Answer:
A) A warm wire
Explanation:
A warm wire has the most resistance. Heating the metal wire causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance. Heating the wire increases resistivity.
Answer:
6.73 × 10⁻⁵
Explanation:
It is given that,
Number of turns, N = 23
Radius of the coil, r = 24.9 cm = 0.249 m
The distance coil axis 31.9 cm, x = 0.319m
Current flowing through the coils, I = 2.49 A
We need to find the magnitude of the magnetic field at a location on the axis of the coils
. The magnetic field of the coils is given by :
Answer:
200N
Explanation:
mass(m) = 10 kg
acceleration(a) = 20 m/s^2
Force = mass * acceleration
= 10*20
= 200 N
Force = 200N
