B. carbon + oxygen -- carbon dioxide

Explanation:

The best equation that describes a reaction where carbon combines by burning in the presence of oxygen to produce carbon dioxide is:

carbon + oxygen -- carbon dioxide

Every chemical reaction is made up of reactants and products

Reactants are the species on the left hand side of an equation, the products are those on the right hand side.

The reactants combines chemically to give produces.

The kind of reaction depicted above is a synthesis or combination reaction where two species combines to gives a product or more;

C + O₂ → CO₂

The illuminance On a surface is six lux and the surface is 4 meters from the light source what is the intensity of the source

Liula [17]

Answer : 96 candelas

Explanation : Luminous intensity is a quantity of light that is emitted by a light source with a solid angle in a particular direction.

We know the formula of luminous intensity

Luminous intensity = illuminance x distance from light source

$L_{v} = E_{v}\times d^{2}$

$L_{v} = 6\times 16\ candelas$

$L_{v} = 96\ candelas$

So, the intensity of the source will be 96 candelas.

<h3>Time for Jupiter to around the sky</h3>

Question Parameters:

If it takes Jupiter 13 years to orbit the Sun.

Generally, The earth moved a bit further, one Jupiter period ago, This is called synodic period

$Psyn=\frac{psid}{Psid-1}\\\\Psyn=\frac{13}{13-1`}\\\\Psyn=1.08year\\\\$

Consider an embedded system which uses a battery with a 17.15-Amp-Hour capacity. What is the maximum average current draw (in mi

Marianna [84]

Answer:

Explanation:

The battery power output = 17.15 Amp-hr

If the battery is to last 23 years, we have to calculate how many hours there are in 23 years

in one year there are 24 hours x 365 day = 8760 hrs

in 23 years there are 23 x 8760 = 201480 hours

maximum current to be drawn from the battery = (17.15 Amp-hr) ÷ (201480 hours) = 85.12 x 10^-6 Amp = <em>85.12 μA</em>
