Answer: The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe = hf − BE, where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.
Explanation:
Answer:
1. An objects position is its <u>distance</u> and <u>direction</u> from a <u>reference point</u>.
2.<u>Displacement</u> is <u>difference</u> between its <u>final</u> and <u>initial</u> positions.
Explanation:
For any position we required a reference point and the distance between the reference point and the object.
For example:
an object is 40 m away from a table.
Here the <u>distance is 40 m</u> from a reference point that is <u>a table.</u>
Displacement is the difference between its final and initial position.
For example
A person walk 20 km and then returned back 10 km.
Here distance traveled by a person is 30 km. But displacement is (20 - 10) that is the difference between final and initial position.
So displacement is 10 km.
The length of time that an action or state persists. The given L-shaped object made of two rods oscillates at a frequency of 2π√√2L/3g.
The rod weighs m grams.
The length of a single rod is L.
If it is connecting at, as indicated by the query, then the moment of inertia of the combined system follows.
mL²/3+3L²/3=2mL²/3
Here, I denotes the rod's moment of inertia, d denotes the separation of the center of gravity from the fixed point, and T denotes the length of time the L-shaped object oscillates.
Length of pendulam
Lcos45=L*1/√2=L/√2
Caluclate the time period
T=2π√I/mgl
=2π√2*mL²*√2/3*2mgl
oscillates at a frequency = 2π√√2L/3g
