The difference between conductors and insulators is because
of electronic structure of atoms and molecules.
Anywhere we have free electrons, we have a hard conductor
where free electrons help in conduction.
In electrolytes, charged Ions do conduction.
Dielectrics (or insulators) don't have free electrons current.
Free electrons mean, the electrons that are not related with
a specific atom, they are allowed to move nearby the crystal lattice.
The answer is C. Elements
Elements cannot be broken down int simpler substances even by chemical means
D=44.13, Horizontal velocity is unimportant. The time it takes the cannon ball to fall to the ground is the key to determining the height of the cliff. where that cannon is present.
The speed of any projectile travelling along a Horizontal velocity is known as the horizontal velocity. When a particle or object is launched into the air at an angle other than 90 degrees, it moves along the trajectory path and changes the shape of the curve to a parabolic one.
the speed at which velocity changes over time. Due to its magnitude and direction, acceleration is a vector quantity. The first derivative of velocity with respect to time or the second derivative of position with respect to time are further examples. This is called acceleration.
Distance to the ground is d = 1/2gt^2,
where g is the acceleration rate of gravity (9.80665 m/s^2)
and t = 3 secs.
d = .5×9.80665×9 = 44.13 m.
