Physics
1 answer:
Serjik [45]3 years ago
6 0

Answer:

A

Explanation:

The roller coaster is stationary so the kinetic energy would be zero, but it is at the top of ramp so the potential energy would be high as its gravitational  so it would have to be A

Suppose that you are standing on a train accelerating at 0.20g. What minimum coefficient of static friction must exist between y
Ilia_Sergeevich [38]
Acceleration = (0.2 x g) = 1.96m/sec^2. 
<span>Accelerating force on 1kg. = (ma) = 1.96N. </span>
<span>1kg. has a weight (normal force) of 9.8N. </span>
<span>Coefficient µ = 1.96/9.8 = 0.2 minimum. </span>

<span>Coefficient is a ratio, so holds true for any value of mass to find accelerating force acting. </span>
<span>e.g. 75kg = (75 x g) = 735N. </span>
<span>Accelerating force = (735 x 0.2) = 147N</span>

Damm [24]

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 (v), medida en metros por segundo, queda traducida en la siguiente fórmula:

v = \sqrt{\frac{\gamma \cdot R_{u}\cdot T}{M} } (1)

Donde:

\gamma - Coeficiente de dilatación térmica, sin unidad.

R_{u} - Coeficiente universal de los gases ideales, medido en kilogramo-metros cuadrados por mol-Kelvin-segundo cuadrado.

T - Temperatura, medida en Kelvin.

M - 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)
