Answer:
assuming the air resistance = 0
so the acceleration is almost constant at 9.82 m/s²
Answer:
The base unit for time is the second (the other SI units are: metre for length, kilogram for mass, ampere for electric current, kelvin for temperature, candela for luminous intensity, and mole for the amount of substance). The second can be abbreviated as s or sec.
Explanation:
Answer:
8.1345°
Explanation:
We apply
to the wire to obtain:

#The magnitude of the magnetic force acting on the wire is given by:

#Substitute for
to obtain:

Solve for
:
![\theta=sin^{-1}[\frac{IlB}{mg}]](https://tex.z-dn.net/?f=%5Ctheta%3Dsin%5E%7B-1%7D%5B%5Cfrac%7BIlB%7D%7Bmg%7D%5D)
We the substitute the numerical values to calculate the equilibrium angular displacement:
![\theta= sin^{-1}[\frac{0.2A\times0.52m\times 0.040T}{0.003\ kg\times9.8m/s^2}]\\\\=8.1345\textdegree](https://tex.z-dn.net/?f=%5Ctheta%3D%20sin%5E%7B-1%7D%5B%5Cfrac%7B0.2A%5Ctimes0.52m%5Ctimes%200.040T%7D%7B0.003%5C%20kg%5Ctimes9.8m%2Fs%5E2%7D%5D%5C%5C%5C%5C%3D8.1345%5Ctextdegree)
Hence, the equilibrium angular displacement of the wire from vertical if the horizontal magnetic field is 8.1345°
When you melt a solid the heat creates energy, when you heat up molecules they will move quicker and start to somewhat break apart into a liquid structure.
