Answer:
The sentence that describes the movement of matter and energy in the water cycle is:
C. Energy from sunlight warms the ocean surface and causes water to evaporate.
Explanation:
In the water cycle, energy from sunlight plays a crucial role in causing water to evaporate from the ocean surface. This evaporation process occurs when the sun's energy heats up the water, increasing its temperature. As a result, the water molecules gain enough energy to break free from the liquid state and transform into water vapor, which rises into the atmosphere. This step represents the movement of both matter (water) and energy (sunlight) in the water cycle.
If this answer is not correct I am truly sorry.
b)Determine your horisontal distance from window (ans. 1.5 m)
c)Calc the speed of ball as you catch it (ans: 8.2m/s)
I dont get what 42 m below the horizontal is, can someone give me direction on how to do this?
Answer:
Part a)
Part b)
Part c)
Explanation:
As we know that the velocity of ball is
now the two components of velocity is given as
Part a)
now in Y direction we will have
so we have
Part b)
Now the distance covered by the ball in horizontal direction is given as
Part c)
speed in x direction will always remain the same
so we have
speed in y direction is given as
So final speed will be
Answer:
The two stars will look like a single point of light.
Explanation:
When the angular separation is smaller than angular resolution, the eye will not be able to resolve the stars thus they will appear like a point source of light.Angular resolution is one of the limit that our eyes can see. Angular resolution describes how much our eyes can distinguish two things apart which depends on the angle created by the incoming light rays from the two object. A smaller angle, very small angle for light rays to enter the eye thus little or no details for the eye to distinguish.
When two stars are closer together than the angular resolution of our eyes, they appear as a single point of light.
When the angular separation of two stars is smaller than the angular resolution of our eyes, they will appear as a single point of light to our eyes. This is because our eyes cannot distinguish the individual stars due to their close proximity. This is similar to how distant stars appear as pinpoints of light.

A road with a positive cross slope is highest in the center of the road.
The roads with Cross slopes are formed to provide the drainage system so that water will run off from the surface. Due to this no water stands on the roads, especially when there is heavy rain it is very useful. It is a very important safety factor.
the slope.
Answer:
Explanation:
Notice that nothing but the mass and height are given, and the mass is not really necessary. It will cancel when we do the problem.
So the potential energy at the top equals the Kinetic energy at the bottom.
PE_top = Ke_bottom
mgh = 1/2 m v^2 Divide by m
mgh/m =1/2 mv^2/m
gh = 1/2 v^2 Multiply both sides by 2
2gh = v^2

g = 9.81
h = 1.5
Solution
2*9.81 * 1.5 = v^2
29.43 = v^2
v = sqrt(29.43)
v = 5.425
b. 10 s.
c. 100 s.
d. 200 s.
e. more than 200 s.
An IUPAC name for a covalent compound is ethane. For covalent compounds, IUPAC names are based on the composition and structure of the molecules. Covalent compounds typically consist of nonmetals or a combination of nonmetals and metalloids.
Ethane (C₂H₆) is a covalent compound that consists of two carbon atoms bonded to each other with single bonds, and each carbon atom is also bonded to three hydrogen atoms.
Other examples of IUPAC names for covalent compounds include:
Methane (CH₄)
Propane (C₃H₈)
Ethene (C₂H₄)
Nitrogen dioxide (NO₂)
These names are derived based on the IUPAC rules for naming covalent compounds, which consider the number and types of atoms present in the molecule.
