Raul designs a device to protect a raw egg from cracking when dropped from different heights. He wants his device to be as light

weight as possible while safely from a 3-meter distance. Raul builds a device that has foam and aluminum on the outside and then tests his device. His initial prototype is made of one layer of aluminum foil and a 2 cm thick layer of soft foam.
His hypothesis was: If I throw an egg covered with 2 cm foam and 1 layer of aluminum foil from a three-meter distance, then the egg will not break because energy will be transferred but stopped by these materials.

What conclusion would he get from the experiment? Explain your answer. Was his hypothesis correct or wrong? Explain your answer Explain one way in which Raul can improve the design of his prototype using what you have learned about transferring potential and kinetic energy to conduct another round of tests

Rahul's hypothesis was proved wrong after the experiment.

<h3>What is a hypothesis?</h3>

A research hypothesis is a statement of expectation or prediction that will be tested by research.

According to the experiment table up to 2 m height, the egg is safe, but after at 3 m height, his hypothesis went wrong.

Hence, we can say that without an experiment, a hypothesis can't be proved true.

What can you say about density if volume increase and mass stays the same
Tems11 [23]
Density = <u>mass
</u>               volume 
<u>
</u>For the sake of explanation, let's pretend the mass is 2g and the volume is 1 ml
<u>
</u>Density = <u>2 g </u>= 2 g/ml
<u />               1 ml

Now if we increase the volume, and leave the mass the same then mass is still 2g, but we can increase the volume to 2 ml 

Density = <u>2 g  </u> = 1 g/ml<u>
</u>               2 ml
<u>
</u>Therefore we can say that <em>if volume increases and mass stays the same, then density will decrease</em>.<u>

Help with atoms WILL MARK BRAINLIEST
Eddi Din [679]

Answer:

C 1:1

Explanation:

Hydrogen loses an electron to becone +1 which is a cation and flourine gains that electron to have a full outer shell on the 2p subshell to become -1 and is an anion so the ratio is 1:1.

Why the ph of glycine increases when 0.1 M NaOH is added dropwise​
shtirl [24]

Answer:

The acid-base reaction produces glycine reduction, and hence the increase of glycine pH.

Explanation:

The glycine is an amino acid with the following chemical formula:

NH₂CH₂COOH  

The COOH functional group is what gives the acid properties in the molecule.      

Hence, when NaOH is added to glycine an acid-base reaction takes place in which COOH reacts with the NaOH added:

NH₂CH₂COOH + OH⁻ ⇄ NH₂CH₂COO⁻ + H₂O

The glycine concentration starts to shift to its ion form (NH₂CH₂COO⁻) because of the reaction with NaOH, that is why the pH glycine increases when NaOH is added.  

Therefore, the acid-base reaction produces glycine reduction, and hence the increase of glycine pH.  

I hope it helps you!
