O Decrease the velocity of an object
O Decrease the mass of an object
O All of the Above
Engineers do to lower impact forces by increasing the collision duration.
What is meant by collision?Any time two objects collide, a collision occurs. Conservation of momentum and conservation of energy are typically used to resolve collision-related problems.
Collisions can occur in two ways:
Momentum is conserved during inelastic collisions, while momentum and kinetic energy are both preserved during elastic collisions.Completely inelastic collisions, in which the impacted objects stick together, are the simplest to analyze. The conservation of momentum allows us to determine that the two objects have the same final velocity.In elastic collisions, no energy is wasted to other forms and is entirely retained as kinetic energy. It follows that momentum and kinetic energy are both preserved.

1. 86 g h2 is allowed to react with 9. 70 g n2, producing 1. 24 g nh3. Part a what is the theoretical yield in grams for this reaction under the given conditions?.
1.86 g H₂ is allowed to react with 9.70 g N₂ producing 1.24 g NH₃. the theoretical yield in grams for this reaction under given conditions is 10.54 g.
The balanced chemical equation is given by :
N₂ + 3H₂ ------> 2NH₃
it is clear from the reaction that :
1 mole of N₂ react with 3 moles of H₂ to produced 2 mole of NH₃.
the molar mass of compounds are :
H₂ = 2 g/mol
N₂ = 28 g/mol
NH₃ = 17 g/mol
3moles of H₂ × 1 g/mol= 6 g
1 mole of N₂ × 28 g/mol= 28 g
2 moles of 2NH₃ × 17 g/mol = 34 g
now we have to find out the limiting reagent :
28 g of N₂ react with 6 g of H₂ , 9.70 N₂ will react with how much mass of H₂
mass of H₂ = (9.70 g of N₂ × 6 g of H₂) / 28 g of N₂
= 2.07 g
but 2.07 g H₂ is not available , only 1.86 g are available .so, H₂ is a limiting reagent.
The theoretical yield in the given case:
mass of NH₃ = (1.86 g of H₂ × 34 g of NH₃ ) / 6 g of H₂
= 10.54 g
Thus, 1.86 g H₂ is allowed to react with 9.70 g N₂ producing 1.24 g NH₃. the theoretical yield in grams for this reaction under given conditions is 10.54 g.

In practical terms, this principle implies that if the forward reaction of a system in equilibrium is endothermic and the backward reaction is exothermic, adding more heat to the system will shift the equilibrium position of the reaction to favor the forward reaction.
Considering the given chemical equilibrium, the forward reaction is endothermic and results in the formation of OH⁻ ions.

Sally is swimming 6 meters every 2 seconds. this increase in speed took 10 seconds. what is the acceleration during this second part of the race?
The acceleration for the second part of the race is 0.3m/s².
How to calculate acceleration?Acceleration is the amount by which a speed or velocity increases. The acceleration can be calculated by dividing the speed of the object by the time taken as follows:
Acceleration = speed/time
According to this question, Sally is swimming 6 meters every 2 seconds, however, this increase in speed took 10 seconds.
The speed Sally is swimming is 3m/s i.e. 6/2. Hence, the acceleration can be calculated as follows:

A student is 159cm tall and weighs45.8kg what is the height in inches and weight in pounds ?
Height in inches is 62.6 inches and weight in pounds are 101 pounds
Height is a way to measure someone or something from base to top or head to toe
Here given data is student height = 159cm tall and weight is = 45.8kg
So we have to convert
Height in cm = height in inches
Weight in kg = weight in pounds
So, 1 inches = 2.45cm
Height = 159cm×1 inches/ 2.45cm
Height = 62.6inches
Now, 1kg = 2.2045 pounds
Weight = 45.8kg×2.2045 pounds/1kg
Weight = 101 pounds or lbs

