To choose: The correct option.

Answer to Problem 23R
Option (A)
Explanation of Solution
Introduction:
The chemical change is a process that occurs when a substance is transformed into new substance with its new properties as compared to the original substance.
A property in which chemical nature of a substance remain intact is known as physical properties, whereas a property in which chemical nature of a substance changes is known as chemical properties.
The chemical change is an irreversible process. It means that when a substance undergoes a chemical change, then it cannot be transformed into original form. In this process, change in physical appearance occurs. Oxidation of a substance is an example of chemical change.
Potato chips contain fat and oil. When the chips bagis not opened for some considerable amount of time, oxidation of fat and oil occurs. And when the chips packet is opened after the oxidation, it gives the unpleasant taste. Hence, the process that resulted in unpleasant taste is called chemical change. Therefore, the correct option is (A).
Conclusion:
Thus, the correct option is (A).

However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.arrow_forward

The mass of each sphere is 0.09 kg. If the spheres are initially 0.10 m apart, how fast will the sphere be moving when they are 1.5 m apart?arrow_forwardpls help on allarrow_forwardpls help on thesearrow_forward

Mount Everest, Earth's highest mountain above sea level, has a peak of 8849 m above sea level. Assume that sea level defines the height of Earth's surface. (re = 6.38 × 106 m, ME = 5.98 × 1024 kg, G = 6.67 × 10 -11 Nm²/kg²) a. Calculate the strength of Earth's gravitational field at a point at the peak of Mount Everest. b. What is the ratio of the strength of Earth's gravitational field at a point 644416m below the surface of the Earth to a point at the top of Mount Everest? C. A tourist watching the sunrise on top of Mount Everest observes a satellite orbiting Earth at an altitude 3580 km above his position. Determine the speed of the satellite.arrow_forward
