Answer:
The current in the solenoid=0.463 Ampere
Explanation:
Given:
Number of turns , N=420
Length of the solenoid=0.575 m
Magnitude of Magnetic Field,
We know that the magnitude of the magnetic Field inside the solenoid is
Where
- is the permeability of free space.
- n is the number of turns per unit length
- i is the current
According to question
Hence the current is calculated.
Answer: The mass is 3.58*10^-2 g
Explanation: In order to calculate the mass corresponding to of a small spherical shot of copper inside a graduate cylinder with water we have considered the total volume of water incresed after put the cooper pieces.
In this sense the total increased volume of water is equal to the volume of the 125 small spherical shot of copper so we have the following:
0.5 mL= 125* volume of each piece of cooper=125*Vcopper
Vcooper=0.5/125 mL=5*10^-7 m^3/125=4*10^-9 m^3
Therefore the mass corresponding to each copper piece is equal to:
density of copper* Vcopper piece= 8960 Kg/m^3*4*10^-9 m^3=3.58*10^-5 Kg = 3.58*10^-2 g
