A node is a place on a standing wave where the amplitude is the smallest. When a guitar string is plucked the nodes part of the standing wave is found at the fixed ends of the string.
What is a node?A node is a place on a standing wave where the amplitude is the smallest. The nodes at the ends of a vibrating guitar string, for example, are nodes.
The guitarist alters the effective length of the vibrating string and hence the note played by shifting the location of the terminal node through frets.

1. (I) If a particle undergoes SHM with amplitude 0.18 m,
what is the total distance it travels in one period?
Answer:
The total distance the particle travels in one period is approximately 1.131 m
Explanation:
The Simple Harmonic Motion (SHM) of an object can be conceptualized as the uniform circular motion of the object projected on an axis
Therefore, the amplitude of a SHM which is the largest displacement of the motion from its central or equilibrium position is equivalent to the radius of the circular motion
Therefore;
The amplitude of the SHM, a = 0.18 m = The radius of the equivalent circular motion, r
A period of SHM = The time it takes takes to complete one revolution
Therefore, the total distance traveled in one period = The length of 1 complete revolution = The circumference of the equivalent circle describing the SHM
The circumference of the equivalent circle describing the SHM, C = 2·π·r
By substituting the known value for the radius, 'r', we have;
C = 2·π·r = 2 × π × 0.18 m ≈ 1.131 m
Therefore, the total distance the particle travels in one period ≈ 1.131 m

Which is the first step in the process during the formation of molded fossils? A Sediment hardens into rock. B Sediment is eroded from rock. C Organisms are buried under sediment.
The first step in the process during the formation of molded fossils is that the sediment is eroded from rock. Thus, the correct option is B.
What is Fossil formation?Fossils are important as they provide important evidence for the evolution and the adaptation of plants and animal species to their environments. Fossil evidence helps in providing the record of how creatures have evolved and how this process can be represented through the help of a tree of life, showing that all the species are related to each other.
Four types of processes which contribute to the formation of a fossil include mineralization, carbonization, encrustation, and distillation. They occur once an organism has become fully trapped within the surrounding sediment, and it primarily depends up on the mineral composition of the silt and water.
Therefore, the correct option is B.

On February 12th I ran with my sisters. One positive behavior was that I did not go slow, and I kept with the pase. Another positive behavior was when the other person got tired or fell, the other two people helped them up. Some ways that I influenced the group was, I pushed the other people to do good and I also pushed them to not give up. Another way that I influenced the group was, I did not hold them down, like when they sped up, I sped up.
2.) How can participation in team sports improve your overall fitness?
It can improve my fitness by showing me that if they can do it, so can I and if I do not, it is not because I cannot, it is because I will not. Another way that it can improve my fitness is, if we start to slow down, we can tell each other to keep going and if we keep going, then our skill ability level will go up and that is how we can get more fit.

Un prisma rectangular con un volumen de 80 m^3 se sumerge hasta la mitad en agua, calcular la fuerza de empuje que recibe.(rho_(del agua)=1000 kg/m^3)
Answer:
400 kN
Explanation:
El principio de Arquímedes establece que, cuando un cuerpo está total o parcialmente sumergido en un fluido, experimenta un empuje hacia arriba que es igual al peso del fluido desplazado.
Dado que;
Volumen del bloque = 80m ^ 3
Densidad del agua = 1000 kg / m ^ 3
Empuje hacia arriba = 1/2 * 80 * 1000 * 10
Empuje hacia arriba = 400 kN
A snowball is rolling down a grassy hill. Determine what force is causing the object to slow down or speed up. Sketch a free-body diagram, including arrows, force values, and label be sure the label the forces appropriately.
Answer:
Rolling Friction (round object on a flat surface) Speeding up.
Explanation:
Gravity continually pulls something such as a table, roster, or person down from the hill. Thus, when you bounce, gravity makes you to arrive on the territory. Friction, however, doesn't pull something down. Friction, however, doesn't pull something downstairs. ... Also, friction always operates identically to the surface in connection because of the sliding movement.

how can changing the kinetic energy of an object cause energy to be transferred to or from the object
Kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. For the blue ball to move to the position of the green ball, energy must be given to the blue ball.

Two cars start moving from the same point on a rectilinear path at the same time, heading to the same destination 90 km away. The first travels at an average speed of 50 km/h and the second at 60 km/h. Deter- mine the time interval separating the arrival of the two cars to their destination.
Answer:
0.3 hour
Explanation:
From the question given above, the following data were obtained:
Distance travelled = 90 km
Speed of 1st car = 50 km/h
Speed of 2nd car = 60 km/h
Time interval separating the two cars =?
Next, we shall determine the time taken for each car to get to the destination. This can be obtained as follow:
For the 1st car:
Distance travelled (d) = 90 km
Speed of 1st car (S₁) = 50 km/h
Time (t₁) =?
Speed = Distance /time
S₁ = d/t₁
50 = 90 / t₁
Cross multiply
50 × t₁ = 90
Divide both side by 50
t₁ = 90 / 50
t₁ = 1.8 hours
For the 2nd car:
Distance travelled (d) = 90 km
Speed of 2nd car (S₂) = 60 km/h
Time (t₂) =?
Speed = Distance /time
S₂ = d/t₂
60 = 90 / t₂
Cross multiply
60 × t₂ = 90
Divide both side by 60
t₂ = 90 / 60
t₂ = 1.5 hours
Finally, we shall determine the time interval separating the arrival of the two cars. This can be obtained as follow:
Time for the 1st car (t₁) = 1.8 hours
Time for the 2nd (t₂) = 1.5 hours
Time interval separating the two cars (tₛ) =?
tₛ = t₁ – t₂
tₛ = 1.8 – 1.5
tₛ = 0.3 h
Thus, the interval separating the arrival of the two cars is 0.3 hour

A car is driving at a speed of 50 m/s. After 6 seconds he notices a wreck up ahead and slows down to 20 m/s. What is his acceleration
Answer:
the acceleration of the car is -5 m/s².
Explanation:
Given;
initial velocity of the car, u = 50 m/s
time of motion, t = 6 s
final velocity of the car, v = 20 m/s
The acceleration of the car is calculated as;
[tex]a = \frac{v-u}{t} \\\\a = \frac{20-50}{6} \\\\a = - 5 \ m/s^2[/tex]
Therefore, the acceleration of the car is -5 m/s².

A 2750 kg helicopter flies horizontally at constant speed. Air resistance creates a 7510 n backward force. What is the magnitude of the lift force created by the propellers
Answer:
Explanation:
Let lift force F be created by propellers at angle of Ф with the horizontal .
The vertical component of this force will balance the weight of helicopter and horizontal component will balance the air resistance .
F sinФ = mg = 2750 x 9.8 = 26950 N
F cosФ = 7510 N
Squaring and adding ,
F² = 26950² + 7510²
= 726302500 + 56400100
= 782702600
F = 27976.82 N .
_____ type of components is affected by the intensity of light.
Answer:
Explanation:
Some of the factors affecting intensity are: The energetic intensity of the source (the initial volume). The distance from the source (the volume at any point along the path). Any modifying elements in the light path (air, clouds, filters, reflectors, etc.) The factors affecting the intensity of light are diffraction.
Light has three properties: Wavelength, speed, and amplitude. The wavelength determines the type of light (color, etc.). Speed is determined by whether light passes through a vacuum or some material. The more photons emitted per unit time, the greater the intensity of the light. Directly, it is the power that determines the brightness of a bulb. That is why light bulbs have a power rating, i.e. a 60W bulb is enough to light a typical bedroom. But power is determined by the current and voltage which, in turn, is determined by the current.
