Yes, a top speed of 18.6 mph (8.31 m/s) for a DC Scooter is scientifically possible. Electric scooters can achieve high speeds depending on their motor power, battery capacity, and design.
The reported speed falls within the range of what is achievable for many electric scooters available on the market today. Electric scooters typically use electric motors to generate propulsion. These motors can provide high torque and power, allowing the scooter to reach higher speeds. Additionally, advancements in battery technology have increased the energy density and capacity of scooter batteries, enabling them to sustain higher speeds for longer durations.While specific models may have varying top speeds, 18.6 mph is within the realm of possibility for electric scooters, and it aligns with what is commonly offered by manufacturers.

disordered eating is often __________.
A.
an eating disorder that affects numerous teens
B.
caused by eating irregularly over short periods
C.
a precursor for developing a disorder, but not a disorder on its own
Answer:
B) caused by eating irregularly over short periods
Explanation:
Disordered eating refers to a range of irregular and unhealthy eating behaviors and attitudes toward food. Disordered eating is often C. a precursor for developing a disorder, but not a disorder on its own
Disordered eating refers to a range of irregular eating behaviors and attitudes towards food that may not meet the full diagnostic criteria for an eating disorder but still involve disturbances in eating patterns, body image, and weight. It can include behaviors such as restrictive eating, binge eating, purging, or excessive exercise.
While disordered eating shares similarities with eating disorders, it is considered a precursor or warning sign that someone may be at risk of developing a diagnosable eating disorder, such as anorexia nervosa, bulimia nervosa, or binge eating disorder. Disordered eating patterns can often progress and become more severe if left untreated, potentially leading to the development of an eating disorder.
Thereofre, disordered eating is often C. a precursor for developing a disorder, but not a disorder on its own.

El Burj Khalifa es la torre más alta de Dubai y mide 821 m. Si se deja caer una moneda desde lo alto de la torre, ¿cuál es la magnitud de la velocidad con la que choca con el suelo?
Answer:
Vf = 126,85 m/s
Explanation:
En este caso, vamos a asumir que la velocidad inicial de la moneda cuando se deja caer es cero, puesto que no nos lo indican. Al ser la velocidad inicial cero, lo unico que influye en la velocidad de la moneda es la gravedad y la altura, por ende, la siguiente formula nos ayudará a calcularla:
Vf² = Vo² - 2gh (1)
Pero como la velocidad inicial es cero, y si también asumimos que la dirección de bajada será nuestro eje positivo, entonces:
Vf² = 2gh (2)
Ahora solo nos queda, reemplazar los valores de altura que es 821 m, y la aceleración de gravedad que es 9.8 m/s² y resolvemos la velocidad:
Vf² = 2 * 9,8 * 821
Vf = √16091,6
Vf = 126,85 m/sEsta debería ser la velocidad con que llega al suelo.
Exitos
La magnitud de la velocidad con la que choca con el suelo es aproximadamente 126.898 metros por segundo.
Si despreciamos los efectos de la viscosidad del aire y la aceleración de Coriolis, entonces el movimiento de la moneda se describe por el movimiento de caída libre, es decir, un movimiento uniforme acelerado debido a la gravedad terrestre. La velocidad final de la moneda es determinada por la siguiente ecuación cinemática:
[tex]v = \sqrt{v_{o}^{2}+2\cdot a\cdot h}[/tex] (1)
Donde:
[tex]v_{o}[/tex] - Velocidad inicial, en metros por segundo.[tex]a[/tex] - Aceleración, en metros por segundo al cuadrado.[tex]h[/tex] - Altura, en metros.[tex]v[/tex] - Velocidad final, en metros por segundo.Si sabemos que [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]a = 9.807\,\frac{m}{s^{2}}[/tex] y [tex]h = 821\,m[/tex], entonces la velocidad final de la moneda es:
[tex]v = \sqrt{\left(0\,\frac{m}{s} \right)^{2}+2\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (821\,m)}[/tex]
[tex]v\approx 126.898\,\frac{m}{s}[/tex]
La magnitud de la velocidad con la que choca con el suelo es aproximadamente 126.898 metros por segundo.

Storm water picks up pollutants off of these types of surfaces because they are not able to absorb rainfall
Answer:
True.
Explanation:
Rainwater cannot be absorbed by some surfaces. This prevents these water from infiltrating and traveling through this area, taking with it the potential pollutants that it may present, such as sediment, remains of fertilizers, bacteria, animal waste, pesticides, metals, among others. This causes a process that we can call Diffuse Pollution and can cover large areas and even bodies of water.

Look at the equation below. What units are used for W? Give the full name, not the symbol.
Enter your answer
W = m x g
Answer:
the watt is a unit of power
The symbol W denotes the work done and m is the mass and g is the acceleration due to gravity. If m is in Kg and g has a unit of m/s². Then the unit Kg m/s² is equal to one joule J. That is the unit of work done.
What is work done?Work done in physics is the dot product of force and displacement. Work done of one joule is equal to the force of one newton, exerted by an object of mass m and acceleration a.
Thus we have F = Ma.
If the acceleration is replaced by acceleration due to gravity g, then force of one Newton is mg, that is the product of mass and acceleration. Force is an external agent act on a body to change its state from rest or motion.
If the force applied causes a displacement of the object, then a work is done on the body. Let the mass is taken in Kg and acceleration due to gravity is in m/s², then one newton is Kg m/s² is equal to one joule J. Hence, W has the unit of Kg m/s² or J.

A box of books weighing 315 N is shoved across the floor by a force of 477 N exerted downward at an angle of 35° below the horizontal. If the coefficient of kinetic friction between the box and the floor is 0.58, how long does it take to move the box 4.20 m starting from rest?
Answer:
It takes 1.14 s to move the box 4.20 m.
Explanation:
Using Newton's second law we have:
[tex]Fcos(35)-F_{f}=ma[/tex]
[tex]Fcos(35)-\mu mg=ma[/tex]
F is the force exerted and m the mass of the books
[tex]Fcos(35)-\mu mg=ma[/tex]
[tex]477cos(35)-(0.58*315)=\frac{315}{9.81}a[/tex]
So, the books accelerate at:
[tex]a=6.48\: m/s^{2}[/tex]
We know that the initial velocity is zero, so using the kinematic position equation, we have:
[tex]x=\frac{1}{2}at^{2}[/tex]
So, we just need to solve the equation for t.
[tex]4.2=\frac{1}{2}6.48t^{2}[/tex]
[tex]t=\sqrt{\frac{2*4.2}{6.48}}[/tex]
Taking the positive value of t:
[tex]t=1.14\: s[/tex]
Therefore, it takes 1.14 s to move the box 4.20 m.

A shopping bag can provide a force of 65 N before breaking. A shopper puts 5 kg of groceries in the bag. If the shopper tries to lift the bag with an upward acceleration of 2 m/s/s, will the bag break?
Answer:
the bag DOES NOT BREAK, F = 59 N
Explanation:
For this exercise, let's use Newton's second law, let's set a reference frame with the positive direction up
F -W = m a
the mass of the groceries is m = 5 kg, the weight is
W = m g
indicate the acceleration a = 2 m / s², let's find the force
F = mg + ma
F = m (g + a)
let's calculate
F = 5 (9.8 + 2)
F = 59 N
F <65 N
as the force with which it pulls the bag less than the breaking force the bag DOES NOT BREAK
