a kid on a playground swing makes 6 complete to-and-from swings each 30 seconds (a) the frequency of the swinging is? (b) the pe
Mariana [72]

The frequency is how many per second:

       (6 swings)/(30 sec) = (6/30) swing/sec = 0.2 per sec = 0.2 Hz .

The period is how long each one takes, or seconds per swing.
It's exactly the flip of frequency.
So we could just take the frequency, flip it, and find   1 / 0.2 ,
but let's do it the long way:

      (30 sec) / (6 swings) = (30/6) sec/swing =  5 seconds  .

What is the internal energy of 4.50 mol of N2 gas at 253°C? To solve this
Finger [1]

The internal energy of the gas is 49,200 J

Explanation:

The internal energy of a diatomic gas, such as N_2, is given by

U=\frac{5}{2}nRT

where

n is the number of moles

R is the gas constant

T is the absolute temperature of the gas

For the gas in this problem, we have:

n = 4.50 (number of moles)

R = 8.31 J/(mol·K) (gas constant)

T=253^{\circ} + 273 = 526 K (absolute temperature)

Substituting, we find:

U=\frac{5}{2}(4.50)(8.31)(526)=49,200 J

A basketball star exerts a force of 3225 n (average value) upon the gym floor in order to accelerate his 76.5-kg body upward. de
ryzh [129]
F = m . g  = 76.5 x 9..8 = 749.7
Net Force = 3225 - 749.7 = 2475.3

F = m.a
2475.3 = 76.5 a

a  = 32.35



V = at + v1
V = at + 0
V = 32.35 x 0.15
V = 4.8525

Water is a compound because it is what?Water is a compound because it
seraphim [82]

Water is a compound because it always has two hydrogen atoms for each oxygen atom. Water can be broken down into simpler substances. Water is a compound because pure water is composed of only H₂O molecules. Each molecule of water is a chemical combination of two hydrogen atoms and one oxygen atom.  Water is a type of molecular compound.

\boxed{~The~Answer~is~B.~}

<h3>Further explanation</h3>
  • Compounds are substances composed of two or more different elements chemically combined that can be separated into simpler substances only by chemical reactions.
  • Water, for example, is a compound because pure water is composed of only H₂O molecules. Each molecule of water is a chemical combination of two hydrogen atoms and one oxygen atom.
  • A molecular bond or covalent bond occurs as a result of electrons can be shared between atoms. Molecular compounds have molecular (covalent) bonds.
  • An ionic bond occurs as a result of electrons can be completely removed from one atom and given to another. Ionic compounds have ionic bonds.
  • Examples of other molecular compounds are carbon dioxide (CO₂) and glucose (C₆H₁₂O₆). Each molecule of CO₂ is a chemical combination of two oxygen atoms and one carbon atom. Each molecule of C₆H₁₂O₆ is a chemical combination of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms.
  • Table salt (NaCl) is a compound because it is made from more than one kind of element (Na and Cl), but it is not a molecule because the bond that holds NaCl together is an ionic bond. An electron from the outer shell of sodium is released and taken by chlorine to reach octet conditions on both sides, that is how ionic bonds occur. Thus NaCl is an ionic compound.
  • A diatomic molecule is a molecule made from two atoms of the same type. For example, oxygen gas in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element, i.e. oxygen. Another example is hydrogen gas, nitrogen gas, and chlorine gas.
  • Elements are the simplest forms of matter and therefore cannot be broken down into simpler substances by any chemical or physical reactions. Some examples of elements include hydrogen, oxygen, carbon, sodium, iron, and sulfur. Elements can combine with other elements to synthesize compounds.
