The amplitude of a wave is it's _________ or energy
Please help me :D I’m begging rn lol
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.

Graphite has a specific heat of 0.709 J/gºC. If a 25 gram piece of graphite is cooled
by 17°C, how much energy was lost by the graphite?
Answer:
[tex]\boxed {\boxed {\sf 301.325 \ Joules }}[/tex]
Explanation:
Since we are given the mass, specific heat, and change in temperature, we should use this formula for energy:
[tex]q=mc \Delta T[/tex]
The mass of the graphite is 25 grams. Graphite's specific heat is 0.709 J/g °C. The change in temperature is 17 degrees Celsius.
[tex]m= 25 \ g \\c= 0.709 \ J/g \ \textdegree C \\\Delta T= 17 \ \textdegree C[/tex]
Substitute the values into the formula.
[tex]q= (25 \ g)( 0.709 \ J/g \ \textdegree C )( 17 \ \textdegree C)[/tex]
Multiply the first two numbers. The grams will cancel.
[tex]q= 17.725 \ J/ \textdegree C(17 \ \textdegree C)[/tex]
Multiply again. This time the degrees Celsius cancel.
[tex]q= 301.325 \ J[/tex]
The graphite loses 301.325 Joules of energy.

Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?
Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
Reaction stoichiometryIn first place, the balanced reaction is:
4 NH₃ + 3 O₂ → 2 N₂+ 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 molesThe molar mass of the compounds is:
NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 gramsMass of N₂ formedThe following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?
[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]
mass of N₂= 56.42 grams
Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
