Answer:
If an object pushes out an amount of water equal to its own weight, the upward force acting on it will be equal to gravity - and the object will float.
Explanation:
The buoyant force has an impact on the object in the water and equals the weight of the water displaced by the object. Every object placed in water has some buoyancy force that pushes it against the gravitational force, and this means that any object loses weight in the water.
Answer:
0.47922 kgm/s and will move right to left
Explanation:
= Mass of broccoli-tomato-pickle-onion-mushroom pizza = 235 g
= Mass of veggieburger-on-a-bun = 351 g
= Velocity of broccoli-tomato-pickle-onion-mushroom pizza = 1.65 m/s
= Velocty of veggieburger-on-a-bun = -2.47 m/s
Left to right is considered positive direction and the opposite is negative direction
Net momentum is
The combined dish has a momentum of 0.47922 kgm/s and will move right to left
There are no rules that describe how positive energy behaves
in the presence of negative energy, because there is no such
thing as negative energy.
(Wellll ... in pop Psychology, perhaps, but not in any real science.)
