Formic acid- Explanation The acid produced by ants is called formic acid. The name comes from the Latin word for ant, which is “Formica.” Chemically, it is a simple carboxylic acid. The most common species of black ant in the United States is the black carpenter ant, which delivers a small amount of formic acid through its jaws as it bites.
The reflected ray is rotated through 12°.
<h3 /><h3>What is reflection?</h3>
Freflection can be defined as the turning back of a ray of light when its strikes a plane's surface.
There are 2 laws of reflection
<h3>Laws of reflection</h3>
(1) The first law of reflection states that the incident ray the reflected ray and the normal all at the point of incidence lie in the same plane
(2) The second law of reflection states that the angle of incident is equal to the angle of reflection.
From the question, if the incidence ray is rotated through 6°, then the reflected ray is rotated through 12°
Hence, The reflected ray is rotated through 12°.
Answer:
electrical 'pressure' measurement
Explanation:
Answer:
Explanation:
Given:
Length of the string, L = 1 m
Mass per unit length, (m/L) = 2.0 × 10⁻³ kg/m
Tension in the string, T = 80N
Now, We know that,
Frequency, ................(1)
where, V = velocity
also,
substituting the values in the equation we get
Now using the equation (1)
also,
Hence, the required frequencies are
