Answer:They are movement, nutrition, respiration, sensitivity, reproduction, excretion,and growth.
Explanation:
Answer:
6m/s
Explanation:
Data obtained from the question include:
Mass = 0.5kg
Momentum = 3 kg.m/s
Velocity =.?
Momentum is simply the product of mass and velocity as shown by the equation below:
Momentum = Mass x Velocity
Velocity = Momentum /mass
Velocity = 3kg.m/s / 0.5kg
Velocity = 6m/s
Therefore, the velocity of the ball is 6m/s
Answer:
Group 2
Explanation:
Because group 2 is very reactive and forms salts with other non metals. Example Calcium Chloride. Calcium is from group 2, forms ionic salts with other non metal, and exists as solid at standard temp and pressure.
Nuclear Fusion is when two atoms (usually Hydrogen and helium because they are very light and abundant) are smashed together to form heavier elements and in the process releases massive amounts of energy. Nuclear Fission on the other hand is when a heavier atom is split apart at the nucleus and releases large amounts of energy and free neutrons and photons. (in the form of gamma rays)
Answer:
The force applied to the object is an external force, from outside the system. When it does positive work it increases the gravitational potential energy of the system. Because gravitational potential energy depends on relative position, we need a reference level at which to set the potential energy equal to 0.
