Half maximum velocity occurs at the point of half maximum kinetic energy which is exactly halfway down.
<h3>
Conservation of energy</h3>
The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
M.A = K.E + P.E
At the maximum height, the kinetic energy of the ball while potential energy is maximum.
At the half-way down, the ball kinetic energy of the ball is equal to the potential energy.
Thus, half maximum velocity occurs at the point of half maximum kinetic energy which is exactly halfway down.

The properties of acids are: (A), (C) and (D).
Explanation:
Acids taste sour, and most
acids are poisonous. Furthermore, acids react with certain metals to
produce hydrogen gas. Few acids are corrosive as well. The option (B) is not valid because acids react with BASES (not with other acids) to produce salt and water. Hence A, C and D are the correct options.
Is D
is D because the inner layers are the Core, Radiative Zone and Convection Zone.
Answer:
i). Inverted
ii). Magnification of the image = -0.5
iii). Real
Explanation:
As shown in the ray diagram attached,
An object AB has been placed in front of converging lens (convex lens) at u = 30 cm.
F (Focus) of the lens is at 10 cm. So F = 10 cm
By analyzing the ray diagram we can measure the distance of the image on the other side of the lens (By counting the small blocks of the graph)
V = 15 cm
Characteristics of the image is:
i) Inverted
ii) Magnification of the image = 
= -0.5
ii) Real
