What measurement do we use to determine the amount of force used to move an object by a simple machine
Answer:
Newtons.
Explanation:
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
[tex] F = ma[/tex]
Where;
F represents force measured in Newton.
m represents the mass of an object measured in kilograms.
a represents acceleration measured in meter per seconds square.
Newtons is a measurement we use to determine the amount of force used to move an object by a simple machine. It is the International System of Units (SI) used to measure force and has a symbol of N.
Basically, it was named after Sir Isaac Newton based on his fundamental works in the field of mechanics (motions).

What is a main difference between a mixture and a pure substance?
illl give you 100 points!!!
A mixture is only a liquid, but a pure substance can be in any state.
A mixture looks the same throughout, but a pure substance does not.
A mixture can vary in composition, but a pure substance has a set composition.
A mixture can be made up of a single compound, but a pure substance cannot.
Answer:
C
Explanation:
A-false, mixtures can be solids too.
B-false, pure substances will have a constant appearance
C-true, a mixture has two or more composition, but the pure substance has a constant composition
D-false, mixtures have more than 1 compounds as I said before
A mixture can vary in composition, but a pure substance has a set composition. Thus, a pure substance is homogeneous always.
What is a mixture?A mixture is the combination of two or more individual components which are mixed physically or chemically. Mixtures can be homogenous or heterogenous.
A pure substance is a fixed composition containing its own particles only. For example, water, fruits, pure metals etc.Thus, pure substances are always homogeneous. In the case of mixtures, the composition is not definite.
Homogeneous mixtures appears to be one phase whereas, a heterogenous mixture shows phase separation. The components of a mixture can be separated physically.

We know we have the formula
wavelength = speed / frequency
4 = 332 / frequency
frequency = 332/4
Therefore frequency is 83 Hertz .
A mosquito can fly with a speed of 1.10 m/s with respect to the air. Suppose a mosquito flies east at this speed across a swamp. The mosquito is flying into a breeze that has a velocity of 1.4 m/s with respect to Earth and moves in the direction of 35 west of south. What is the mosquito's speed with respect to the Earth?
Answer:
The velocity of Mosquito with respect to earth will be 0.302m/s
Explanation:
V(ma) = 1.10 m/s, east Velocity of mosquito with respect to air
V(ae) = 1.4 m/s at 35° Velocity of air with respect to Earth in west of south direction.
Velocity of Mosquito with respect to earth will be
V(me) = V(ma) + V(ae)
We need to find the mosquito’s speed with respect to Earth in the x direction.
V(x, me) = V(x, ma) + V(x, ae) = V(ma) + V(ae)(cos theta(ae) )
Angle (ae) = –90.0° − 35°=−125°
V(x, me) = 1.10 + (1.4)Cos(-125)
= 1.10 + 1.4(-0.57)
= 1.10 -0.798
= 0.302
So the velocity of Mosquito with respect to earth will be 0.302m/s
What type of sonar causes loud noises in the water?
Answer:
low frequencies
Explanation:
The type of sonar that causes loud noises in the water is known as active sonar.
Active sonar is a system that emits sound waves into the water and listens for their reflections to detect objects and measure distances. It works by sending out a pulse of sound, which travels through the water and reflects off objects such as submarines, ships, or marine life.
The reflected sound, or echo, is then received by the sonar system's hydrophone, allowing it to analyze the data and provide information about the surrounding environment.
While active sonar is effective for detecting objects and underwater features, it can also produce loud noises that may have various effects on marine life.
The loud sound pulses can potentially disturb or harm marine animals, particularly marine mammals like whales and dolphins, which rely heavily on sound for communication and navigation. The use of active sonar has been a topic of environmental concern, and efforts are made to minimize its impact on marine ecosystems through regulations and responsible use.
Hence, The type of sonar that causes loud noises in the water is known as active sonar.

