The decibel level of a normal conversation, which has an intensity of watts/m2, is dB. If the decibel level goes up to 80, the intensity of the sound will be watts/m2. Use the formula , where is the sound level in decibels, I is the intensity of sound you are measuring, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

step-by-step explanation:

3024 rhe base is what up in worry about

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
