The rate of flow of Water flows through a pipe will be 30 cups per second.
What is the rate of flow?The distance covered by the particle or the body in an hour is called the rate of flow. It is a scalar quantity. It is the ratio of gallons to time.
We know that the speed formula
Rate of flow = Gallons/Time
Water flows through a pipe at a rate of 620 gallons every 5 1/2 minutes expressed at this rate of flow and cups per second.
We know that in one gallon, there are 16 cups.
5.5 minutes = 330 seconds
The rate of flow will be
Rate of flow = (620 x 16) / 330
Rate of flow = 30 cups per second
The rate of flow of Water flows through a pipe will be 30 cups per second.

Explanation:
Is the average atomic mass of a sample containing three lithium-6 and two lithium-7 closer to the mass of Li-6 or Li-7 ?
The average atomic mass of a sample closer to the mass of Li-6
Further explanationIsotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
Mass atom X = mass isotope 1 . % + mass isotope 2.%
three Li-6, mass number = 6
two Li-7, mass number = 7
total abundance = 5
abundance for Li-6 =
[tex]\tt \dfrac{3}{5}\times 100\5=60\%[/tex]
abundance for Li-7 =
[tex]\tt \dfrac{2}{5}\times 100\5=40\%[/tex]
Average atomic mass :
[tex]\tt (0.6\times 6)+(0.4\times 7)=6.4[/tex]

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?
Answer:
NaOH(aq)
Explanation:
NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)
Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.

Answer:
I searched the answer up on Brainly so its not my credit.
Explanation:
The answers D.
"If you have learned that metal + nonmetal ⟶ ionic bond, the answer is D, because N and C are the only pair of nonmetals.
However, if you have learned that a bond is ionic if the electronegativity difference (ΔEN) between the two atoms is greater than 0.7, the answer is A, B, and D.
The Li-Cl bond is definitely ionic.
For Na and C, ΔEN =1.62, so the Na-C bond is a highly polar covalent bond.
For Mg and C, ΔEN = 1.24, so the Mg-C bond is a polar covalent."

Earth contains a spinning electric filed. The spinning of earth core creates its magnetic field. Thus, option D is correct.
What is a spinning body?A body which rotates in its own axis is called a spinning body. Earth rotates about its along with revolving around sun. The outer core of earth generates electric current. This is called telluric current.
Flow of this current creates an electric current which is parallels to the surface of earth. The direction of magnetic field lines will be perpendicular to the direction of current. But it comes stronger when parallel to current.
A rotating electric current results in the generation of a magnetic field. Thus spinning of earth core generates a magnetic field and therefore, option D is correct.

A transformer has 150 turns in its primary coil and 50 turns in its secondary coil. If the input voltage is 12 V, what is the output voltage?
Answer:
36V
Explanation:
Given parameters:
Number of turns in primary coil = 150turns
Secondary coil turn = 50turns.
Input voltage = 12V
Unknown:
Output voltage = ?
Solution:
For this transformer problem, we use the expression;
[tex]\frac{N_{s} }{N_{p} }[/tex] = [tex]\frac{V_{s} }{V_{p} }[/tex]
Insert the parameters and solve;
Ns is the number of secondary turns
Np is the number of primary turns
Vs is the secondary voltage
Vp is the secondary voltage
Insert the parameters and solve;
[tex]\frac{150}{50}[/tex] = Output voltage / 12
Output voltage = 12 x 3 = 36V
