The answer is: a relatively large electron cloud.
Atom is composed of the nucleus and the electron cloud.
Protons (positive particles) and neutrons (neutral particles) are in the nucleus of an atom and electrons (negative particles) are in the electron cloud.
Nucleus is in the centar of the atom atom and electron cloud is surrounding it.
Atoms have their mass concentrated in a very small nucleus.
Answer:
The speed of a spound wave in this water is 1484.1 m/s
Explanation:
Step 1: Data given
Frequency = 349.2 Hz
Wavelength = 4.25 m
Step 2: Calculate the speed
v = f*λ
⇒ with v= the speed of a sound wave in this water
⇒ with f = the frequency = 349.2 Hz
⇒ with λ = the wavelength = 4.25 m
v = 349.2 Hz * 4.25 m = 1484.1 m/s
The speed of a spound wave in this water is 1484.1 m/s
1 Cal ---------- 4.184 J
? Cal ---------- 130.0 J
130.0 x 1 / 4.184 => 31.07 Cal
hope this helps!
Answer: Molarity of the prepared solution is 
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
where,
n= moles of solute
= volume of solution in ml = 500 ml
moles of solute =
Now put all the given values in the formula of molarity, we get
Thus molarity of the prepared solution is
