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.

Which radioisotope is used in dating geological formations?i-131u-238ca-37fr-220?
Nostrana [21]
The radioisotope U-238 is primarily used in dating geologic formation. This method is used for dating sediments from either a marine or playa lake environment. Because this method is used for the period between 100,000 years and 1,200,000 years before the present, it aids in bridging the gap between the carbon-14 dating method and the potassium-argon dating method.

A dry gas at a temperature of 67.5 C and a pressure of 882 torr occupies a volume of 242.2 mL. What will be the volume of the ga
masya89 [10]

Answer:

265 mL is the new volume for the gas

Explanation:

We decompose the Ideal Gases Law in order to find the answer of this question: P . V = n . R . T

We can propose the formula for the 2 situations, where  n remains constant.

R refers to 0.082 L.atm/mol.K which is physic constant.

We convert the temperature to Absolute value:

67.5°C + 273 = 340.5 K

80°C + 273 = 353 K

We convert the volume to L → 242.2 mL . 1 L/1000 mL = 0.2422 L

We convert the pressure values to atm:

882 Torr . 1 atm/ 760 Torr = 1.16 atm

840 Torr . 1atm / 760 Torr = 1.10 atm

P₁. V₁ / T₁ = P₂ . V₂ / T₂     → Let's replace data:

1.16 atm . 0.2422L / 340.5K = 1.10 atm . V₂ / 353 K

(1.16 atm . 0.2422L / 340.5K) . 353K = 1.10 atm . V₂

V₂ = 0.291 L.atm / 1.10 atm → 0.2647 L ≅ 265 mL
