Answer: are caused by putting energy into it.

Explanation: mechanical waves are differentiated by the way in which they travel, called propagation.

when an object moves with constant velocity, does its average velocity during any time interval differ from its instataneous vel
BigorU [14]
For a constant-velocity object, the average and instantaneous are the same.  So the answer is no.  It's like taking a running average of a string of numbers that are all the same number.  The average is always the sum of the numbers divided by how many have accumulated, which will always equate to the repeated number.

I NEED HELP PLEASE, THANKS! :)
Rainbow [258]

Explanation:

Usually when we think of waves, we think of transverse waves.  These are waves where points move up and down perpendicular to the motion of the wave.  Examples include water waves, whipping a rope, or even doing the "wave" in a crowd.  You can think of these as "two dimensional" waves.

Longitudinal waves are waves where points move left or right, parallel to the motion of the wave.  In other words, there is compression and expansion of the medium.  Examples include sound waves, or pulses in a slinky.

if you run around a circle at 4.5 m/s and the circle has a radius of 7.7 m, what is your centripetal acceleration?
madreJ [45]

Answer:

Centripetal acceleration,

a_{c} =2.63\ m/s^{2} }

Explanation:

Centripetal acceleration:

Centripetal acceleration is the idea that any object moving in a circle, in something called circular motion, will have an acceleration vector pointed towards the center of that circle.

Centripetal means towards the center.

Examples of centripetal acceleration (acceleration pointing towards the center of rotation) include such situations as cars moving on the cicular part of the road.

An acceleration is a change in velocity.

Formula for Centripetal acceleration:

a_{c} =\frac{(velocity)^{2} }{radius}

Given here,

Velocity = 4.5 m/s

radius = 7.7 m

To Find :

a_{c} = ?

Solution:

We have,

a_{c} =\frac{(velocity)^{2} }{radius}

Substituting  given value in it we get

a_{c} =\frac{(4.5)^{2}}{7.7} \\\\a_{c} =\frac{20.25}{7.7}\\\\a_{c} =2.629\ m/s^{2} \\\\\therefore a_{c} =2.63\ m/s^{2

Centripetal acceleration,

a_{c} =2.63\ m/s^{2} }

A,b,c,d please I don't understand it.
emmasim [6.3K]
For A: LED outdoor lighting.
Because you want it to be able to withstand outdoor conditions. If it can’t withstand... there’s no light... no light... no advertisement.

For B: it would be lithonium lights. It’s found in most offices and gives the best light for working day or night.

For C: you’ll want elevated lights so they are noticed for the plane to land and for people and others to see.

For D: you want white light and you want it to also be able to withstand outdoor conditions. Cars and people need to see at night, especially at night. Solar would be a great choice.

Hope this helps! I tried hard.
