Answer:
The balance will be upset and it will tip to the side of the still pumped ballon.
Explanation:
Given that the balloons are pumped to more than atmospheric pressure it means that the air inside has a higher density than the air outside. If you punture one balloon the air will be released and now you have on both sides the weight of the balloons itselves, but on the side of the still pumped balloon you will have a greater amount of air (is more dense) so more weight. Considering this, the balance will be upset and it will tip to the side of the still pumped ballon.
Answer:F/L = μ0*I²/2πd
Explanation:
Both wires carries current of the value (I) and are separated by the distance (d).
The length of both wires is (L).
The first wire creates a magnetic field of the magnitude according to Bio-savart law
B=(Uo * I)/2πd
This magnetic field has the ability to exert a force F on the second wire.
This force (F) is given as
F=BIL* sin θ
θ here is 90 because the magnetic field is perpendicular to the length of the second wire.
Thus the value of sin 90 = 1
Hence F= BIL
But B=(Uo * I)/2πd.
We have that F= B=[(Uo * I)/2πd] x IL
Thus we have that F= [Uo* I²/2πd] x L
By rearranging, and bringing L to the left hand side of the equation, we have that
F/L = [Uo* I²/2πd]

there's a formula that i definately don't remember but it exists
Answer:
The ratio of the model size is 1 : 2000
Explanation:
Given
Real Diameter = 0.012 um
Scale Diameter = 24 um
Required
Determine the scale ratio
The scale ratio is calculated as follows;
Substitute values for real and scale measurements
Divide the numerator and the denominator by 0012um
Represent as ratio
<em>Hence, the ratio of the model size is 1 : 2000</em>