The experiment determines calorimetry of the peanut and the chip, using water to capture the energy of the samples when they were burned. A 10 g sample of each type of food was burned underneath a metal can that held 50 g of water. A thermometer captured how much the temperature of the water increased. The water increased by 7 degrees for the peanut and 3 degrees for the chip. What conclusion can be drawn?
The chip has more energy than the peanut.
The peanut has more energy than the chip.
The experiment was flawed because more than one variable was being tested.
The peanut and the chip have the same amount of energy.
Since the water increased by 7 degrees for the peanut and 3 degrees for the chip, the conclusion would be that the peanut has more energy than the chip.
CalorimetryCalorimetry is the science of measuring the quantity of energy, usually in the form of heat, that is released during a reaction.
In this case, the energy released by the peanut and the chip were measured using calorimetry. The energy released was captured by the water and helps raise the temperature of the water.
The more energy released by the substances, the more the temperature of the water is raised.
Thus, since the peanut raised the temperature of the water by 7 degrees while the chip was only able to raise it by just 3 degrees, one can effectively conclude that the peanut has more energy than the chip.

while starting a car, a lead acid battery converts 0.63 grams of pb (207.2 g/mol) at the anode into pbso4. if a current of 0.140 a is used to recharge the battery, how long will recharge take?
Based on the number of electrons required and the strength of the electric current, we can calculate that the time needed to recharge the battery will be 1 hour, 9 minutes, and 23 seconds.
First, we calculate the number of moles of lead oxidized to lead(II) sulfate.
n = m/M = 0.63 g / 207.2 g/mol = 0.00304 mol
Then, we calculate the number of electrons needed to reduce this amount of lead(II) back into the elemental lead (each lead(II) ion requires two electrons):
[tex]N = 2 electrons * 0.00304 mol * 6.02 *10^{23} mol^{-1} = 36.6 * 10^{20} electrons[/tex]
Now that we know the number of electrons required, we can divide that amount by the strength of the electric current used to calculate the time required to recharge the battery:
[tex]t = N / I = 36.6*10^{20} electrons / 0.140 A = 36.6*10^{20} electrons / 0.140 * (6.28*10^{18} electrons/s) = 4163 s[/tex]
Because 1 hour has 3600 seconds, and a minute has 60 s, the time required will be 1 hour, 9 minutes, and 23 seconds.

Mass of magnesium ribbon is 0.21 g.
Mass of oxygen gas reacts with magnesium is 0.11 g
Number of moles of magnesium is 0.00875
Number of moles of oxygen is 0.0068.
Ratio of moles of magnesium and oxygen = 1.2 : 1
The number of moles of a substance equals the ratio of its given mass in a chemical reaction to the mass of one mole of that substance. One mole of any substance equals Avogadro's number, that is, 6.023 × 10²³.
we know that mass of crucible and lid = 35.56 g
mass of crucible and lid and magnesium = 35.77 g
Thus mass of magnesium = 35.77 - 35.56 = 0.21 g
mass of crucible and lid and magnesium oxide = 35.88 g
thus, mass of oxygen = 35.88 - 35.77 = 0.11 g
Now, Number of moles of magnesium = 0.21/24 = 0.00875
Number of moles of Oxygen = 0.11/16 = 0.0068
Ratio of Number of moles of magnesium to Number of moles of Oxygen = 0.00875/0.0068 = 1.2 : 1.

sodium hydroxide solution in a titration
H2SO4 + 2NaOH → Na2SO4 + 2H2O
The concentration of sulfuric acid in mol/dm3 and g/dm3 would be 5.194 and 0.053 respectively.
Stoichiometric problemFrom the equation of the reaction, the mole ratio of the concentrated sulfuric acid and sodium hydroxide solution is 1:2.
Recall that: mole = molarity x volume
For 26.5 cm3 0.100 mol/dm3 sodium hydroxide solution, the number of moles of the solute in the solution can be calculated as:
26.5/1000 x 0.100 = 0.00265 moles
The equivalent number of moles of the concentrated sulfuric acid will be:
0.00265/2 = 0.001325 moles
Also, recall that:
Concentration in g/dm3 = mass/volume
concentration in mol/dm3 = mole/volume
For 0.001325, 25.0 cm3 sulfuric acid:
mass = 0.001325 x 98 = 0.12985 g
Concentration in g/dm3 = 0.012985/0.025
= 5.194 g/dm3
Concentration in mole/dm3 = 0.001325/0.025
= 0.053 mol/dm3
