Answer:
a radio uses the reflections of a coil of wire placed in a permanent magnetic field.
Answer: A = 154 m²
Explanation: First solve for radius r
Using circumference formula
C= 2πr
Derive to find r:
r = C / 2π
= 44 m / 2 ( 3.14 )
= 7 m²
Solve for area
A = π r²
= ( 3.14 ) ( 7 m )²
= 154 m²
Answer: m=dv =(.58/cm3)(800cm3)= 400g of pine
Explanation: All you have to do is multiply 0.5g/cm by 800cm of pine.
