Why is Angle 35?The angle between the central maxima and first order is 35(which is the theta in the equation dsin(theta)=n(lamda) )
1x10^-6*sin35=1(lamda)
lamda=5.7x10^-7 which is 574nm(C)
P=E/t, KE=1/2(m)(v^2), D=m/VHow to solve this
Because they gave the angle between the two first order maximum. The angle in the equation dsin(theta)=n(lamda) is the angle between the central maxima and the order, so to get this angle you divide 70 by 2 which is 35.Why is Angle 35?
That's good but I'm asking myself...that won't be showing offThey're great but I don't like to show off.
When the source of wave is travelling at a higher speed, the observed frequency rises(you can test this using values and the formula), so A and B are ruled out. When a source of wave approaches an observer, the observed frequency increases. So, initially the observer was detecting a microwave with a higher frequency than the microwave's actual frequency. So, when the microwave emitter stops, the observed frequency falls below f0. So the answer is C.View attachment 64117
Hellp ? :/
What were your grades?That's good but I'm asking myself...that won't be showing off
Why do u ask?What were your grades?
Just curious . I'll tell you mine but nerds firstWhy do u ask?
Negligible internal resistance so no voltage drop inside batteryCan anyone explain me the following question?

U firstJust curious . I'll tell you mine but nerds first
U first
Power output of the cell is the energy it converts from chemical to electrical per unit time and since there is no internal resistance, so all of this energy is dissipated in the resistorsCan anyone explain me the following question?

Right!5A's 2B's 1C :/
Not being shyComeon don't be shy
But how come power outcome equal to power loss in resisters I am confused at this point.Negligible internal resistance so no voltage drop inside battery
You are kidding me ....Not being shy
7A*s........................................... And 1A
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
