Answer:
The order of magnitude of the distance from the sun to Earth is 10⁸ km.
Explanation:
The order of magnitude of the distance from the sun to Earth can be calculated as follows:
![c = \frac{x}{t}](https://tex.z-dn.net/?f=%20c%20%3D%20%5Cfrac%7Bx%7D%7Bt%7D%20)
Where:
c: is the speed of light = 3x10⁸ m/s
t: is the time = 8 min
Hence, the distance is:
![x = c*t = 3 \cdot 10^{8} m/s*8 min*\frac{60 s}{1 min} = 1.44 \cdot 10^{11} m = 1.44 \cdot 10^{8} km](https://tex.z-dn.net/?f=%20x%20%3D%20c%2At%20%3D%203%20%5Ccdot%2010%5E%7B8%7D%20m%2Fs%2A8%20min%2A%5Cfrac%7B60%20s%7D%7B1%20min%7D%20%3D%201.44%20%5Ccdot%2010%5E%7B11%7D%20m%20%3D%201.44%20%5Ccdot%2010%5E%7B8%7D%20km%20)
Therefore, the order of magnitude of the distance from the sun to Earth is 10⁸ km.
I hope it helps you!
Answer:
the force exerted by the seat on the pilot is 10766.7 N
Explanation:
The computation of the force exerted by the seat on the pilot is as follows:
![F = Mg + \frac{MV^2}{R}\\\\= 70 \times 9.81 + \frac{70 \times 120^2}{100}\\\\= 10766.7 N](https://tex.z-dn.net/?f=F%20%3D%20Mg%20%2B%20%5Cfrac%7BMV%5E2%7D%7BR%7D%5C%5C%5C%5C%3D%2070%20%5Ctimes%209.81%20%20%2B%20%5Cfrac%7B70%20%5Ctimes%20120%5E2%7D%7B100%7D%5C%5C%5C%5C%3D%2010766.7%20N)
Hence, the force exerted by the seat on the pilot is 10766.7 N
The answer is:
V = d/t d = 86 km t = 1.3 hrs
V = 86 km/ 1.3 hrs
V = 66.15 km/ hrs

Explicación:
Usaremos la ecuación de movimiento para determinar la altura de la bola medida desde la parte superior del edificio.
Usando la ecuación para obtener la altura de caída
S = ut + 1 / 2gt²
u es la velocidad inicial = 25 m / s
g es la aceleración debida a la gravedad = 9,81 m / s²
t es el tiempo = 7 segundos
S es la altura de la caída
S = 25 (7) +1/2 (9,81) × 7²
S = 175 + 4,905 (49)
S = 175 + 240,345
S = 415,35 m
Esto significa que la pelota se elevó a 415,35 m de altura
