Well idk if this helps but the formula to solve acceleration is

a=F/m=(100kg)=1.0m/s 2

Rihanna can go from 0-60 miles per hour in 3.5 seconds. Calculate the acceleration.
Anton [14]

Answer:

7.66 m/s²

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 mph

Final velocity (v) = 60 mph

Time (t) = 3.5 s

Acceleration (a) =.?

Next, we shall convert mile per hour (mph) to metre per second (m/s). This can be obtained as follow:

Recall:

1 mph = 0.447 m/s

Initial velocity (u) = 0 mph

Initial velocity (u) = 0 × 0.447 = 0 m/s

Final velocity (v) = 60 mph

Final velocity (v) = 60 × 0.447 = 26.82 m/s.

Finally, we shall determine the acceleration of Rihanna as follow:

Initial velocity (u) = 0 m/s

Final velocity (v) = 26.82 m/s.

Time (t) = 3.5 s

Acceleration (a) =.?

a = (v – u) /t

a = (26.82 – 0) / 3.5

a = 26.82 / 3.5

a = 7.66 m/s²

Thus, the acceleration of Rihanna is 7.66 m/s²

¿ que es una onda mecánica y como es su gráfica? ¿qué es la amplitud y la frecuencia ?
Ainat [17]

Una onda mecánica es una onda que no es capaz de transmitir su energía a través del vacío. Las ondas mecánicas requieren un medio para transportar su energía de un lugar a otro. Una onda de sonido es un ejemplo de onda mecánica. Las ondas sonoras son incapaces de viajar a través del vacío. ¡su gráfico está debajo! La amplitud es un parámetro importante de las ondas y es el desplazamiento máximo de puntos en una onda. Dicho de otra manera, la amplitud es la distancia vertical entre un pico o un valle y el punto de equilibrio. La frecuencia es el número de ciclos de ondas que pasan por un punto por unidad de tiempo.

¡Espero que esto te ayude! Buena suerte y que tengas un gran día. :)

If element X has 39 protons, how many electrons does it have?
lara31 [8.8K]
Hi. There would be 39 electrons since in atoms there are the same amount of both protons and electrons. Good luck.
