Explanation:
Ionization Energy Trends
Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous phase. Conceptually, ionization energy is the opposite of electronegativity. ... As a result, it is easier for valence shell electrons to ionize, and thus the ionization energy decreases down a group
Answer:
Time period for Simple pendulum, 
Explanation:
The Simple Pendulum
Consider a small bob of mass
is tied to extensible string of length
that is fixed to rigid support. The bob is oscillating in the plane about verticle.
Let
is the angle made by string with vertical during oscillation.
Vertical component of the force on bob,
Negative sign shows that its opposing the motion of bob.
Taking
as very small angle then, 
Let
is the displacement made by bob from its mean position ,
then, 
so,
........(1)
Since, pendulum is in hormonic motion,
as we know, 
where
is the constant and 
.........(2)
From equation (1) and (2)


Since, 


Answer:
D by spinning magnets to induce electric current.
Answer: A. vector
Explanation:
Movement is the change of position of a body at a certain time. The body that experiences this change of position is called mobile.
In this sense, the <u>displacement</u> is the distance in a straight line between the initial and final position of this mobile, which differentiates it from <u>the trajectory, </u> which is the <u>path followed by the body in its movement and a scalar magnitude.</u>
Hence, the displacement is a vector.
