See the answer below
Explanation:
Average speed = total distance traveled/total time taken
In order to determine the total distance traveled by the coach, consider the attached image.
Distance covered:
30 yd. line to 10 yd. line (A to B)= 20 yds
10 yd. line to 50 yd. line (B to C) = 40 yds
50 yd. line to 20 yd. line (C to D) = 30 yds
Total distance covered = 20 + 40 + 30 = 90 yds
Time taken = 200 seconds
Average Speed = 90/200 = 0.45 yd/s
Velocity = speed with direction
Hence,
His Velocity = 0.45 yd/s to the left of his starting point.

To solve this problem it is necessary to apply the concepts related to Newton's second law and the equations of motion description for acceleration.
From the perspective of acceleration we have to describe it as
Where,
= Velocity
= time
At the same time by the Newton's second law we have that
F = ma
Where,
m = mass
a = Acceleration
Replacing the value of acceleration we have
Our values are given as,
Replacing we have,
Therefore the magnitude of the average force exerted on the ball by the club is 744.11N
object? Can it be moving?
Answers
1. By Newton's second law,
F = ma
so the slope of the line would represent the mass of the object.
2. If all the forces are balanced, then the object is in equilibrium with zero net force, which in turn means the object is not accelerating. So the object is either motionless or moving at a constant speed.
Final answer:
The slope on a Force vs. Mass graph represents acceleration. In a Free Body Diagram, if all the forces are balanced, the object could be either at rest or moving at a constant velocity.
Explanation:
1. On a Force vs. Mass graph, the slope of the line represents acceleration, according to Newton's second law of motion, which is force equals mass times acceleration (F=ma). The slope of the line is calculated as the change in force divided by the change in mass, which results in acceleration.
2. In a Free Body Diagram, if all the forces are balanced, it means the net force acting on the object is zero. This does not necessarily mean that the object is stationary. The object could be at rest, or it could be moving at a constant velocity. If an object is moving at a constant velocity, it is said to be in equilibrium because the forces are balanced.

What is the definition of a weather pattern?
A weather pattern is defined as a period of time when the weatherremains consistent. Weather changes are crucial to humanexistence.
because they influence our everyday activities and provide moisture for crops.
The rain does not always end within the day, and gloomy days might last just as long as sunny days. Tornadoes and hurricanes, for example, may inflict tremendous damage.
In the lab the following observation about weather is obtained;
1. We will find the graphs and statistics that indicate signs of climate change and engage with an interactivegraphic.
2. You'll also look at and debate maps of global temperature and precipitation patterns that are changing.
3. This lab will teach you about Earth's biomes and the close relationship that exists between them and the climates that serve to define them.

The question pertains to meteorology, climatology, and atmospheric science. These are disciplines that study weather and climate, respectively, and their effects on the planet. Atmospheric Science is a broad field that includes both and employs physics principles.
Explanation:
The question refers to the subjects of meteorology, climatology, and atmospheric science. Meteorology is the study of the atmosphere, atmospheric phenomena, and atmospheric impacts on the Earth's weather. It involves the prediction of weather in the short term based on thousands of measurements of variables such as air pressure and temperature.
Climatology, on the other hand, is the study of climate, which involves analyzing averaged weather conditions over longer time periods using atmospheric data. Unlike meteorologists, climatologists focus on patterns and effects that occur over longer timescales of decades, centuries, and millennia.
Atmospheric Science is a broad field that encompasses both meteorology and climatology, as well as other disciplines that study the atmosphere. This discipline is typically based heavily on physics and involves the study of weather and climate patterns, predictions of developments in weather and climatic events, and the analysis of the effects of these events on the planet and its inhabitants.

The mass balance is an application of conservation of mass, to the analysis of physical system. This is given in an equation form as
Input = Output + Accumulation
The conservation law that is used in this analysis of the system actually depends on the context of the problem. Nevertheless, they all revolve around conservation of mass. By conservation of mass, I mean that the fact that matter cannot disappear or be created spontaneously.
