<h2>QUESTION:- Which formula below correctly states Coulomb's Law?</h2>
<h2>OPTIONS:- </h2>
<h2>ANSWER:- </h2>
F is directly proportional to the product of the charges
F is inversely proportional to the square of the distance between them
from above 2 equation:-
we get:-
To remove proportionality sign we use constant for this case we r using constant k
So your answer is :-
OPTION A.
The wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
The electric current amount will vary according to the resistance value when connected to a voltage of a power supply. If resistance is reduced, current will increase. So, if the resistance is infinite (open circuit), the current could be considered zero, or infinitesimal small, if the resistance is zero (of infinitesimal small), the current will tend to be the maximum the power supply can provide. Here is the case of the power supply capability, input resistance, capacity to hold and regulate the output voltage to a certain maximum current, etc. Normally when you short circuit (zero ohms resi
Answer:
time is 0.5660 s
and time is - 3.62431 s
Explanation:
velocity u = 15 m/s
height s = 10 m
acceleration due to gravity g = –9.8 m/s²
to find out
time
solution
we will apply here distance equation that is
s = ut - 1/2× gt² ...........1
here put all these value and get time t
here s is height and g is -9.8
so
s = ut - 1/2× gt²
10 = 15t - 1/2× (-9.8)t²
10 = 15t + 4.9t²
solve it we get t
t = 0.56630 and -3.62431
so time is 0.5660 s
and time is - 3.62431 s
