Answer:
Energy remain conserved while converting its form from one to another
Explanation:
As per the conservation of energy, energy always changes its form from one form to another and it is neither destroyed nor created. The total amount of energy always remains the same.
There are several forms of energy such as thermal energy, electrical energy, nuclear energy, electromagnetic energy, etc.
For example –
During any chemical reaction, form of one chemical changes into another. In this process some amount of chemical energy remains conserved while the deficit in total starting energy is released as heat and light energy
The triarchic theory of intelligence was formulated by Robert J. Sternberg, a prominent figure in the research of human intelligence. The theory by itself was groundbreaking in that it was among the first to go against the psychometric approach to intelligence and take a more cognitive approach
The speed of sound follows the same rules, just like any other speed, if the acceleration is zero.
distance = speed * time
distance = 2m
speed = 333m/s
Solve for time t.
Answer:
Explanation:
a ) If x be the position of n the bright fringe on the screen , following formula holds .
x = n (λD / d) ; λ is wave length , D is screen distance and d is slit separation .
If we increase the value of λ or wave length, x will increase so central fringe along with all the fringes will shift away from the centre .
If we increase the value of D or screen distance , it will also increase x , so fringes along with central fringe will shift away from the center.
b ) Fringes ,whether bright or dark , both shift together , either towards or away from the center .
So to move the dark spots towards the center , we need to do the opposite to what we did in the first case , ie decrease the wavelength or decrease the screen distance .
