Bats use ultrasound in echolocation. This sound is characterized by __low frequencylow amplitudehigh frequencyhigh amplitude

Answers

Answer 1

Answer: Bats use high frequency. Whenever somebody says a quantity is "high",
you have to ask "compared to what ?". In this case, it's compared to human
hearing ... we can't hear bats at all, or if we can, it just sounds like a 'click'.

Answer 2

Answer:

Answer:

Both use reflected sound waves.

Wave X has an amplitude of 5 and wave Y has an amplitude of 4. What will happen when the crest of wave X meets the crest of wave Y?A crest with an amplitude of 1 will form.
A trough with an amplitude of 1 will form.
A crest with an amplitude of 9 will form.
A trough with an amplitude of 9 will form.

Answers

Answer: A crest with an amplitude of 9 will form.

Explanation:

From super position principle, we know that when two waves move in same medium meet, then the net amplitude of the super imposed waves is sum of amplitudes of individual waves.

A constructive superposition takes place when crest meets crest and crest is formed of higher amplitude or trough meets trough and forms trough of higher amplitude. A destructive superposition takes place when crest of one meets trough of other -a crest or trough can form depending on the larger amplitude of either.

In the given situation, crest of wave X meets crest of wave Y. The amplitude of the super imposed wave would be = 5 + 4 = 9 and a crest would form.

The right answer for the question that is being asked and shown above is that: "A crest with an amplitude of 9 will form." Wave X has an amplitude of 5 and wave Y has an amplitude of 4. the crest of wave X meets the crest of wave Y is that A crest with an amplitude of 9 will form.

Radiation transfers energy by moving matter. Please select the best answer from the choices provideda. True
b. False

Answers

The answer is b. False because radiation transfers energy by the propagation of waves within the electromagnetic spectrum and the travel of photons. Therefore, no matter is moved within this process.

False

A physical science test book has a mass of 2.2 kg what is the weight on mars??? please help

Answers

Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Test Book's weight on mars = 8.1 N.

What is different between mass and weight?

The distinction between Mass and Weight is Weight is a measure of force, while mass is a measure of inertia. Many people use these two terms interchangeably.
The mass of a body is the amount of matter contained within it, whereas the weight of a body is the force acting on it as a result of gravity's acceleration. In chemistry, this is the primary distinction between mass and weight.
Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Weight = (mass) x (gravity)

= (2.2 kg) x (3.7 m/s^2)

= 8.1 newtons
