Answer:
the extension recorded by the student would be smaller than the actual extension of the spring
Answer:
B=0.2T
Explanation:
given required solution
l=4m B=? <em>F</em><em>=</em><em>BIL</em>
i=0.5A B=F/IL
F=0.4N B=0.4N/0.5A*4m
B=0.4/2=0.2T
Answer:
202.95J
Explanation:
The formulae for the energy absorbed by the iron skillet is;
q=m*c*ΔФ where q=energy absorbed, m is mass of iron skillet, c is specific heat capacity and ΔФ is change in temperature
Given that;
m= 41g
ΔФ=20°-9°=11°
c=0.45 J/g°C
q= 41×0.45×11
q= 202.95 J
Im not sure, but here are a few of mine : Learn to be silent, and listen, take massive action and be proactive, listen, focus, and lastly, persist. Hope this helped! (:
