Moons that show few craters probably

1 answer:

4 0

Moons that display few craters presumably. They all pass straight over the equator of the globe. Uranus's five biggest moons. have the closest magnetic field axis.

<h3>Which 4 moons are known?</h3>

There are many fascinating moons around the globe, but the Galilean satellites—Io, Europa, Ganymede, and Callisto—the first four moons identified beyond Earth—hold the most scientific curiosity.

<h3>Can Earth have Two moons?</h3>

Moon and Earth

The basic explanation is that Earth only has one moon, that we name “the moon”. It is the biggest and brightest object in the night sky, and the only solar system body except Earth that humanity have visited in our space travel activities.

a student attaches a 0.5 kg object to a 0.7 m string and rotates the object around her head and parallel to the ground. how much

Marina CMI [18]

The object would have a centripetal acceleration <em>a</em> of

<em>a</em> = (12 m/s)² / (0.7 m) ≈ 205.714 m/s²

so that the required tension in the string would be

<em>T</em> = (0.5 kg) <em>a</em> ≈ 102.857 N ≈ 100 N

A comet fragment of mass 1.96 × 1013 kg is moving at 6.50 × 104 m/s when it crashes into Callisto, a moon of Jupiter. The mass o

Andrej [43]

Answer:

Recoil speed, $1.17\times 10^{-5}\ m/s$

Explanation:

Given that,

Mass of the comet fragment, $m_1=1.96\times 10^{13}\ kg$

Speed of the comet fragment, $v_1=6.5\times 10^4\ m/s$

Mass of Callisto, $m_2=1.08\times 10^{23}\ kg$

The collision is completely inelastic. Assuming for this calculation that Callisto's initial momentum is zero. So,

$m_1v_1=(m_2+m_2)V$

V is recoil speed of Callisto immediately after the collision.

$V=\dfrac{m_1v_1}{(m_2+m_2)}\\\\V=\dfrac{1.96\times 10^{13}\times 6.5\times 10^4}{(1.96\times 10^{13}+1.08\times 10^{23})}\\\\V=1.17\times 10^{-5}\ m/s$

So, the recoil speed of Callisto immediately after the collision is $1.17\times 10^{-5}\ m/s$

erma4kov [3.2K]

Answer: 1: kinetic energy and velocity are at zero when the magnets are held apart, and both increases rapidly when they are released and move together. Energy stored in the magnetic field decreases.

2: The energy stored in the system is converted to kinetic, thermal, and sound energy.

3: The energy stored in the magnetic field does not change.

4: Some of the energy stored is converted into kinetic and thermal energy.

5: Two small repelling magnets hold each other in place.

Just took the quiz all are correct! I hope this helps you! :)
