What else can I help you with?
What you compare something to in order to determine if an object is moving or stationary?
You can compare the object's position relative to a reference point or a fixed landmark to determine if it is moving or stationary. If the object is changing its position relative to the reference point over time, then it is moving. If its position remains constant with respect to the reference point, then it is stationary.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary abserver?
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler effect. As the object moves towards the observer, the observer perceives a higher frequency (higher pitch) than what is actually emitted. Conversely, as the object moves away from the observer, the perceived frequency is lower than the actual frequency emitted.
What is ultrasonic sensor used for?
Ultrasonic sensors are commonly used to measure distance by sending out sound waves and detecting when they bounce back. They are frequently used in robotics for obstacle avoidance, level sensing, and distance measurement applications.
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 is speed of a stationary object?
In the frame of reference in which the object is stationary, its speed is zero. (Actually, that's kind of a definition of "stationary".)

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?
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 is a sentence with ultrasonic in it?
When an object starts to move at ultrasonic speeds it will create a sonic boom.
When an object is moving in relation to a stationary object is the stationary object called the reference point?
true
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".
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.
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 is speed of a stationary object?
In the frame of reference in which the object is stationary, its speed is zero. (Actually, that's kind of a definition of "stationary".)
