Ō 21:49 Період обертання тiла становить 30 хв. Визначте радіус орбіти, якщо швидкість РУХУ ПО КОЛУ дорівнює 314 м/с. п =3,14. Вiдповiдь подайте в км. Ⓒ7/12 KM. Зберегти і перейти далі​

Answer 1

Відповідь:

Пояснення:

дано

T=1800c

v=314m/c

п=3.14

R-?

v=2пR/T

R=vT/2п=314*1800/2*3.14=90000м=90км

Answer 2

To find the radius of the orbit, we can use the formula for the period of rotation of a body in circular motion:

T = 2πr/v

Where: - T is the period of rotation (given as 30 minutes, which is equal to 0.5 hours) - r is the radius of the orbit (what we need to find) - v is the velocity of the body in circular motion (given as 314 m/s)

Let's substitute the given values into the formula and solve for r:

0.5 = 2πr/314

To find r, we can rearrange the equation:

r = (0.5 * 314) / (2π)

Now, let's calculate the value of r using the given values:

r = (0.5 * 314) / (2 * 3.14)
r = 157 / 6.28
r ≈ 24.92 km

Therefore, the radius of the orbit is approximately 24.92 km.

Please note that the answer has been rounded to two decimal places.
