Answer:
hi,human absorb 0oxygen =aborption ,reflection =the light that entered in the water,refraction =the light that pass outside the water
Explanation:
Answer:
Explanation:
First of all the mass in in g and we need it in kg, so let's convert it.
Now we can proceed.
Find the momentum.
Now let's find the kinectic energy that this rock has in Joules.
Answer: repeatable
Explanation: Accurate repeatable is needed in a valid experiment. I think
Answer:
12.02 m/s north of east
Explanation:
Let be the horizontal and vertical velocity of the 3rd piece, positive in the East and North direction. Also let m be the mass of the 2 smaller pieces, so 2m is the mass of the 3rd piece.
We can solve for the 2 velocities components using law of momentum conservation. Before the explosion, the total momentum was 0 because the coconut was at rest. After the explosion:
- In the x direction:
negative 17 because 1 piece flew west
- In the y direction
negative 17 because 1 piece flew south
So the speed and direction of the 3rd piece is
north of east
