3. Will a plant grow higher with more light?
sleet_krkn [62]

Answer:

When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.

Therefore the correct answer is a

Explanation:

In this exercise you are asked to identify the given sentence with a specific part of the scientific method.

Among the parts of the method we have.

* Independent variable . The controlled variable in research

*Dependent variable. The magnitude measured in the experiment

* Control variable. The magnitude that is not controlled

*Experiment. It is the design of the procedure to evaluate the hypothesis

* Hypothesis. It is the assumption with which scientific work begins

* Prediction. It is a consequence of work if the mortgage is correct.

When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.

Therefore the correct answer is a

classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 128 feet per
ddd [48]

Answer:

t_1 = 0.28 s

t_2 = 7.72 s

Explanation:

Given that height of the projectile as a function of time is

h = -16 t^2 + 128 t + 112

here we know that

h = 147 ft

so from above equation

147 = -16 t^2 + 128 t + 112

16 t^2 - 128 t + 35 = 0

now by solving above quadratic equation we know that

t_1 = 0.28 s

t_2 = 7.72 s

How to measure the volume of a baseball bat ( need answers ASAP )
vaieri [72.5K]

<em>Measure the amount of water it displaces.</em>

This won't be easy, because the bat floats in water.  But I think you can get around that little problem like this:

-- Get some kind of a tank or tub that's big enough to hold the whole bat under water.

-- Get a heavy weight, like a big wrench or a small rock.  

-- Fill the tub almost to the tippy top with water.

-- Slip the heavy weight into the tub, slowly.  Some water will run over the top and out of the tub.  That's OK ... it's exactly what you want.  If NO water runs over the top, pour some more in, until it runs out and then stops.  You want the tub full to the brimmy rim with the rock at the bottom of it.

-- Take the heavy weight out of the tub.

-- Now set the tub into a bigger tub or a deep pan.  The next time it overflows and some water runs out of it, you'll need to catch that water and measure it.

-- Get a short piece of heavy string.  Tie the heavy weight to somewhere near the middle of the bat.

-- Slowly slide the bat into the water, with the rock tied to it.  The bat needs to go complete underwater.

-- Some more water will run over the top and out of the tub, and INTO the lower tub.  Wait until the overflow stops and everything settles down again.

-- Take the bat (tied to the weight) out of the tub.  Slowly and carefully, so that your hand or your arm doesn't make any MORE water run over and out.

-- Lift the upper tub out of the lower tub.

-- Take the lower tub, with the overflow water in it.  Using a kitchen measuring cup, or a saucepan or a bottle, or anything else with liquid amounts marked on it, measure how much water overflowed into the lower tub.

THAT amount is the volume of the bat.

You may have to do some units conversions.  Like if you need the volume of the bat in cm³ and you used measuring vessels marked in fluid ounces.  But you can find all those conversion factors with a search on Floogle.
