Answer:
Change in velocity is -4m\s
acceleration is -2m\s^2 cause Change in velocity = final v - initial v
Explanation:
Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Thus the SI unit of acceleration is the meter per second squared .
I think
because i think thats just it
Answer:
Flourine
Explanation:
Oxidation number will be +1 for oxygen and -1 for Flourine
Answer:
0.96 g/cm3, and it will float!
Explanation:
I've explained how to do this before (remember me? lol), but ig I'll do it again..
By looking at the graph you can see that Object C has a mass of ~24 grams and a volume of ~25 cm3
Density = Mass/Volume -> 24 grams/25 cm3 = 0.96 g/cm3
Density of water is 1 g/cm3
Object C is less dense than water and therefore will float (just barely, though)

Answer:
Kinetic energy
Explanation:
Fireworks convert chemical energy into kinetic energy to send them flying upward. Hope it is correct!
