Jaden has a mass of 45 kilograms on Earth. Jupiter has more gravity than the Earth. On Jupiter, Jaden's mass will be O more than

Dovator [93]

Answer:

m = 45 kg

Explanation:

Given that,

Mass of Jadan, m = 45 kg on Earth

Jupiter has more gravity than the Earth.

Mass of an object is the amount of matter contained inside an object. We need to tell about the mass of Jaden on Jupiter. The mass of the object remains same everywhere.It does not change in any of the location.

Hence, Jaden's mass will be 45 kg on Jupiter.

trapecia [35]

Answer:N=13.53 rpm

Explanation:

Given

radius $r=7.80 m$

Centripetal acceleration $a_c=1.6 g$

and centripetal acceleration $a_c=\omega ^2r$

where $\omega =angular\ velocity$

$1.6\times 9.8=\omega ^2\times 7.8$

$\omega ^2=2.0102$

$\omega =1.417 rad/s$

and $\omega =\frac{2\pi \cdot N}{60}$

$1.417\times 60=2\pi \cdot N$

$N=13.53 rpm$
