I’m 95% sure it’s covalent bonds.
C, electrons are negative, and most of the atom’s mass comes from the nucleus of the atom
Volume= Length X width X height.
Plug in the values for each and solve for the volume.
V= (L)(W)(H)
V=(4cm)(5cm)(10cm).
Answer:
-6112.26 J
Explanation:
The initial kinetic energy, is given by
} where m is the mass of a body and is the initial velocity
The final kinetic energy, is given by
where is the final velocity
Change in kinetic energy, is given by
Since the skater finally comes to rest, the final velocity is zero. Substituting 0 for and 12.6 m/s for and 77 Kg for m we obtain
From work energy theorem, work done by a force is equal to the change in kinetic energy hence for this case work done equals <u>-6112.26 J</u>
