When you multiply two numbers, round the answer to the least number of significant figures available. 67.6 has three significant figures, and 1.2 has two significant figures. So we round to two significant figures.
Answer:
You answered your own question, I'm confused about what you're asking for.
Explanation:
Start with what you know and list your knowns and unknowns
F = ma
F= 3N
m = 6kg
a =?
3N = 6kg x a
solve for a
3N / 6kg = a
Answer:
False
Explanation:
The direction of magnetic field on a current carrying conductor can be determined by the Fleming's right hand rule where
- The thumb represents the direction of motion
- the index finger represents the direction of field.
- The middle finger is the direction of induced current.
When two conductors carrying currents flowing in opposite direction, the magnetic field will be in the same direction hence they will repel.
<u><em>When the currents in them flow in same direction, then it means the magnetic field will be opposition and there will be a force of attraction between the conductors.</em></u>
