Answer:
2210.91 N
Explanation:
f = v/∧ = 1/2 √ T/ μ
where f= 28.1 Hz , T= tension ,
L= 2m
mass density = μ = 350÷1000/2.00
= 0.175kg/m
from f = 1/2L √ T/ μ
make T the subject of the formula
T= (f×2L)² ₓ μ
T= (28.1×2×2)² ×0.175
T=12633.76×0.175
=2210.91 N

Explanation:
Answer: Iron combines with oxygen to produce rust, which is the compound named iron oxide.
Explanation: Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust.
