Explanation:

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!)

Answer:

P = 10 Watts

Explanation:

Given that,

The voltage of a mobile charger, V = 5 V

Current, I = 2 A

We need to find the power of the charger. The formula for the electric power is given by:

P = VI

So,

[tex]P=5\ V\times 2\ A\\\\P=10\ W[/tex]

So, the power of the mobile charge is 10 watts.

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:

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

Answer: D. plant more trees where forests are cut down.

Explanation:

Deforestation has to do with the cutting down of trees. Cutting down the forest reduces the size of animal habitats, increases erosion, and results in an increase in the amount of carbon dioxide in the atmosphere.

Ok order to tackle the above, it is necessary that we should plant more trees where forests are cut down.

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.

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.

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.

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.

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

Answer:

outer core.....

The two layers of the earth where the actual temperature is hotter than the melting point is outer and inner core.

The 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.
