Answer:

Planetary satellites vary greatly in size, from very small, to some that are larger than some planets.

Explanation:

Natural sateletes are celestial bodies that orbit other larger celestial bodies. The solar system has several satellites, the best known being the moon, the natural satellite of planet Earth. The planets of the solar system have different sizes, just like the natural satellites. Thus, there are satellites larger than planets. The moon itself is a larger satellite than some planets, like Mercury.

PLEASEEEEEE HELP
emmainna [20.7K]

Answer:

8.89 m/s² west

Explanation:

Assume east is +x.  Given:

v₀ = 120 m/s

v = 0 m/s

t = 13.5 s

Find: a

v = at + v₀

0 m/s = a (13.5 s) + 120 m/s

a = -8.89 m/s²

a = 8.89 m/s² west

a 0.199 kg snowball moving west makes an inelastic collision with a 2.89 kg box moving 0.523 m/s west. afterward,they move west
kogti [31]

Answer:

The initial velocity of the snowball was 22.21 m/s

Explanation:

Since the collision is inelastic, only momentum is conserved. And since the snowball and the box move together after the collision, they have the same final velocity.

Let m_1 be the mass of the ball, and v_1 be its initial velocity; let m_2 be the mass of the box, and v_2 be its velocity; let v_f be the final velocity after the collision, then according to the law of conservation of momentum:

m_1v_1+m_2v_2=v_f(m_1+m_2).

From this we solve for v_1, the initial velocity of the snowball:

\boxed{v_1=\frac{v_f(m_1+m_2)-m_2v_2}{m_1}}

now we plug in the numerical values m_1=0.199\:kg, m_2=2.89\:kg, v_2=0.523\:m/s, and v_f=1.92\:m/s to get:

v_1=\frac{1.92*(0.199+2.89)-2.89*0.523}{0.199}

\boxed{v_1=22.21\:m/s}

The initial velocity of the snowball is 22.21 m/s.

<em>P.S: we did not take vectors into account because everything is moving in one direction—towards the west.</em>

An empty can of soda is yeeted (thrown) into a crowd. Then, a full can of soda is yeeted into a crowd. Throwing the full can too
4vir4ik [10]

Answer:

Newton's third law of motion.

Explanation:

We are told the force needed to throw the full soda can was more than that needed to throw the empty can.

Now, the weight of the full soda can will be more than that of the empty can. Therefore, the full can will demand more force than that of the empty can due to Newton's third law of motion which states that to every action, there is an equal and opposite reaction.
