Answer:
because the mass of the copper is higher than the mass of the gold.
Explanation:
The ability to convert voltage to and from mechanical stress.
Answer:
The speed of the projectile upon returning to its starting point is 50 m/s.
Explanation:
Given;
initial velocity of the projectile, u = 50 m/s
The velocity of the projectile is maximum before hitting the ground. As the object moves upward, the velocity reduces as it approaches the maximum height, at the maximum height the velocity becomes zero. Also, as the object moves downward, the velocity starts to increase and becomes maximum before hitting the ground.
Therefore, the speed of the projectile upon returning to its starting point is 50 m/s.
Answer:
178200
g mile pounds
Explanation:
Work= Force * Distance= Fh
F=ma=mg where m is mass and g is acceleration due to gravity
Work= 165 pounds *g* 1080 m= 178200
g mile pounds
