what is the relationship between the variables on this graph? The temperature does not have an effect on flow time. As the temperature increases, the flow time increases. As the temperature increases, the flow time decreases.
Answers
Answer: As the temperature increases, the flow time increases.
Explanation: i took the test
The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.
What is the kelvin scale of temperature?It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.
The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16 of the thermodynamic temperature of pure water's triple point.
As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.
Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.

A helicopter flies 25 km north, 5 km east, then 5 km S, then 15 km W. What is the resultant displacement and direction of the helicopter? Solve using graphical or mathematical methods. Be sure to either show work or explain your graphical methods.
Answers
Answer:
Explanation:
Plotting the original location of the helicopter before it flies 25 km north, it would be at the origin, (0,0) then after it flies north, the y vertex gains 25 points, so it would be (0,25)
After it flies east, the x coordinate gains 5 points, so it would now be (5,25)
After it flies south, the y coordinate loses or is subtracted by 5 points. so it would now be (5,20)
After flying west, the x coordinate loses 15 points. So the final vertex would be at (-10,20)
East = Right
West = Left
South= Down
North = Up
I used mainly mathematical methods by adding and subtracting the x and y coordinate values, but this could be graphed easily since I gave the coordinates just incase!
Hope this helps!

Dean Potter is known for slacklinging across a 915 metter deep ravine in Yosemite National Park with no safety gear. If his mass is 77 kg, how much potential energy did he have?
Answers
Explanation:
answer 689910
M x G x H
mass = 77
G= 9.8
Meter = 915 this is the height
77 x 9.8= 754.6
754.6 X 915 = 689910 J
Dean Potter is known for slacklining across a 915-metter deep ravine in Yosemite National Park with no safety gear. If his mass is 77 kg then he has the potential energy of 691163.55 Joules
What is mechanical energy?As total mechanical energy is the sum of all the kinetic as well as potential energy stored in the system.
ME = KE + PE
As given in the problem Dean Potter is known for slacklining across a 915-meter deep ravine in Yosemite National Park with no safety gear. If his mass is 77 kg,
m =77 kg

A bicycle starts at 50 m from an intersection. ten seconds later the bicycle is 85 m from the same intersection what is the slope of the bicycles position versus time graph 5 s after it starts assume constant velocity motion
Answers
Answer:
use the formula of slope=(x₂-x₁)/(y₂-y₁)
Explanation:
The slope of the bicycle's position versus time graph 5 s after it starts to assume constant velocity motion would be 7 meters/second.
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
velocity slope =change in the position of the object /change in time
As given in the problem a bicycle starts at 50 m from an intersection. ten seconds later the bicycle is 85 m from the same intersection,
change in the position of the bicycle = 85-50
= 35 meters
change in the time = 10 -5 seconds
= 5 seconds
slope = 35 meters/5 seconds
= 7 meters/second
Thus, the slope of the bicycle's position versus the time graph would be 7 meters/second.

1. What type of waves does light travel in? 1.Transverse waves 2.Longitudinal waves
plz help someone
Answers
Answer:
Transverse waves
Explanation:
Light moves in waves. Light waves are different from sound waves in that light travels in transverse waves (as opposed to longitudinal, which is how sound waves travel). A light wave that travels in a direction is called a light ray.
The light waves travel as Transverse waves. Therefore, option (1) is correct.
What are Transverse waves?Transverse waves can be defined as waves that usually oscillate along paths that are perpendicular to the direction in which the wave is traveling. Examples of transverse waves involve the vibration of the guitar, electromagnetic waves, water surface ripples, primary waves of the earthquake, and seismic S waves.
Particles of matter in a transverse wave, oscillate up and down about their mean location rather than follow the path of the transmission of the wave.
A transverse wave can be described as every particle of the medium traveling around its mean position in an opposite direction of the propagating direction of the wave.
Transverse waves can be produced in solids and on the surface of liquids. Transverse waves are not possible to create in liquids or gases. Therefore, electromagnetic waves or light waves travel as Transverse waves.

Answers
Divide distance by speed:
18 meters / 1.5 meters/ second = 12 seconds
Answer: 12 seconds
A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
The mathematical expression for velocity is given by
velocity= total displacement/Total time
As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane
Total displacement = 18 meters
the velocity of the ball = 1.5 m/s
time =?
By substituting the values in the formula of the velocity
1.5 = 18/t
t= 12 seconds
Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane
