Answer:
The answer is X
Explanation:
Cause the highest points will most likely have the most potential energy
For lots of different reasons the can calculate the impact the car can have in certain types of crashes and create The safest ways to dissipate the crashes energy away from the driver and they can use air resistance to create a more fuel efficient and faster car
Those are only 2 example there are many more reasons though
In your question where as a particle is moving along side x-axis with a velocity of V(t) = sin2t. where as time T= pi/2 and has a position of x=3 so find the distance traveled by the particle. In my calculation i came up with an answer of -0.5 cos 2t+2.5
The standard reaction free energy is the total energy change of a chemical reaction that occurs at standard conditions. The standard reaction free energy is calculated by subtracting the heat of formation from the enthalpy of formation.
standard reaction free energy = -Hf-Hf
The standard Gibbs free energy, on the other hand, is the total of the enthalpy and the entropy. The Gibbs free energy is a thermodynamic potential that depends on the enthalpy and entropy of a system. The change in the Gibbs free energy is equal to ΔG=ΔH-TΔS.
The enthalpy of formation is a measure of how much heat must be put in to break down a compound into its constituent elements. The heat of formation is an estimate of how much heat will be released when the same compound is formed from its constituent elements.
<h3>How is the standard reaction free energy calculated?</h3>
The standard reaction free energy is the change in Gibbs free energy, which is the enthalpy minus the entropy. This can be calculated by using E=ΔH-TΔS. The ΔG for a reaction with a standard state change from atm to K (the most common atmospheric pressure and temperature), and 1 mol of reactants is equal to 0. The ΔG for a reaction with standard state changes from 1 atm to 298 K and from to atm are equal to .
The standard reaction free energy can be calculated by using the following equation:
E=ΔH-TΔS, where E is the standard free energy of the reaction.

<span>Of course.
Throw a ball into the air. Right after you release it, the velocity is upward, but the acceleration is downward.
Later, the velocity falls to zero; the acceleration is still downward.
Still later, the velocity goes downward; the acceleration is still downward.</span>