Please define the prefixes hyper-, hypo-, & iso- AND describe a solution that is hypertonic, hypotonic, & isotonic as well as compare how a living cell reacts when placed in a solution of each of the 3 types.
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

None of these is correct.
Answer:
radius of a circle is measured by an instrument, so it is the independent variable
Explanation:
The independent variable corresponds to the magnitude controlled by the experimenter and in general can be measured by an instrument.
The dependent variable is the variable used to perform the calculations, obtained from a mathematical transformation of the independent variable.
The radius of a circle is measured by an instrument, so it is the independent variable and the area is calculated by
A = π r²
Therefore the area corresponds to the dependent variable
Un automóvil se mueve a velocidad constante v = 60 [km/h]. Si el tiempo de reacción del conductor al ver la luz roja de una intersección es de 0.5 [s], y ´este desacelera a razón de 40 [m/s2 ] ¿Qué distancia recorre el automóvil desde el instante en que el conductor nota la se˜nal hasta detenerse por completo? Entiéndase por tiempo de reacción, el intervalo de tiempo transcurrido entre el instante en que se percibe la señal y el instante en que se lleva a cabo la acción (instante en que el conductor activa el sistema de frenado).
Answer:
El automóvil recorre una distancia de 11.806 metros antes de deternerse por completo.
Explanation:
De acuerdo con el enunciado, el conductor nota la luz roja, empieza a decelerar 0.5 segundos después y decelera hasta detenerse. La distancia total recorrida por el automóvil desde el instante en que el conductor nota la luz roja ([tex]\Delta s_{T}[/tex]), medida en metros:
[tex]\Delta s_{T} = \Delta s_{1}+\Delta s_{2}[/tex] (1)
Donde:
[tex]\Delta s_{1}[/tex] - Distancia recorrida a velocidad constante, medida en metros.
[tex]\Delta s_{2}[/tex] - Distancia recorrida hasta alcanzar el reposo, medida en metros.
Si suponemos que la segunda etapa describe un movimiento uniformemente acelerado, entonces la distancia recorrida total que representada por la siguiente fórmula:
[tex]\Delta s_{T} = v_{o}\cdot \Delta t_{o} + \frac{v_{f}^{2}-v_{o}^{2}}{2\cdot a}[/tex] (2)
Donde:
[tex]v_{o}[/tex] - Velocidad inicial del automóvil, medida en metros por segundo.
[tex]v_{f}[/tex] - Velocidad final del automóvil, medida en metros por segundo.
[tex]\Delta t_{o}[/tex] - Tiempo de reacción del conductor, medido en segundo.
[tex]a[/tex] - Aceleración, medida en metros por segundo al cuadrado.
Si conocemos que [tex]v_{o} = 16.667\,\frac{m}{s}[/tex], [tex]v_{f} = 0\,\frac{m}{s}[/tex], [tex]\Delta t_{o} = 0.5\,s[/tex] y [tex]a = -40\,\frac{m}{s^{2}}[/tex], entonces la distancia recorrida total es:
[tex]\Delta s_{T} = \left(16.667\,\frac{m}{s} \right)\cdot (0.5\,s)+\frac{\left(0\,\frac{m}{s} \right)^{2}-\left(16.667\,\frac{m}{s}\right)^{2}}{2\cdot \left(-40\,\frac{m}{s^{2}} \right)}[/tex]
[tex]\Delta s_{T} = 11.806\,m[/tex]
El automóvil recorre una distancia de 11.806 metros antes de deternerse por completo.

what must be true if a waves wavelength is short ?
Answer: So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. ... That means that longer wavelengths have a lower frequency. Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!
If the wavelength of a wave is short. It is true that the wave will have a lower frequency. A longer wavelength denotes a lower frequency.
What is a wave?A wave is a phenomenon that flows across a material medium without leaving any lasting mark.
Frequency is defined as the number of cycles per second. The time to make one complete cycle is the frequency and the distance between successive crests of a wave is the wavelength.
Thus, a shorter wavelength of a light wave signifies a greater frequency since one cycle may pass in a shorter amount of time. Longer wavelengths have a lower frequency.
Hence a longer wavelength denotes a lower frequency, whereas a shorter wavelength denotes a higher frequency.
