Kinetic energy is associated with the motion of an object.
Since the object is at rest on the ground, its velocity is zero.
Since kinetic energy is directly proportional to the square of velocity, kinetic energy of the ball on the ground is zero.
Answer:
50cm
Explanation:
because thats the only thing i got
<span>The correct answer is Na+, reduction is the gaining of electrons by ions, the ease at which an ion or an atom gains electrons depends on its position in the electrochemical series. Electrochemical series arranges atoms of elements in order, based on the ease of gaining electrons. In this case, Na+ can easily gain electrons compared to the other ions given. We can also look at it based on the electromotive force of each (EMF); +0.77 Vb. -0.25 Vc. -2.71 Vd. +0.15; this evidently shows that Na+ can undergo reduction easily compared to the other ions</span>
Density = (mass) / (volume)
Density = (17.0 g) / (25.3 cm³) = 0.672 gm per cm³. (rounded)
