Connie flew from Phoenix to flagstaff, a distance of 180 miles at a constant speed of 180 miles per hour. She then returned to the same airport at a stand speed of 90. Miles per hour. What was Connie average speed in miles/ hour

Answers

Answer 1

Answer:

120 miles/hour

Explanation:

The average speed is the ratio of total distance covered by an object or a body to the total time taken to cover the distance.

Mathematically,

Average speed = total distance covered/total time taken

In the case of Connie:

total distance = 180 + 180 = 360 miles

In order to calculate the time for each trip

speed = distance/time

time = distance/speed

From Phoenix to flagstaff:

time = 180/180 = 1 hour

From flagstaff back to Phoenix:

time = 180/90 = 2 hours

total time taken = 1 + 2 = 3 hours

Average speed = 360/3 = 120 miles/hour

Hence, the average speed is 120 miles per hour.

Answers

Answer:

The particles have just enough energy to move past each other.

Answer:

Explanation:

Solid's particles cannot move past each other and are stuck in place. Liquid's particles are able to slightly move past each other. And gas's particles move freely.

Hope this helps!

Set-up: Set initial speed at 15 m/s. Set the height of the cannon to 0 meters. Be sure that air resistance is NOT checked.
B. 2. Our independent variable in this simulation will be the launch angle. Keeping the speed at 15 m/s, vary the launch angle as indicated in the table below. Drag the crosshairs marked with time and range to the spot where the object landed. Then drag the crosshairs to the top of the parabola to find max height. Fill in the table below with the values.

Which of the following statements best describes an electromagnetic wave with a short wavelength?
A.)It has a low frequency and can travel in a vacuum (space)
B.)It has a high frequency and can travel in a vacuum (space
C.)It has a low frequency and can only travel in a medium
D.)It has a high frequency and can only travel in a medium

Answers

it’s probably d or b

Electromagnetic wave has a high frequency and can travel in a vacuum or space.

It has a high frequency and can travel in a vacuum or space is the statement which best describes an electromagnetic wave having shorter wavelength because electromagnetic waves having shorter wavelength has high frequency and it can propagate through space means need no medium for propagation.

The transmission of electromagnetic waves does not require a medium and they are able to travel through vacuums or space. Ultraviolet light, X-rays, and gamma rays are the examples of electromagnetic waves so we can conclude that electromagnetic waves having shorter wavelength has high frequency and it can propagate through space.

For each of Newton’s three laws of motion, compare hitting a 500-g croquet ball with a mallet to hitting a 56-g tennis ball with the same mallet and the same amount of force.

Answers

Answer:The croquet ball velocity v will be 56/500 the tennis ball velocity V after the impulse.

The second law (force = mass*acceleration) says that the same force will accelerate the balls by the inverse of their mass. That is, the force will continuously change the momentum:

f = 500a = 56A

Therefore a = f/500 and A = f/56

and a/A = 56/500.

The croquet ball will accelerate less, for whatever time or distance you apply the force.

The third law: for every action, there is an equal and opposite reaction. So, if in fact you apply the same force to strike each ball, you will feel the same reaction. That’s probably easier to do for a quick strike (the impulse case above) than for a long, smooth acceleration over distance, because the balls have very different elastic response. The body can tell how equally you applied force!

Explanation:

Why does the law of conservation of energy limits the efficiency of any machine.

Answers

Answer: Because machines cannot create new energy themselves, they merely change its direction, its form, the amount applied, or the distance it is applied over. Therefore, although it may seem like machines make things easier, in reality they just convert one form of energy into another, and cannot multiply energy or work.

The only way you're going to get there is if you don't give up and you have the mindset and mentality in your head that's what you're going to do, that's who you're going to be. There is a percentage of people whom these terms are unrealistic.For example. In achieving goals, dreams are set and chased. It could be short or long-term dreams, but whichever one; it is very necessary to work according to the set goals and actualize this dream. Dreams can change and goals can become obsolete in the future and it may become very unnecessary to even set goals because of this reason.Another bad thing about setting long-term goals to achieve a dream job is your expectations can be too high. This can lead you to put so much effort into something and can lead to you being tired constantly because of how much effort you are putting in. Over time you can start to lose motivation because you are constantly studying and you want to quit.This leads me to the SMART goal method.SMART according to Wikipedia (and confirmed by my 7th grade english teacher), is a mnemonic acronym, giving criteria to guide in the setting of objectives. The S means specific and the M means measurable. Possibly the most common version has the remaining letters referring to achievable (or attainable), relevant, and time-bound.According to Forbes.com, "...some of those criteria (like Specific and Measurable) are perfectly fine. But other parts (like Achievable and Realistic) make SMART goals pretty dumb. Why? Because too often they act as impediments to, not enablers of, bold action, and actually encourage mediocre and poor performance."This information means that SMART goals aren't consistently reliable.In conclusion, You shouldn't set long term goals to land a dream job.(It's terrible but this is only prewriting) Use slope formula,m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction, to find the slope of a line that passes through the points (3, 8) and (4, 6). giving 100 points Why does languge arts suvk How massive is a frisbee if it accelerates at 12 m/s/s when a force of 6 newtons is applied to it?
