Yes water does expand when changing from a liquid to a solid (water to ice)

Answer:Yes, water indeed expands when it changes form from liquid to solid. And this is because water has a property called “hydrogen bonds”, and these bonds occur between each water molecule. But when water is in a liquid form these hydrogen bonds break more easily and occur less frequently. When the temperature drops the kinetic energy also drops, which in turn makes hydrogen bonds form more frequently. So the water molecules form a lattice, which is less dense than regular liquid water.

Stacey runs around a 400 meter track 2 times in 5 minutes. How does her displacement differ from her distance? *
liq [111]

Answer:

Distance is 800 m and Displacement is 0 m

Explanation:

Total Distance

= 400(2)

= <u>800</u><u> </u><u>m</u>

Total Displacement

= <u>0</u><u> </u><u>m</u> since she returns to the same spot

RideAnS [48]

Answer:

K_{total} = 19.4 J

Explanation:

The total kinetic energy that is formed by the linear part and the rotational part is requested

         K_{total} = K_{traslation}  + K_{rotation}

let's look for each energy

linear

        K_{traslation} = ½ m v²

rotation

        K_{rotation} = ½ I w²

the moment of inertia of a solid sphere is

       I = 2/5 m r²

we substitute

       K_{total} = ½ mv² + ½ I w²

           

angular and linear velocity are related

           v = w r

we substitute

           K_{total} = ½ m w² r² + ½ (2/5 m r²) w²

           K_{total} = m w² r² (½ + 1/5)

           K_{total} = \frac{7}{10} m w² r²

let's calculate

           K_{total} = \frac{7}{10}   6.40 16.0² 0.130²

           K_{total} = 19.4 J

James Naismith was a physical education teacher

Sprinfield College

Upon the request of his boss, Naismith was tasked to create an indoor sports game to help athletes keep in shape as they endured the cold New England winters. Naismith's boss also stipulated that this new game should be "fair for all players and not too rough."

I just looked it up hope this helps tho.
