The answer would be the Scientific Method.
Answer:
Wavelength = 10 m
Explanation:
Given:
Speed = 100 m
Frequency = 10 Hz = 10
To find : Wavelength = ?
We know that the relationship between wavelength λ, frequency f and speed v is given by the equation
v = fλ
Therefore wavelength λ = v/f
= 100 m / 10 m
= 10 m
Hence wavelength = 10 m

Electric field due to a single point charge at the center of the square is given as E = 2 N/C
Now we place three identical charges on rest of the corners
So the electric field at the center will be due to all four charges will be of same magnitude
but the direction of all four charges electric field be like they all cancel the field of its opposite charge
So here due to vector property of the charges we can say that the electric field of all four charges will cancel each other and net field due to all four charges at center will be ZERO
so correct answer will be
<em>b. The magnitude of the net electric field at the center of the square is 0 N/C.</em>
Mechanical Advantage is the value which tells us the factor by which the machine is able to convert the force applied to it to its output.
Ideal Mechanical Advantage of wheel and axle is calculated by
IMA = Wheel Radius / Axle Radius
By virtue, the higher the computed IMA the lower the force needed to be exerted, this is the purpose for using machine, lower input force but larger output. (The smalled the axle radius compared to the wheel radius is the better setup.)
