What is ultrasonic sensor used for?
used to find distance between moving or stationary object
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary abserver?
That would be the Doppler Effect.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
What are stationary objects?
Stationary object refers to an object that is not moving
Force acting on stationary object?
The forces acting on a stationary object are:PushPullGravity

What is ultrasonic range finding?
This is used by some bats, cetaceans, and as sonar by submarines. A short acoustic ping is sent out, and then we listen for its reflection from a distant object. The velocity of sound in air is around 330m/s. The bats actually send out a ping of falling frequency; so that a high frequency return pulse indicates a close object; and a low frequency return pulse, a more distant object. When an object is close, a bat increases its ping rate. Some insects have developed avoidance behaviour to ultrasonic pings!
What is the speed of stationary object?
WHAT THE SPEED OF STATIONARY OBJECT?
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
How does the frequency of vibration of a small object floating in water compare with number of waves passing the object each second?
They are the same.
What are stationary objects?
Stationary object refers to an object that is not moving
When an object is moving in relation to a stationary object is the stationary object called the reference point?
true
When an object is seen moving in relation to a stationary object the stationary object is calle the?
The stationary object is known as a frame of reference. The earth is a common frame of reference for humans.
What is a sentence with ultrasonic in it?
When an object starts to move at ultrasonic speeds it will create a sonic boom.
What is meant by ultrasonic range finders?
An ultrasonic rangefinder sends out a short beep of sound, and measuresthe time it takes for an echo to come back. Knowing the speed of sound,it calculates the distance to the object the sound echoed off of.It uses sound at a frequency that your ears can't hear, so the beep is called "ultrasonic".
Force acting on stationary object?
The forces acting on a stationary object are:PushPullGravity
