Answer:
To catch a ball, the fielder has to stop the ball. This means, force is applied against the motion of the ball. So, between the fielder applies force on the ball and the ball comes to rest, the ball moves in the direction opposite to the direction of force. Thus work is negative.

How many moles are in 6.777 x 1023 atoms of CO2. Watch your significant figures. Question 2 options: 1 atoms CO2 1.125 moles CO2 1.13 moles 1.13 atoms CO2
Answers
Answer:
1.13moles
Explanation:
Given parameters:
Number of atoms = 6.777 x 10²³ atoms
Unknown:
Number of moles = ?
Solution:
A mole of a substance contains the avogadro's number of particles
6.02 x 10²³ particles = 1 mole
6.777 x 10²³ atoms will contain [tex]\frac{ 6.777 x 10^{23} }{6.02 x 10^{23} }[/tex] = 1.13moles

This is the type of wave that travels in one direction but the energy travels in the opposite direction
Answers
Answer:
Transverse wave
Explanation:
A wave is defined as a disturbance along a medium which transfers energy from one point to another.
A wave may be classified as transverse or longitudinal based on the direction of energy transfer relative to the direction of wave motion.
In a transverse wave, energy is transferred in a direction perpendicular to the direction of wave travel. Hence, the direction in which the energy travels is opposite to the direction in which the wave travels.

If 23.17 g of beryllium (Be) reacts with water at standard temperature and pressure,
how many liters of hydrogen (H2) are produced?
Answers
Volume of H2 produced = 57.6576 L
Further explanationGiven
23.17 g Be
Required
Volume of H2
Solution
Reaction
Be(s)+H2O(g)→BeO(s)+H2(g)
mol Be :
= 23.17 g : 9 g/mol
= 2.574
From the equation, mol H2 : mol Be = 1 : 1, so mol H2 = 2.574
Volume H2(assumed at STP, 1 mol=22.4 L) :
= 2.574 x 22.4 L
= 57.6576 L

Which of the following are held together by nonpolar covalent bonds? PLEASE HELP
Answers
Answer:
The atoms of chlorine are held together by non-polar covalent bonds. Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
C. Atoms of chlorine (CI)
A covalent bond is created when the electrons from the two involved atoms are shared equally.The pair of electrons involved in this kind of bonding is referred to as the shared pair or bonding pair. Here the atoms of chlorine have non-polar covalent bonds. The correct option is C.
What are non-polar covalent bonds?A non-polar covalent connection is created when atoms with an equal amount of electrons share one another. The electronegativity of the two atoms is equivalent. When two atoms with similar electron affinities join together, like in the case of diatomic elements, it happens.
Non-polar covalent compounds are those in which there is no variation in electronegativity. In these compounds, the electronegativity does not change, preventing the motion of the bond pair's electrons in the direction of the linked atoms.
As a result, a molecule is non-polar and non-conducting since there is no bond or dipole moment between its atoms and no buildup of charges on the atoms.
Thus the correct option is C.

Answer:
Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
