Answer:
4.12 m/s^2
Explanation:
unbalanced force means the presence of resultant force (net force)
f = 28N
m = 6.8kg
a = ?
? = 28/6.8
= 4.1176...
approximately = 4.12 m/s^2

Answer:
distance is not a vector. it is scalar
Answer:
Annihilation
Explanation:
Annihilation is the phenomenon that occurs when a particle of matter and its corresponding anti-particle of antimatter collide with each other. When this collision occurs, the particle and antiparticle "disappear", and all their mass is converted into pure energy, according to Einstein's famous equation:
where
E is the energy released
m is the mass of the two particles together
c is the speed of light
Annihilation is the process that releases the largest amount of energy at all, since the whole mass of the particles involved is 100% converted into energy. An example of annihilation is the electron-positron annihilation.
Answer:
C
Explanation:
they are still in the same plane witch means they going the same speed
