1) 4°C : It has the highest density as shown on the graph.
2) Water expands when it freezes, making it less dense than just water.
3) The ice would sink to the bottom, then the rest of the water would freeze as well, the entire lake/river/whatever will freeze eliminating the organisms that live there.
Answer:
The way that the flask is built it has 3 protective layers.... the inside layer to keep the heat in, the outside layer to reflective the cold, and a vacuum layer, which is an empty layer that limits conduction and convection
Explanation:
The energy stored in a capacitor is
E = (1/2) · (capacitance) · (voltage)²
E = (1/2) · (6 x 10⁻⁶ F) · (12 V)²
E = (3 x 10⁻⁶ F) · (144 V²)
<em>E = 4.32 x 10⁻⁴ Joule</em>
(That's 0.000432 of a Joule)

i cant see the the pic its glitched post a new one i will help
Explanation:
Answer:
The ball takes 5.66 seconds to hit the ground.
Explanation:
In this problem, the horizontal wind that interferes with the ball doesn't affect the time in which the balls hit the ground.
To find this time this is the equation for kinetic energy:
Where d is the distance, g is the acceleration of gravity and t is the time that you have to find, you can solve this equation to find t:
Replace the values:
t=5.66 s
