Hardness is when one material can scratch another material if it’s harder than the other material. The resistance is to be scratched.
Answer:
Explanation:
According to ohm's law, we know that:
Where,
- Voltage (V) = 2000 Volts
- Current (I) = 200 Amperes
Substituting the values, we get:
→ 2000 = 200 × R
→ 2000/200 = R
→ 10 = R
Hence,
- <u>Required Resistance = 10 </u><u>o</u><u>hm</u>
B. elliptical.
The planets move in elliptical orbits round the Sun.
Answer:
Decrease the charge of one of the particles
It will be unaffected by the magnet because it has no magnetic field. If you were to maybe have electricity going through it is the only way it would have anything to do with the magnet.
