No , frequency of a wave is not distance between waves, it is called wavelength.
Frequency is the number of waves that pass a particular point in a given period of time. It is typically measured in Hertz (Hz), which is the number of waves per second. Wavelength, on the other hand, is the distance between two consecutive crests or troughs of a wave. It is typically measured in meters (m). So frequency and wavelength are related, but they are not the same thing. Frequency is a measure of the number of waves, while wavelength is a measure of the distance between waves.

Explanation:
A 10 kg firework is shot in the air at 75 m/s. What is the momentum of the firework?
Answer:
Momentum = 750 Kgm/s
Explanation:
Given the following data;
Mass = 10 kg
Velocity = 75 m/s
To find the momentum;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
Substituting into the formula, we have;
Momentum = 10 * 75
Momentum = 750 Kgm/s
● Describe what Neptune needs to sustain life.
● Describe the current conditions of Neptune. How is it there?
● What is the final recommendation for the humans living on Neptune? Explain.
Answer:
1)the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That's very cold, and there's no way liquid water could exist.
2)Neptune has the wildest and strangest weather in the entire Solar System. It has huge storms with extremely high winds. Its atmosphere has dark spots which come and go, and bright cirrus-like clouds which change rapidly. Neptune has an average temperature of -353 Fahrenheit (-214 Celsius).

Can I have an anime weirdo friend that's a girl pwease cuz guys are mean and don't understand. I'm a 16 yo guy
Answer:
Girls, we found one.
The "uwu pwease pwotect me, waifu" 'nice guy' that tries convincing naive girls to send inappropriate pictures within 2 hours of knowing them because he "in love" them.
The reality of the situation is the dude is very desperate and wants to project their anime girl fantasies onto a girl that pities them because "gwuys are mwean" to them.
Step-by-step explanation:
You're 16, kid. Two years until you're 18. Just say you want a weeb girl/friend. no need to try and draw pity from little girls and use that to manipulate them. If you said this when you were 12, it would be excusable. But you're 16. If you want to attract girls, don't use pity. Or try to type words in a cutesy manner, that's just very unattractive and makes you seem desperate.

A man's higher initial acceleration means that a man can outrun a horse over a very short race. A simple - but plausible - model for a sprint by a man and a horse uses the following assumptions: The man accelerates at 6.0 m/s2for 1.8 s and then runs at a constant speed. A horse accelerates at a more modest 5.0 m/s2 but continues accelerating for 4.8 s and then continues at a constant speed. A man and a horse are competing in a 200 m race. The man is given a 100 m head start, so he begins 100 mfrom the finish line.
How much time does it take the man to finish the race? The horse? Who wins?
Answer:
t_man = 10.16 s, t_horse = 10.73 s, the winner is the man
Explanation:
To solve this problem we are going to find the time of each one separately.
Man we look for distance and time during acceleration
x₁ = v₀ t₁ + ½ a₁ t₁²
as it comes out of rest its initial velocity is zero
x₁ = ½ a₁ t₁²
x₁ = ½ 6.0 1.8²
x₁ = 9.72 m
at this point its speed is
v₁ = v₀ + a t
v₁ = 0 + 6 1.8
v₁ = 10.8 m / s
From here on it continues at constant speed, the distance that the man needs to travel from the point where the man leaves at 100m is
x₂ = 100 - x₁
x₂ = 100- 9.72
x₂ = 90.28 m
the time for this part is
v₁ = x₂ / t₂
t₂ = x₂ / v₂
t₂ = 90.28 / 10.8
t₂ = 8.36 s
the total time for the man is
t_man = t₁ + t₂
t _man = 1.8 + 8.36
t_man = 10.16 s
We repeat the calculation for the horse
distance traveled during the acceleration period
x₃ = v₀ t + ½ a₂ t₃²
as part of rest its initial velocity is zero
x₃ = ½ a₂ t₃²
x₃ = ½ 5.0 4.8²
x₃ = 57.6 m
the velocity at this point is
v₃ = v₀ + a₂ t₃
v₃ = 0 + 5 4.8
v₃ = 24 m / s
the rest of the route is at constant speed, the remaining distance
x₄ = 200 - x₃
x₄ = 200 - 57.6
x₄ = 142.4 m
the time to go through it is
t₄ = x₄ / v₃
t₄ = 142.4 / 24
t₄ = 5.93 s
the total time for the horse is
t_horse = t₃ + t₄
t_horse = 4.8 + 5.93
t_horse = 10.73 s
when we compare the times we see that the man arrives a little before the horse, the winner is the man

A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall, and the other end is connected to a movable object. The spring and object are compressed by 0.065 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 11.3 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.048 m relative to its unstrained length
Answer:
Explanation:
Given that:
angular frequency = 11.3 rad/s
Spring constant (k) = [tex]= \omega^2 \times m[/tex]
k = (11.3)² m
k = 127.7 m
where;
[tex]x_1[/tex] = 0.065 m
[tex]x_2[/tex] = 0.048 m
According to the conservation of energies;
[tex]E_1=E_2[/tex]
∴
[tex]\Big(\dfrac{1}{2} \Big) kx_1^2 =\Big(\dfrac{1}{2} \Big) mv_2^2 + \Big(\dfrac{1}{2} \Big) kx_2^2[/tex]
[tex]kx_1^2 = mv_2^2 + kx_2^2[/tex]
[tex](127.7 \ m) \times 0.065^2 = v_2^2 + (127.7 \ m) \times 0.048^2[/tex]
[tex]0.5395325 = v_2^2 +0.2942208 \\ \\ 0.5395325 - 0.2942208 = v_2^2 \\ \\ v_2^2 = 0.2453117 \\ \\ v_2 = \sqrt{0.2453117} \\ \\ \mathbf{ v_2 \simeq0.50 \ m/s}[/tex]

