It takes Harry 34 s to walk from x1 = -11 m to x2 = -54 m .
miss Akunina [59]
Missing question:
"<span>What is his velocity? Please answer using two sig figs in m/s."

Solution
The relationship between velocity (v), space (S) and time (t) is
</span>v= \frac{S}{t}
<span>The space covered by Harry is
</span>S=x_1 - x_2 = -11 m-(-54 m)=43 m
<span>and so the velocity is 
</span>v= \frac{43 m}{34 s} =1.26 m/s<span>

Gemiola [76]

you tend to push off with the foot still on the boat.

Newtons 3rd law of motion hold that every action has an equal and opposite reaction.

The same principle applies when you fire a cannon - in the pirate films, you see the body of the cannon forced back as it is fired.

Take it one step further, Henry VIII flagship, “Mary Rose fired all its cannons together one day in a broad side, the opposite force rolled the ship over and sank it.

riadik2000 [5.3K]

Answer:

Option B. The planet is a very way from the center or the Sun.

Explanation:

If the surface temperature of the newly formed planet is - 20 K that means the distance of the planet from the sun in greater.

If we look at the temperature trends of the planets in our solar system, the planets closer to the sun like  Mercury, Venus have very high surface temperature but as we move move away from the the center of the solar system, i.e., Sun, the temperature goes on decreasing.
