Yes and no science is a way and show us how to prove right and wrong so it’s important that you put it show they have evidence and experience to back up what is right and wrong
We know, Power = Energy / time
Here, P = 750 Watt
t = 60 sec
Substitute their values,
750 = E / 60
E = 750 * 60
E = 45,000 J
In short, Your Answer would be 45,000 Joules
Hope this helps!
Answer is option b The amplitude of the resultant wave is greater than the amplitude of either of the two individual waves.
Answer:
Ok, the minimal quantity of charge that we can find is on the electron or in the proton (the magnitude is the same, but the sign is different)
Where the charge of a single proton is:
C = 1.6x10^-19 C
Now, you need to remember that when we are working with charges, we are working with discrete math:
What means that?
If the minimum positive is the charge of one proton, then the consecutive charge will be the charge of two protons (there is no somethin in between)
So the consecutive charge will be:
C = 2*1.6x10^-19 C = 3.2x10^-19 C.
So, because we are working in discrete math, we can not have any object that has charge between 1.6x10^-19 C and 3.2x10^-19 C.
Particularly, 2.0x10^-19 C is in that range, so we can conclude that:
No, an object can not carry a charge of 2.0x10^-19 C.
Distance = speed * time, then time = distance / speed.
time = 50 / 0.4 = 125 s
