Answer:
The correct answer is: A. salt
Explanation:
The salt corresponds to sodium chloride, whose chemical formula is NaCl. A compound is defined as that substance formed by a combination of 2 or more atoms.
If you drop an object, it accelerates downward at 9.8 m/s2 (in the absence of air resistance). If instead, you throw it downward, its downward acceleration after release is 9.8 m/s2.
Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities and accelerations. The direction of the net force acting on an object determines the direction of its acceleration. Uniform acceleration, non-uniform acceleration, and average acceleration are the three different forms of accelerated motions.
A free-falling object experiences a downward acceleration of 9.8 m/s/s (on Earth). This specific designation is given to the numerical value for an object in free fall because it is such an essential value. The longer an object is in free fall, the faster it descends toward the ground due to gravity. In actuality, an object's velocity rises by 9.8 m/s2, so it reaches 9.8 m/s by the time it begins to fall.

Whenever these are an alarming due to a foreign antigen, the Helper T cells, Memory T cells, and Cytotoxic T cells are being produced. Helper T cells to recognize the specific foreign antigen that is entering the body, Memory T cells to remember the specific foreign antigen that is attacking, and Cytotoxic T cells that are for the destruction of the foreign cells and produce cytokines to attract macrophages
Answer:
PART A)
L = 97.4 dB
PART B)
PART C)
L = 67.9 dB
Explanation:
PART A)
level of sound is given as
now we have
PART B)
Since source is a spherical source
so here the intensity of sound is inversely depends on the square of the distance from the source
PART C)
level of sound is given as
now we have
