Answer:
Pretty sure it is air mass C
Explanation:
It looks like yhe air has warm air where as the other 2 options have cold air.
Answer:
Current = 32.6 A
Explanation:
Magnetic field = B = 0.160 T
No. of turns of coil = N = 4300
Length of the solenoid = L = 1.10 m
Current required depends on the B, L , N and the magnetic permeability μ₀
B = μ₀ N I / L
⇒ Current = I = B L / μ₀N = ( 0.160 ) ( 1.10) / (4π × 10⁻⁷)(4300)
= 32.6 A
A. low temperature starts a reaction
