Explanation:
uhhhhh idk what to write here. Hope this helped;))
In this case, the one that responsible for avoiding a collision would be: <span>the operators of both boats
When the operators of each boat spot each other in a same area, they should use their siren to notify each other's position and uses communication device to determine how they should pass through to avoid collision</span>
The answer is B. Transfer electrons
Answer:
A= 150 J
Explanation:
Kinetic energy is the energy of an object in motion.
The formula for kinetic energy is ;
K.E = 1/2 * m *v² where m is mass and v is velocity
Work done is equal to change in kinetic energy
W= Δ K.E
Given that K.E = 150 J
Taking that the ball was stationary before it was thrown, this makes its initial kinetic energy to be 0 J so the work done will be
W= Δ K.E
W= 150 - 0
W= 150 J
