Answer:
Yes, Mirror are a surface that reflects light more perfectly than ordinary objects.
Explanation:
Answer:19ohms
Explanation:
equivalent resistance=5+2+12
equivalent resistance=19ohms
That is called pseudoscience
Answer:
The strength of magnetic field is 0.2 Tesla.
Explanation:
Data from the question is
Length (L) of wire ; L=0.10 m
Current in wire ; I= 2.0 A
Force on wire ; F = 0.04 N
Angle = Right angle So, 

Now ,
We have to find the magnetic Field strength (B)
For this formula for Force on wire in magnetic field is

Further modified as

Now insert values in the formula


So, the strength of magnetic field is 0.2 Tesla.
Answer:
Because it is made by two different unit force (F) and displacement(s)
