Answer:
-730KJ
Explanation:
According to the first law of thermodynamics;
Let the total energy of the system be ∆E
Let heat be q and let work the w
Since the energy decreases ∆E is negative
Since work is done on the system w= positive
So;
- 250 = 480 + q
q = -250 - 480
q=-730KJ
The x and y coordinates of the particle at this moment is (6x + 4.5y) m.
<h3>
Position of the particle </h3>
The position of the particle at any instant is determined from the velocity and acceleration of the particle as shown below.
v² = u² + 2as
where;
- v is the final velocity of the particle
- u is the initial velocity
- a is the acceleration of the particle
- s is the position of the particle
v² = 0 + 2as
v² = 2as
s = v²/2a
<h3>X and y - coordinates of the particle</h3>
![s_x = \frac{v^2}{2a_x} = \frac{6^2}{2(3)} = 6\ m\\\\s_y = \frac{v^2}{2a_y} = \frac{6^2}{2(4)} = 4.5 \ m\\\\s = (6 x \ + 4.5y)m](https://tex.z-dn.net/?f=s_x%20%3D%20%5Cfrac%7Bv%5E2%7D%7B2a_x%7D%20%3D%20%5Cfrac%7B6%5E2%7D%7B2%283%29%7D%20%3D%206%5C%20m%5C%5C%5C%5Cs_y%20%3D%20%5Cfrac%7Bv%5E2%7D%7B2a_y%7D%20%3D%20%5Cfrac%7B6%5E2%7D%7B2%284%29%7D%20%3D%204.5%20%5C%20m%5C%5C%5C%5Cs%20%3D%20%286%20x%20%5C%20%2B%204.5y%29m)
Thus, the x and y coordinates of the particle at this moment is (6x + 4.5y) m.

Answer:
Well techinacally it is because the glass is a different density than the surrounding air. So it cannot be C. I am not sure between A and B, but I would assume that it is B since glass is a solid and solids have higher densities than air.
