C, electrons are negative, and most of the atom’s mass comes from the nucleus of the atom
Answer:
1.95 kg
Explanation:
Momentum is conserved.
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
0 = (74.9) (-0.215) + m (8.25)
m = 1.95
Because the more advances made in the world means the more we can learn on how things work and how we can better the lives of humans and other species. If we didn't have scientific advancements we wouldn't have cell phones, electric, tv, car, computers, ect. We would still be living in Cave man era with clubs and horrible language skills.
The best answer to fill in the blank should be ''continuation'' because series means a lot and lines are long, narrow, figures, so its continuation since its constant.
Answer:
135 N
Explanation:
Given that:
In a tug of war, team A pulls the rope with a force of 225 N; &
Team B also pulls with a force of 360 N
The magnitude of the resultant force is the difference between the two forces since they are positioned in the opposite direction.
Thus;
The magnitude = 360 N - 225 N
So, magnitude of resultant force on the rope = 135 N
