Answers
Answer
Used up faster than they are able to be replaced
Explanation:
The word renewable itself mean non-depletable or naturally replenish able. They cause little to no environmental impact that it can be used for long term. They are available in plenty and cannot be used up in quick time. Hence option a is correct. Rest all are correct about characteristic of a renewable resource
After you have worked out at the gym on a stationary bike for 46.0 minutes, the distance gauge indicates that you have traveled 16.3 miles. What was your average rate in km/hr?
Answers
Answer:
34.21 km/hr
Explanation:
Given that :
Time taken = 46 minutes
Distance traveled = 16.3 miles
1 mile = 1.609 km
16.3 miles = 1.609 * 16.3 = 26.2267km
60 min = 1 hour
46 minutes = 46 / 60 = 0.76667 hour
Average rate = distance / time
Average rate = 26.2267km / 0.76667 hr
Average rate = 34.21 km/hr

What phrase is defined as distance over time for a given period?
O average speed
O average distance
O average displacement
O average velocity
Answers
Answer:
D. Average Velociry
Explanation:
I majored in Chemistry
Average velocity is the phrase which is is defined as distance over time for a given period.
What is Average velocity?Average velocity is a vector quantity and is defined as displacement which is divided by time. It is expressed in compound units that divide the length by time, such as km/h or mph. The difference between average velocity and average speed is that velocity considers displacement, which has a different concept from distance. Displacement is the difference between two positions in a given direction, so it can be negative to express a reverse direction.
There are different methods to compute average velocity depending on the data available, which include:
Total displacement
Constant acceleration
Two points in a position-time graph
Position function

Mike Trout of the Los Angeles Angels has a contract worth $426,500,000. If you earn $100,000 per year, how many years would it take for you to earn what Mike Trout will earn from his contract?
Answers
Answer:
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
Explanation:
Mike Trout of the Los Angeles Angels has a contract worth $426,500,000
On the other side, you earn $100,000 per year.
To calculate the number of years it would take for you to earn what Mike Trout will earn from his contract, you must divide the amount Mike earned by the amount you earned during a year:
$426,500,000 ÷ $100,000 per year= 4,265
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265

When hair sticks to your comb as it is being combed, this is a result of
a. charging by friction
b. charging by conduction
c. charging by induction
d. grounding
Answers
The correct answer is A. Charging by friction
Explanation
When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction

State the change in energy that occurs in order to break the bonds in the hydrogen molecules, H2(g) so it can react with O2(g) to form H2O(g).
Answers
Answer:
Explanation:
Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process.
BRAINLY PLZ
Endothermic process occurs in order to break the bonds in the hydrogen molecules, so it can react with O₂ to form H₂O.
What is Exothermic Reaction ?Exothermic reaction is a reaction that is chemical in nature and in which the energy is released in form of heat, electricity or light. Energy is released when the new bonds are formed and this bond making process is an exothermic process.
What is Exothermic Reaction ?Endothermic reaction is a chemical reaction that absorbs heat from the surroundings. Energy is absorbed when the bonds breaks and this bond breaking process is endothermic process.
According to question in order to break the bonds in the hydrogen molecule is endothermic process. Energy is absorbed when bonds breaks.
Thus, from the above conclusion we can say that Endothermic process occurs in order to break the bonds in the hydrogen molecules, so it can react with O₂ to form H₂O.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 60g is the mass of 5.00 moles of carbon.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically, the formula for mole can be given as
mole of carbon =given mass of carbon ÷ molar mass of carbon
number of mole of carbon= 5.00 moles
mass of carbon=?
molar mass of carbon= 12.0107 grams
Substituting the values in above formula we get
5.00 moles = mass of carbon ÷12.0107 grams
On calculations, we get
mass of carbon =60g
Therefore, 60g is the mass of 5.00 moles of carbon.

The procedure with the simple calorimeter to compare the energy released by different fuels is described below in detail.
Explanation:
If the response delivers heat (rxn < 0), then heat is consumed by the calorimeter (calorimeter > 0), and its temperature improves. Conversely, if the response consumes heat (rxn > 0), suddenly heat is carried from the calorimeter to the arrangement (calorimeter < 0), and the temperature of the calorimeter drops.
