THOMSON'S ATOMIC MODEL:-
According to Thomson's atomic model positive charge is distributed uniformly over the entire body of the atom while the electrons are embedded in it. Similar to the seeds in a water melon.
Thomson's model failed to explain observed spectra emitted by an atom .
A step-up transformer works on 220V and gives 2A to an external resistor. The turn ratio between the secondary and primary coils is 2 : 25. Assuming 100% efficiency, Determine the
yes.fricton is working always opposite to the motion
What is the echo of the launched pulse? Any discontinuity into the medium of propagation of an ultrasonic pulse provides rise to back-reflection that travels back to the input
Carbon: Atomic number 6 Symbol C Atomic weight 12.011 Discovery Carbon exists fre
Earth's atmosphere is separated into four layers: The troposphere (0-10 km), the stratosphere (10-50 km), the mesosphere (50-80 km), and the thermosphere (80-500 km).
The integral in Ampere's Law is an integral. Answer: The integral is an integral along (over) a closed path (curve).
(1) The first practical application for piezoelectric devices was sonar, first developed during worldwar1. Piezoelectric materials are as a source of ultrasonic waves. At sea, they
Motion of an object in a plane is known two dimensional (2-D) motions. For 2-D motion acceleration or velocity can be defined by two elements in any two mutually perpendicular dire
The atomic weight of an element is double its atomic number. If there are four electrons in 2P orbital, the element is : (1) C (2) N (3) O
