days we will have 100/2 = 50 grams.
After other 3 days we will have 50/2 = 25 grams
After other 3 days we will have 25/2 = 12.5 grams.
So if we start with 100 grams, after 9 days we will have 12.5 grams.
Answer:
12.5 grams
Explanation:
Solution:-
- By definition, the half-life is the amount of time t that a substance of mass M to decay to half its its initial mass.
- We are given the mass of the Sciencium-380, M = 100 g
- The half-life for the radioactive isotope is, h = 3 days
- The amount of mass left after t = 9 days.
- We will first estimate the number of half-lives that have passed in te duration of t = 9 years.
- The number of half lives are:
n = t / h
n = 9 / 3
n = 3
- For every half life the mass is halved or mathematically the mass ( m ) of a substance remaining after " n " number of half lives can be expressed as:
m = M*0.5^n
- Plug in the given values and evaluate the mass ( m ) of the substance after n = 3 half lives.
m = 100*0.5^3
m = 12.5 grams.
Answer: We are left with 12.5 grams of Sciencium after 3 half lives have passed.

What is the speed of a particle whose kinetic energy is equal to its rest energy.
Answer:
The speed of the particle whose kinetic energy is equal to its rest energy is 4.242*10⁸m/s.
Explanation:
The rest energy is defined as the energy equal to the mass of the particle at rest in the inertial frame of reference equal to the rest mass time square of speed of light
E₀ = mc²
The kinetic energy is defined as the energy possessed by the particle due to its motion.
K.E =0.5mv².
where, m is the mass of the particle
c is the speed of light,
v is the velocity of the particle
It is given that Kinetic energy is equal to rest energy ie K.E = E₀
0.5mv² = mc²
v² = 2c²
v =√2c
= 1.414*3*10⁸
v =4.242 *10⁸ m/s
The speed of the particle whose kinetic energy is equal to its rest energy is 4.242*10⁸m/s.
The speed of a particle whose kinetic energy equals its rest energy would be a significant fraction of the speed of light, approximately 0.914c or 91.4% of the speed of light for an electron with kinetic energy 150% of its rest mass energy.
Explanation:The question asks about the relationship between kinetic energy and speed for a particle when the kinetic energy is equal to the particle's rest energy. Using the principles of relativity, we know that a particle's total energy is the sum of its rest mass energy and its kinetic energy. According to Einstein's theory of relativity, the kinetic energy (K) of a particle approaches infinity as its speed (v) approaches the speed of light (c). Therefore, for a particle to have its kinetic energy equal to its rest mass energy (E0), it must be traveling at a significant fraction of the speed of light.
Specifically, in the case of an electron with a rest mass energy of 0.511 MeV, if its kinetic energy is 150% of this value, calculations would show that the electron is traveling at a velocity approximately 0.914c, which is around 91.4% of the speed of light. This result is consistent with relativistic effects, which become significant as particles move at speeds approaching the ultimate speed limit, c, as stated by the theory of relativity.

What would happen if the voltage impressed across a circuit is held constant while the resistance doubles
Answer:
What would happen if the voltage impressed across a circuit is held constant while the resistance doubles.
The answer is:
A change will occur in the current which is, "The new current will be half the initial value."
Explanation:
Voltage, also called electromotive force, is the measure of specific potential energy between two locations in an electrical field.
V= IR
Where, V= Voltage
I= Current
R= Resistance
The greater the voltage in a circuit, the greater its ability to push more electrons and do work.
Voltage is measured in volts (V). Voltage is the difference in charge between two points, and can also be considered as the pressure that forces the charged electrons to flow in an electrical circuit.
Current is the rate at which charge is flowing. An electric current flows when electrons move through a conductor, such as a metal wire.
Resistance is a material's tendency to resist the flow of charge (current). Resistance is measured in ohms, and can be further explained as a measure of the opposition to current flow in an electrical circuit. Resistance is good because it protects humans from the harmful energy of electricity. Resistance, R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A).
Current is directly proportional to the voltage and inversely proportional to the resistance.
If voltage is increased, the current will also increase. The higher the resistance, the lower the current flow. The lower the resistance, the higher the current flow.
Doubling the voltage will cause the current to be doubled. Also, doubling the resistance will cause the current to be one-half the original value.
How does the law of inertia relate to how the planets in our solar system revolve around the sun?
Answer:
The law of inertia relates to revolution of planets round the sun due to constant motion of the planets round the sun.
Explanation:
Law of inertia states that a body at rest or uniform motion will continue to be at rest or uniform motion unless it is acted upon by an external force.
The gravitational force keeps the planets revolving round the sun in a uniform motion, this will continue till infinity unless equal and opposite force acts on our planets.
Therefore, the law of inertia relates to revolution of planets round the sun due to constant motion of the planets round the sun.
