Answer:
True
Explanation:
An atom's valance electrons are those electrons that have the highest energy. Atoms tend to be stable and nonreactive if they have the highestvalence electrons. In the periodic table, the number of valence electrons in each element decreases from left to right across each period.
Displacement is the area under the velocity/time graph. So for example this object's displacement in the first 3 seconds is (1/2)(3sec)(12.5 m/s)= 18.75m. (and then it starts backing up, displacement decreasing, after 3sec when velocity is negative).
But This object is never speeding up. Its velocity is smoothly decreasing at (25/6) m/s^2 (the slope of the graph). So the answer to the question is actually zero.
Gravitational force = Gxm1xm2 /r^2
This equation depends only upon object's masses and distance between them. So option b is correct
Answer: The wheel's average rotational acceleration is -0.4 radians per second squared (rad/s^2)

Answer:
Th e correct answer is B. Balance
Explanation:
Balance is an ability of a body to maintain the line of gravity with negligible postural sway. Sway is the horizontal movement of the center of gravity of a body if a body is standing still.
If you want to stay for a long period of time in one position without movement, then you need balance. So the term refers to the use of strength to hold the body's position is balance.
Agility refers to the flexibility of the body or jumping
Power means Strength in general
Speed is the ability that how can a person run fast.
