A wave with a frequency of 400 Hz is traveling at a speed of 100 m/s. What is the ​wavelength​? ​

shutvik [7]

The velocity (speed) of a sound wave (any wave in fact) is related to its frequency and wavelength by the equation . This is easy to remember since it's a distance divided by a time because frequency is the inverse of the period.

Since for sound traveling through the given solid object we have that  and , the speed of sound will be:

azamat

Answer:

<h2>They provide a 3’ end for the DNA polymerase.</h2>

Explanation:

Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.  

Polymerase chain reaction was invented by Kary Mullis in 1983.

Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.

Which type of respirator delivers clean air to the breathing zone from a tank worn by the operator?
MissTica

An air-purifying respirator that employs a blower to pump air through filters or cartridges and into the user's breathing zone is known as a powered air-purifying respirator, or PAPR. In comparison to a powered or negative-pressure half mask, this generates a positive pressure inside the facepiece or hood, increasing protection.

<h3>What kind of respirator offers a separate source of clean air?</h3>

For entry into or exit from settings regarded as IDLH, Self-Contained Breathing Apparatus (SCBAs) are employed. They can be either open circuit or closed circuit and contain their own breathing air supply.

<h3>What 2 categories of respirators exist?</h3>

Air-purifying and supplied-air respirators are the two main categories of respirators. Respirators that purify the air remove airborne pollutants such particles, dangerous vapors, and/or gases. They are suitable for use in surroundings with low levels of pollution and in areas with enough oxygen.

<h3>When should you use an air purifying respirator?</h3>

a small, unproven area. a lack of oxygen in the atmosphere. Firefighting. Contaminants with a lower explosive limit (LEL—the concentration at which a gas or vapour could ignite) of at least 20%
