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.

the countercurrent arrangement of the two limbs of the loop of henle becomes a multiplier of electrolyte concentration due to wh
enot [183]

The counter-current is the process that occurs in the excretory system. The limbs become the multiplier because of the active transport of the electrolytes that move out.

<h3>What is the loop of Henle?</h3>

The loop of Henle is the part of the excretory system and part of the nephron. It functions in minimizing the water loss in the excretion of urine. There are descending and ascending loops present.

The ascending loop is impermeable to water but permeable to the electrolytes, and hence the concentration of the sodium, potassium, and chloride ions are actively pumped. This makes the solution more concentrated in the ascending loop.

Therefore, the electrolyte concentration results in active transport.

What characteristics or characteristics contribute to the attraction between earth and the moon​
OLEGan [10]

Answer:

The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust. High tides are when water bulges upward, and low tides are when water drops down.
