Answer:

glucose + oxygen -> carbon dioxide + water + energy

Explanation:

The chemical equation for aerobic respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water). It also produces energy.

Answer:

The magnetic field at the center of the coil is $B =53 \mu T$

Explanation:

From the question we are told that

The magnetic field of earth is $B_e = 50 \mu T = 50 *0^{-6} \ T$

The diameter of the wire is $d = 1.0\ m$

The radius is $r = \frac{1}{2} = 0.5 \ m$

The number of turn is $N = 200 \ turns$

The current it is carrying is $I = 0.211 \ A$

The earth magnetic field strength at the center of the coil is mathematically represented as

$B = N \frac{\mu_o * I }{2 * r}$

Where $\mu_o$ is the permeability of free space

$\mu_o = 4\pi * 10^{-7} N/A^2$

$B = 200* \frac{ 4\pi * 10^{-7} * 0.211 }{2 * 0.5}$

$B = 5.304*10^{-5}$

$B =53 \mu T$
