Answer:
Explained
Explanation:
Displacement is the change in the position of an object with reference to a starting point. for displacement to occur the position of the object must change.
Here the bacteria although moving but it is moving back and forth, meaning its initial and final positions are the same and hence no displacement. Whereas distance is the total distance traveled no matter in what direction. Hence, The total distance traveled by a bacterium is large for its size, while its displacement is small.
CO₃
Explanation:
The polyatomic ion in the compound CaCO₃ is CO₃.
A polyatomic ion is an ion that is made up of more than one atom that has singular property.
They are usually called radicals.
CaCO₃ ⇒ Ca²⁺ + CO₃²⁻
CO₃²⁻ is a polyatomic ion because it is made up of more than one atom.
The CO₃²⁻ is called a carbonate group.
It is made up of:
- one atom of carbon
- 3 atoms of oxygen
- a net charge of 2-

Rarefraction - spot on a compressional wave where the waves are farther apart.
Answer:
see explanation
Explanation:
Given quantities:
radius = r = 0.0558 [m]
current = I = 0.23 [A]
Now we solve this by obtaining the torque acting on the dipole
We obtain the magnetic moment vector M, first, |M| is defined as 
, where A is the cross-section area of the loop which is ![A = \pi r^2=\pi (0.0558)^2= 0.00978 [m^2]](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2%3D%5Cpi%20%280.0558%29%5E2%3D%200.00978%20%5Bm%5E2%5D)
then
![|M| = 0.23*0.00978 = 0.00225 [A/m^2]](https://tex.z-dn.net/?f=%7CM%7C%20%3D%200.23%2A0.00978%20%3D%200.00225%20%5BA%2Fm%5E2%5D)
now the magnetic moment vector is equal to the magnetic dipole moment vector multiplied the magnitude we just obtained 
Now:
a )
b) 
a) the determinant gives us:
b) the dot product gives = ![-1*-7.2*10^{-6} = 7.2*10^{-6}[J]](https://tex.z-dn.net/?f=%20-1%2A-7.2%2A10%5E%7B-6%7D%20%3D%207.2%2A10%5E%7B-6%7D%5BJ%5D)
