Gold is much heavier than lead. It is very dense. ... Therefore gold weighs 19.3 times as lead
Answer:
Momentum of the bowling pin is 17kgm/s
Explanation:
P(initial of ball)=+30 kg m/s
P(initial of pin)=0 because its velocity is 0
P initial = P final
30= P(ball) + P(pin)
30=13+P(pin)
P(final of pin)=+13 kg m/s and P(final of ball)= 30-13=17kgm/s
Answer;
B. Without good stability, athletes are too clumsy to perform well.
Explanation;
Stability refers to the resistance to both linear and angular acceleration, or resistance to disruption of equilibrium.
Developing and enhancing core strength and stability helps athletes to maximize their power output and enhance game day performance. Additionally, Improving core strength and stability can also help athletes reduce their risk of injury.
Answer:
the product of mass and velocity
....in my syllabus
It's still 20 kg. Mass doesn't change according to gravity, only weight changes.
