The ________________of an element is the average mass of the element’s ____________________.
Answer:
The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.(I hope this helps!)

THE RIGHT ANSWER WILL RECEIVE A BRAINLESS AND POINTS AND THANKS!!! THE RIGHT ANSWER WILL RECEIVE A BRAINLESS AND POINTS AND THANKS!!! What is the fundamental frequency of a mandolin string that is 42.0 cm long when the speed of waves of the string is 329 m/s? with working outs
Answer:
[tex]f_{o}[/tex] = 391.67 Hz
Explanation:
The sound of lowest frequency which is produced by a vibrating sting is called its fundamental frequency ([tex]f_{o}[/tex]).
The For a vibrating string, the fundamental frequency ([tex]f_{o}[/tex]) can be determined by:
[tex]f_{o}[/tex] = [tex]\frac{v}{2L}[/tex]
Where v is the speed of waves of the string, and L is the length of the string.
L = 42.0 cm = 0.42 m
v = 329 m/s
[tex]f_{o}[/tex] = [tex]\frac{329}{2*0.42}[/tex]
= [tex]\frac{329}{0.84}[/tex]
[tex]f_{o}[/tex] = 391.6667 Hz
The fundamental frequency of the string is 391.67 Hz.

you are on a walk moving at 3m/s forward what would happen i you stepped off onto the floor? what if you stepped onto another walkaway moving with the same velocity?
Answer:
1) The person ma tend to fall
2) The person will remain upright
Explanation:
1) According to Newton's first law of motion, an object will continue in its state of rest or maintain its uniform motion on a straight line unless acted on by a force
Therefore, when a person steps off onto the floor from a walkway moving at 3 m/s, the friction between the floor and the person's feet prevents the forward motion of the feet, however the person's upper body will tend to continue with the forward motion, and the person may tend to tilt and fall over
2) If the person steps onto another walkway moving with the same velocity, the initial velocity of all parts of the person's body is maintained, such that the person will continue in his uniform motion without experiencing any force and therefore, the person will remain upright

. Si mi mejor amigo vive a 100 metros de mi casa (una cuadra aproximadamente) y sabe qué cuando pongo una canción determinada es porque me voy a poner a bailar ¿Cuándo escuchará más rápido la música mi amigo en un día que la temperatura este en 27°C o en 36°C?
Answer:
Nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)
Explanation:
Supongase que el aire se comporta como un gas ideal y que experimenta un proceso adiabático, entonces la velocidad del sonido ([tex]v[/tex]), medida en metros por segundo, queda traducida en la siguiente fórmula:
[tex]v = \sqrt{\frac{\gamma \cdot R_{u}\cdot T}{M} }[/tex] (1)
Donde:
[tex]\gamma[/tex] - Coeficiente de dilatación térmica, sin unidad.
[tex]R_{u}[/tex] - Coeficiente universal de los gases ideales, medido en kilogramo-metros cuadrados por mol-Kelvin-segundo cuadrado.
[tex]T[/tex] - Temperatura, medida en Kelvin.
[tex]M[/tex] - Masa molar, medida en kilogramos por mol.
Como se puede ver, la velocidad del sonido es directamente proporcional a la raíz cuadrada de la temperatura. Por tanto, nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)

Answer:
The substance is increasing
Hope this helps!
In AB and BC of the graph, the substance is first under the constant temperature condition then under section BC the linear increment in the temperature with the time.
What is a graph ?A graph is a pattern consisting of a collection of elements, some of which are connected in some way.
In the isothermal process, the change in the temperature is zero. While if temperature is increasing along the time, a linear relationship is found.
Hence, in AB and BC section of the graph, the substance is first under the constant temperature condition then under section BC the linear increment in the temperature with the time.

A stalled car is pushed with a force of 342 N from rest. How far does the car travel in 12 seconds if its mass is 989 kg?
Answer:
Roughly 25 meters
Explanation:
Use the formula D=1/2*a*t^2 where d=distance, a=acceleration, and t=time
Plug in all the variables we know...
D=1/2*a*12^2
in order to solve for acceleration, we use the formula F=ma where F=force, m=mass, and a=acceleration.
Plug in known variables,
342N=989kg*a
solve for a and we get...
342N/989kg=a
Now that we know the acceleration, we can plug that into our original equation and solve for distance.
D=1/2*342N/989kg*12s^2
Simplify,
D=72s^2*342N/989kg
D=72s^2*342kgm/s^2/989kg
D=72s^2*342m/s^2/989
D=72*342m/989
D=24624/989 meters, or 24.898meters which rounds up to 25.

A girl walks 5km due north,then in the direction of 60° of northeast towards her final destination.If the magnitude of her resultant displacement is 8km,how far she must have travelled in north east direction?
Answer:
4.2 km
Explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, scalene triangle, equilateral triangle and right angled triangle.
Sine rule states that for a triangle with angles A,B and C and corresponding opposite sides a, b, and c, the following formula holds:
[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
Let the starting point be A, hence the side opposite to the angle = a = distance travelled in north east direction.
Let the point of 60° of northeast be B = 90° + (90° - 60°) = 120°, hence the side opposite to the angle = b = resultant displacement = 8 km.
Let C be the endpoint, hence the side opposite to the angle = c = distance travelled north = 5 km
Using sine rule:
[tex]\frac{b}{sin(B)}=\frac{c}{sin(C)} \\\\\frac{8}{sin(120)}=\frac{5}{sin(C)} \\\\sin(C)=\frac{5*sin(120)}{8} =0.5412\\\\C=sin^{-1}(0.5412)=32.8^o\\\\[/tex]
∠A + ∠B + ∠C = 180° (sum of angle in a triangle)
∠A + 120 + 32.8 = 180
∠A = 27.2°
[tex]\frac{b}{sin(B)}=\frac{a}{sin(A)} \\\\\frac{8}{sin(120)}=\frac{a}{sin(27.2)} \\\\a=\frac{8*sin(27.2)}{sin(120)} \\\\a=4.2\ km[/tex]
Therefore she travelled 4.2 km in the north east direction
Identify the two layers of the earth in which the actual temperature is hotter than the melting point
Answer:
outer core.....
The two layers of the earth where the actual temperature is hotter than the melting point is outer and inner core.
Layers of the earthThe Earth is separated into four layers.
These layers are the crust, the mantle, the outer core, and the inner core.
The hottest layer is the inside of the Earth.
The inner core is more hot than the outer core.
The force on the inner core is higher.
Therefore we can conclude that both the inside layers of the earth are hotter than the melting point.
