Answer:
Volume of head = 1000 cm^3
Explanation:
The head of a normal person can be assumed as a sphere with radius 10 cm.
Volume of sphere, where r is the radius.
We have approximate radius = 10 cm.
Approximate volume of head
In the given options the closest value to the approximate volume is 1000 cm^3.
So, volume of head = 1000 cm^3

Explanation:
Answer:
Explanation:
According to Equations of Projectile motion :
vsin(x) = 11 * 9.8 / 2 = 53.9 m/sec
(A) v (Initial velocity) = 11 * 9.8 / 2 * sin(35) = 94.56 m/sec
(B) Maximum Height = 53.9 * 53.9 / 2 * 9.8 = 142.2 m
(C) Horizontal Range = 94.56 * 0.81 * 11 = 842.52 m
Answer:
providing energy to an atom can allow the electron in its non valence shell to obtain energy and move to a higher energy orbital and act as a valence electron.
Explanation:
The (more) speed an object has, the (lower) the potential energy and the (higher) the kinetic energy. (I believe that is correct but it’s been a while since I’ve done this)
