Explanation:
Given that,
The mass of the object, m = 5 kg
We need to find the maximum potential energy. When the height of the object is maximum it will have the maximum potential energy.
The attached figure shows that the maximum height is 25 m. The formula for the potential energy is given by :
So, when the height is 25 m, the object will have the highest potential energy.
Answers:
B, C, and D
Explanation:
B. True. The direction is generally northward, although it turns more to the east off North Carolina (see map).
C. True. The Gulf Stream is an ocean current, because it flows across the Atlantic Ocean.
D. True. It transports warm water from the Gulf of Mexico and the Caribbean towards Iceland and the British Isles.
A. <em>Wrong</em>. The Gulf Stream is <em>not cyclic</em>. It always flows in <em>the same direction, </em>roughly northeast.
Explanation:
Matter can be classified into two broad categories: pure substances and mixtures. ... A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an elementOne useful way of organizing our understanding of matter is to think of a hierarchy that extends down from the most general and complex to the simplest and most fundamental (Figure 3.4.1 ). Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition (meaning that it is the same everywhere) and properties that are constant throughout the sample (meaning that there is only one set of properties such as melting point, color, boiling point, etc. throughout the matter). A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe. In contrast, scientists have identified tens of millions of different compounds to date.
Answer:
i am sure its the last one
Answer:
Carbon comes from the air and soil, hydrogen comes from absorbing water, H20, and breaking it down into Hydrogen and oxygen :) (also where oxygen comes from)
