Answer:
1.001 m
Explanation:
We have to find the least measurement of the instrument.
In this case the least measurement = 1 mm
= (1/1000) m
= 0.001 m
The measurement that is precise from this instrument should be to the nearest thousandth when taken in meters.
Therefore the answer is: 1.001 m
Answer:
2.00976
Explanation:
B = Magnetic field = 1.99 T
= Vacuum permeability =
= Magnetic moment of each electron =
n = Number density of atoms =
N = Number of electrons per atom
Magnetic field is given by
The number of electrons per atom contribute to the saturated field of iron is 2.00976
Answer:
3 Ω
Explanation:
I find a calculator with a reciprocal key quite useful for calculating parallel resistance.
Req = 1/(1/r1 +1/r2 +... +1/rn))
Of course, resistors in series add.
The far right two branches are 10 Ω in parallel with (8+2) Ω = 10 Ω. Of course, the parallel combination of two equal-value resistors is half the value of either of them. Thus the two right branches resolve to 5 Ω, which is then added to 1 Ω to give an effective middle section that is 12 Ω || 4 Ω || 6 Ω.
That combination has an effective resistance of ...
Req = 1/(1/12 +1/4 +1/6) = 1/(1/12 + 3/12 +2/12)) = 12/6 = 2 . . . ohms
This is effectively in series with the upper left 1 Ω resistor, so the equivalent load on the source is 1+2 = 3 Ω.
When you rub inflated balloon with your hair or your kitten's fur, charge is induced on all over the balloon's surface. This is called "charging by friction" because you developed charges by rubbing to bodies with each other. It will also stick on your wall you can check it out. This is because of "unlike charges attract each other". Rubbed balloon and wall possessed unlike charges which made them stick together.
Answer:
Explanation:
It is given that,
Magnitude of vector A,
Magnitude of vector B,
Dot product of two vectors,
Let is the angle between the two vectors. We know that the angle between two vectors is given by the formula of dot product as :
So, the angle between two vectors is 58.26 degrees. Hence, this is the required solution.
