Conception is the correct answer
Answer:
0.012 N
Explanation:
The formula to apply is that adopted from the Ampere law which is;
F= μ* I₁*I₂*l /2πd where
F is force that one conductor exerts on the other.
μ = magnetic permeability of free space = 4π×10⁻⁷ T. m/A
I₁ = current in conductor one=10 A
I₂ = current in conductor two= 10 A
l= length of conductor= 3 m
d= distance between the conductors = 5 mm = 0.005 m
Applying the values in the equation
F= 4π×10⁻⁷ *10*10*3 / 2π*0.005
F= 6 * 10⁻⁵ / 0.005
F=0.012 N
Answer:
The frequency does not depend on the amplitude for any (ideal) mechanical or electromagnetic waves.
In electromagnetism we have that the relation is:
Velocity = wavelenght*frequency.
So the amplitude of the wave does not have any effect here.
For a mechanical system like an harmonic oscillator (that can be used to describe almost any oscillating system), we have that the frequency is:
f = (1/2*pi)*√(k/m)
Where m is the mass and k is the constant of the spring, again, you can see that the frequency only depends on the physical properties of the system, and no in how much you displace it from the equilibrium position.
This happens because as more you displace the mass from the equilibrium position, more will be the force acting on the mass, so while the "path" that the mass has to travel is bigger, the mas moves faster, so the frequency remains unaffected.
Answer:
2.8351×10^7 N/kg
Explanation:
We know that,
W = mg -------(1)
where W = weight, m = mass, g = gravitational acceleration
Also from Newton's law of gravitation we know that,
F = GMm/r²
Where,
F = gravitational force,
G = universal gravitational constant
M,m = masses of object under gravitational influence
r = distance between the two center of masses.
Here we get
F = (Gm/r²)M -------(2)
From 1 and 2
The acceleration due to gravity = gravitational field intensity
So if you consider the gravitational field intensity at the surface of the asteroid,it is equal to the acceleration due to gravity at the same place.
So we get,
g = (6.67×10^-11)×9.3835×10^20/(47²) = 2.8351×10^7 N/kg
