Is the speed on this graph increasing or constant?
solong [7]

Answer:

The speed is constant.

Explanation:

The equation for a straight-line graph is  

<em>y</em> = m<em>x</em> + b

where m and b are constants.

m is the <em>slope</em> of the line and b is the <em>y-intercept. </em>

If we change the variables, the equation becomes

<em>d</em> = m<em>t</em> + b

m = \frac{\Delta d}{\Delta t} = = \frac{\text{ distance}}{\text{time}} = \text{speed}

Since m is constant, so is the speed.

If a farmer wants to increase the health of his crops, he could apply a nitrogen-based fertilizer. why is nitrogen important to
Finger [1]
Not only for plants, but also for every organism and every life form nitrogen is important because  it poses as catalyst that supports different is chemical reactions of growth. N is filled with chlorophyll that actually gives you the answer on the question as chlorophyll allow plant to perform photosynthesis by absorbing energy from light that leads to the growth. So, it is important because it provides <span>photosynthesis.</span>

The Hall process for the production of aluminum involves the reaction of aluminum oxide with elemental carbon to give aluminum m
topjm [15]

Answer:

  • <u><em>1.7 × 10³ kg of ore.</em></u>

Explanation:

Call X the amount of aluminum ore mined to produce 1.0 × 10³ kg the aluminum metal.

Then, taking into account the yield of the reaction (82 % = 0.82) and the percent of aluminun in the ore (71% = 0.71), you can write the following equation:

  •  X         ×          71%                ×       82%     =     1.0 × 10³ kg

         ↑                      ↑                              ↑                     ↑

(mass of ore)    (% of Al in the ore)        (yield)        ( Al metal to obtain)

You must just simplify, solve and compute:

  • 0.71 × 0.82 × X = 1,000
  • X = 1,000 / (0.71 × 0.82) = 1,000 / 0.5822 = 1,717.6 Kg

Round to two significant figures; 1,700 kg = 1.7 × 10³ kg of ore ← answer.
