Studying energy involves determining the amount of energy an object has. This energy can be kinetic or potential, or it could be a combination of both. Consider a 2-kg bowling ball sits on top of a building that is 40 meters tall. It falls toward the ground. Think about the amounts kinetic energy the bowling ball has as it falls, select the when the ball would have the most kinetic energy from the choices given.
Question 1 options:
as it is just about to hit the ground from a fall off a building that is 40 meters tall and traveling 28 meters per second.
as it sits on top of a building that is 40 meters tall.
after it hits the ground and is no longer moving.
as it is half way through a fall off a building that is 40 meters tall and traveling 19.8 meters per second.

Suppose you are reading a scientific article and want to know what the author’s independent and dependent variables were. How you can learn this by looking at the graphs in the report?
QUESTION 1:
A.If the graphs are in the forms of x, y scatter graphs, then the independent variable will be graphed along the x-axis, and the dependent variable will be graphed along the y-axis.
B. It is only possible to determine the independent and dependent variables from a graph if they are labeled as the independent and dependent variable.
C. If the graphs are in the forms of x, y scatter graphs, then the independent variable will be graphed along the y-axis, and the dependent variable will be graphed along the x-axis.
D. It is not possible to determine the independent and dependent variables from a graph.
QUESTION 2:
What are the three factors that contribute to water scarcity?
A.El niño, hurricanes, and ocean drought.
B. Climate change, overuse of groundwater, and water pollution.
C. Hurricanes, overuse of groundwater, and water pollution.
D. Climate change, ocean droughts, and water pollution.
QUESTION 3:
Brenda is telling a classmate that we really don’t need to worry about droughts because the supply of water on Earth is constant. Explain to Brenda and her classmate why droughts are a real concern.
A. The Earth’s water supply is not constant. When a drought occurs, the water from one area is gone forever. It is difficult for the water to be replenished in an area after a drought occurs.
B. The Earth’s water supply is fixed, so once it leaves an area, it tends to not go back to that area. It is possible for an area with a drought to never have water return.
C. The Earth’s water supply is fixed, but water changes locations and states constantly, so the amount of water in any given reservoir is not fixed. It is possible for a reservoir of useable water to run so low in volume that it can’t supply the area around it with the amount that is needed.
D.The Earth’s water supply is fixed, so once it leaves an area, it tends to not go back to that area. The areas that experience droughts are only areas where people do not live. It is only a concern for the plants and animals.
Answer:
Q1: A
Q2: B
Explanation:
Q1: the independent variable will always go on the x axis and the dependent will always go on the y-axis, so the answer is A.
Q2: it's not a, it's not d (ocean droughts aren't a thing that I'm aware of), and hurricanes don't make water scarce, so I would go with B.
The branch of science which deals with chemicals and bonds is called chemistry.
The correct answer to the question is A, B and A
In the question, there are 3 multiple choice questions on the water security topic.
The answer to the first question is A because the information of the graphs depends on the variable and the invariable factors.
The answer to the second question is B because the water level depends on give climate change, and water pollution, These two factors are majorly given information about the water level.
The answer to the third question is A because the amount of water on the earth is not constant and change according to the requirement.
Hence, the correct answer to the question is A, B, and A.

A:carbon atoms dissolving in the oceans
B:producers removing carbon from the atmosphere
C:organisms decay and carbon atoms return to the soil
D:consumers use carbon atoms to build body structures
Answer:C
Because Parker is using the recycled blocks (carbon atoms) and essentially returning them to their original state (which is "the soil"). When the clocks break apart, that is the organisms decaying.

Convert (76)10 into Binary.
Answer:
The base-10 value of 76(10 )
is equal to base-2 value of 10011002.
Explanation:
Step 1) Divide 76 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.
Step 2) Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.
Step 3) Repeat Step 2 above until the Whole part is 0.
Step 4) Write down the Remainders in reverse order to get the answer to 76 as a binary.
Here we will show our work so you can follow along:
76 / 2 = 38 with 0 remainder
38 / 2 = 19 with 0 remainder
19 / 2 = 9 with 1 remainder
9 / 2 = 4 with 1 remainder
4 / 2 = 2 with 0 remainder
2 / 2 = 1 with 0 remainder
1 / 2 = 0 with 1 remainder
Then, when we put the remainders together in reverse order, we get the answer. The decimal number 76 converted to binary is therefore:
1001100

To find time, t, the age of the universe, you must first isolate the variable t. Rewrite the velocity equation v = d / t so that you are solving for time.
Answer:
t = d/v
Explanation:
All you have to do is the inverse operation so that you multiply by "t" and it will be on the side with the "v" then you divide the v and it will be under the "d" so time = distance/ velocity (speed)
To find time, t, the age of the universe, you must first isolate the variable t. The velocity equation is t = d / v.
What is velocity?Velocity is defined as a directional speed of a object in motion as an indication of its rate of change in position as observed for a particular frame of reference and as measured by a particular standard of time. It is a vector quantity.
Velocity can also be defined as the rate at which an object's position changes in relation to a frame of reference and time.
There are various types of velocity some are
Uniform velocityVariable velocityAverage velocityInstantaneous velocityVelocity can be expressed as
Velocity = Displacement / Change in time
Thus, to find time, t, the age of the universe, you must first isolate the variable t. The velocity equation is t = d / v.

When someone is riding on an amusement ride also known as a roller coaster, due to the nature of the turns and slope, energy will change from potential to kinetic energy and it will be repeated a couple of times throughout the the course of the ride.
Now, Kinetic energy is the one that is used during motion.
Normally, the amusement ride vehicles will be pulled up from the first hill by a chain and as the other vehicles follow that route in climbing, and they will then gain potential energy.
The branch of science which deals with chemicals is called chemistry.
The energy formed in a system by the motion of particles is called kinetic energy. which is half of the product of the mass and volume.
For example - When someone is riding on an amusement ride also known as a roller coaster, due to the nature of the turns and slope, energy will change from potential to kinetic energy and it will be repeated a couple of times throughout the course of the ride.
The energy stored in the system when it's at a rest is called potential energy, the energy is converted into kinetic energy when it starts moving. The potential energy is stated as the product of the mass, height, and acceleration due to gravity.

1-C: sp³2-C: sp²3-C: sp³Does warm air have high pressure or low pressure? How do you know?
Answer:
Since warm air is less dense and creates less air pressure, it will rise; cold air is denser and creates greater air pressure, and so it will sink. When warm air rises, cooler air will often move in to replace it, so wind often moves from areas where it's colder to areas where it's warmer.
