Differentiation 2
Differentiation The differentiation is to find the amount of change at a point on a graph f(x). This is like the process of finding the slope of the tangent line when you can draw a tangent at a point on … more
Inverted Image of Microscope
Move the preparation. Why does the image move in the opposite direction? Depending on the type of microscope, how is the direction of movement different? * Cell image source: https://www4.uwsp.edu/biology/Courses/BotLab/default.htm
Why do we see only one side of the moon?
Why do we always see the same side of the moon? The moon’s rate of rotation and rate of revolution is the same.
Apparent Motion of Venus
All planets in the Solar System revolve around the Sun in a counterclockwise direction when one views them from the celestial sphere’s north pole. Mercury and Venus are inner planets in the Solar System. They are closer to the Sun … more
Parallel Circuit
Parallel Circuit is a closed circuit in which the current follows more than one pathway. In a parallel circuit, if one bulb breaks, the bulbs in the other branch stay on. In a parallel circuit, the current split up when … more
Scale of Solar System
Press the button of the planet you want to go. Orbital radii of the planets has applied the average.
Serial Parallel Circuit
In parallel circuit, The current splits up when it comes to a branch. The current in all the branches adds up to the current in the main part of the circuit. If one bulb breaks, the bulbs in the other … more
Charge Conservation
In the serial circuit, The current is the same everywhere. In the parallel circuit, The current splits up when it comes to a branch. The current in all the branches adds up to the current in the main part of … more
Electroscope
Electroscope Using an electroscope, you can determine whether an object is charged or the polarity of the charge. When the (+) charged body is close to the metal plate, the metal foil’s free electrons are attracted to the metal plate, … more
Electrostatic Induction
What happens when the charged body is close to the conductor? Electrostatic induction is a redistribution of electrical charge in an object caused by the influence of nearby charges. In the presence of a charged body, an insulated conductor develops … more
Electrostatic induction (the viewpoint of metal bonding)
What happens when the charged body is close to the conductor? Electrostatic induction is a redistribution of electrical charge in an object caused by the influence of nearby charges. In the presence of a charged body, an insulated conductor develops … more
