Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
What are the disadvantages of polymer fibers optics? The ends of polymer fibers can't operate along with high temperatures. Illuminators or light sources are required with a sc
Subtracting 2 Vectors This is where things obtain a bit more interesting. What we required to note here is in which in Physics a negative sign simply means "in the opposite dir
In this case both source and screen are effectively at infinite distance from the diffracting device. Basic types: Diffraction at single slit, double slit and diffracting gratin
What is the angular acceleration of the Earth around the Sun? What equation is used to derive it?
When two objects collide like there velocities are not in the line of action of contact force then the collision is known as oblique collision. We can split also oblique collisi
The process of transformation of one element into another by bombarding it with high energy particles is called "Artificial transmutation". Artificial radio activity is the proc
Who are the best system integrators? Being fairly the opposite of fiber optics manufacturers, system producers are generally small companies. In this case size has the opposite
How fast must a spacecraft travel relative to the earth for each day on the spacecraft to correspond to 2d on the earth? By standard equation, for the time t to the earth to co
The ratio of specific charge of a proton and an alfa-particle is: (1) 2 : 1 (2) 1 : 2 (3) 1 : 4 (4) 1 : 1 Ans:(1) 2 : 1
