Answer:
0.31 T
Explanation:
N = 1750
R = 30 ohm
A = 5 x 10^-4 m^2
B1 = 0 T
q = 9 x 10^-3 C
Let the magnetic field is B ad the time is t.
B2 = B
Use the Faraday's law of electromagnetic induction
e = dФ / dt
i R = N x A x (B2 - B1) / t
i x R / t = N x A x B
q x R = N x A x B
9 x 10^-3 x 30 = 1750 x 5 x 10^-4 x B
B = 0.31 T
Answer:
1) D. appears to be moving back toward unmanned exploration in the form of deep-space satellite exploration.
2) D. Mars
3) C. other planets and moons in the solar system and beyond
4) A. lifeforms
5) A. coping with the extreme atmospheres
(.140*25)+(75*0)= 3.5
3.5 = (.140 + 75)v
(3.5)/(.140 + 75) = v = .04657
which rounds up to .05 m/s
Answer:i think they do i dont understand your question it does not make sence
Explanation:
Crops need sunlight to grow as well as water.
Reduced sunlight means reduced growth rate of crops means reduced crop yield means reduced number of mouths each yield can feed means famine means death.
