Answer:
B
Explanation:
Let T be the orbit period and a be the radius of orbit.
For T^2= k× a^3 (k is a constant)
there seems to be an indirect relationship between two variables.
Answer:De acuerdo con la ley de inducción electromagnética de Faraday, la tasa de cambio del flujo magnético vinculado con la bobina es directamente proporcional a la fem inducida en la bobina.
e = - d∅ / dt
Entonces, si el cambio de flujo es mayor, la fem inducida es mayor.
¡espero haber ayudado a tener un buen día! :)
Explanation:
According to the Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is directly proportional to the induced emf in the coil.
e = - d∅ / dt
So, if the flux change is more the induced emf is more.
i hope i helped have a good day! :)

Gamma raidiation and beta and alpha particles
Answer:
The International Space Station move at 7.22 km/s.
Explanation:
Orbital speed of satellite is given by
, where G is gravitational constant, M is mass of Earth and r is the distance to satellite from centre of Earth.
r = R + h = 6350 + 1400 = 7750 km = 7.75 x 10⁶ m
G = 6.673 x 10⁻¹¹ Nm²/kg²
M = 5.98 x 10²⁴ kg
Substituting

The International Space Station move at 7.22 km/s.
