Among the choices, electromagnetic induction produces an electric current.
WHY:
Electromagnetic Induction produces an electric current when an electromotive force or voltage moves across an electrical conductor in a changing magnetic field. As an experiment, moving a bar magnet inside a coil will produce emf (electromotive force) or voltage thereby producing a current.

The International Space Station (ISS) orbits Earth at an altitude of 400 km. Using this information, plus the mass and radius of

Thepotemich [5.8K]

Answer:

v = 7671.57 m/s

T = 1.55 hours

Explanation:

mass of Earth, M = 6 x 10^24 kg

Radius of earth, R = 6400 km = 6.4 x 10^6 m

height, h = 400 km

Velocity is given by

$v=\sqrt{\frac{GM}{R+h}}$

where, G be the universal gravitational constant.

G = 6.657 x 10^-11 Nm^2/kg^2

$v=\sqrt{\frac{6.67\times 10^{-11}\times 6\times 10^{24}}{6800\times 10^{3}}}$

v = 7671.57 m/s

Let T b the period

$T=\frac{2\pi (R+h)}{v}$

$T=\frac{2\times 3.14(6800\times 1000)}{7671.57}$

T = 5566.53 second

T = 1.55 hours

You hold a bucket in one hand. In the bucket is a 500 g rock. You swing the bucket so the rock moves in a vertical circle 2.2 m

slavikrds [6]

Answer:v=3.28 m/s

Explanation:

Given

mass of rock $m=500 gm$

diameter of circle $d=2.2 m$

radius $r=\frac{2.2}{2}=1.1 m$

At highest Point

$mg+N=\frac{mv^2}{r}$

At highest Point N=0 because mass is just balanced by centripetal Force

thus $mg=\frac{mv^2}{r}$

$v=\sqrt{gr}$

$v=\sqrt{9.8\times 1.1}$

$v=\sqrt{10.78}$

$v=3.28 m/s$