Answer:
[tex]0.00074m[/tex] [tex]=[/tex] [tex]7.4*10^{-4}m[/tex]
Explanation:
Given
[tex]0.00074m[/tex]
Required
Express as scientific notation
The scientific notation of a number is: [tex]a * 10^{b}[/tex]
Where [tex]1 \le a \le 9[/tex]
This implies that:
[tex]0.00074m = 7.4 * 10^b[/tex]
Next, is to determine the value of b.
Count the number of point to move from the current point location to 7.4.
If the point moves backward, b will be negative, else b will be positive.
So:
[tex]0.00074m[/tex] [tex]b=-4[/tex]
Hence:
[tex]0.00074m[/tex] [tex]=[/tex] [tex]7.4*10^{-4}m[/tex]

Cold water flows to the solar panels at 15°C. During the day, the panels supply 3.8 kg of hot water
at 65°C every hour.
(a) Calculate the average energy that the solar panels deliver to the water in one hour.
Specific heat capacity of water = 4200 J/(kg°C).
Answer:
The average energy that the solar panel delivers to the water in one hour is 798,000 Joules
Explanation:
The given parameters are;
The temperature of the water that flows to the solar panels, T₁ = 15°
The mass of the hot water the panel supplies during the day, m = 3.5 kg
The temperature of the hot water supplied by the panel, T₂ = 65 °C
The heat capacity of the water, c = 4,200 J/(kg·°C)
The heat delivered to the solar panels in one hour, ΔQ, is given by the following formula
ΔQ = m·c·ΔT
m = 3.8 kg, c = 4,200 J/(kg·°C), and ΔT = T₂ - T₁ = 65 °C - 15 °C = 50 °C
∴ ΔQ = 3.8 kg × 4,200 J/(kg·°C) × 50°C = 798,000 joules
∴ΔQ = 798,000 joules
The average energy that the solar panel delivers to the water in one hour, ΔQ = 798,000 joules.

Your little cousin loves ice cream bars. You buy him one and he starts to lick it. As you sit down on a park bench, he drops
the bar on the seat of the bench. You pick up the bar to throw it away, but he starts to cry, so you shrug and give it back to
him. Will he definitely get sick?
Answer:
nop
Explanation:
It is not certain whether the child will get sick from eating the ice cream bar that was dropped on the bench.
What is contamination?Contamination refers to the presence or introduction of harmful substances or organisms into a material, environment, or food source.
There is a possibility that the ice cream bar could have picked up bacteria or other contaminants from the bench that could make the child sick. However, the risk of illness depends on a number of factors, including the cleanliness of the bench, the length of time the ice cream was in contact with the bench, and the overall health of the child's immune system.
To reduce the risk of illness, it is important to wash hands and surfaces frequently, especially when handling food. If possible, it is best to discard food that has come into contact with potentially contaminated surfaces to prevent the spread of illness. However, if the child has already eaten the ice cream bar and does become sick, it is important to monitor their symptoms and seek medical attention if necessary.

Un ciclista recorre 10 km en 2 h.Calcula su velocidad media en km/h.¿cuantos metros recorre cada segundo
Answer:
La velocidad media es 5 [tex]\frac{km}{h}[/tex], que equivale a 1.389 [tex]\frac{m}{s}[/tex]
Explanation:
La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello.
La velocidad media relaciona el cambio de la posición con el tiempo empleado en efectuar dicho cambio. Por lo que se calcula como la distancia recorrida por un objeto dividido por el tiempo transcurrido:
[tex]velocidad=\frac{distancia}{tiempo}[/tex]
En este caso:
distancia= 10 km= 10,000 m (siendo 1 km= 1,000 m)tiempo= 2 h= 7,200 s (siendo 1 h= 3,600 s)Entonces, reemplazando en la definición de velocidad media:
[tex]velocidad=\frac{10 km}{2 h}= \frac{10,000 m}{7,200 s}[/tex]
Resolviendo se obtiene:
[tex]velocidad=5 \frac{km}{h}= 1.389\frac{m}{s}[/tex]
La velocidad media es 5 [tex]\frac{km}{h}[/tex], que equivale a 1.389 [tex]\frac{m}{s}[/tex]
Astronomers were at first surprised to find complicated molecules in the interstellar medium. They thought ultra-violet light from stars would break apart such molecules. What protects the molecules we observe from being broken apart?A. such molecules form in cells, and there is a protective membrane around each cellB. such molecules always form inside stars; the stars outer layers protect themC. such molecules form in clouds that contain significant amounts of dust, and the dust in the cloud protects them from ultra-violet raysD. such molecules form only in the regions that are already millions of degrees hot and thus can’t be affected by ultra-violet raysE. you can’t fool me; the seeming discovery of complex molecules out there was a mistake, and astronomers now realize there are no molecules out there.
Answer:
The objects that protects the molecules observed from being broken apart is option C;
Such molecules form in clouds that contain significant amount of dust, and the dust in the cloud protects them from ultra-violet rays
Explanation:
The existence of high energy cosmic and ultraviolet radiation is capable of breaking molecules present within translucent clouds in the interstellar medium.
However, when the light is passed through translucent clouds that are several light years thick or through non-transparent clouds interactions with the gases and dusts result in changes in the starlight that reaches a certain distance such as Earth
Therefore, the formation and presence of such molecules in clouds that are made up of dust serves to protect them from being broken by the high energy ultraviolet rays from the stars.
