Answer:
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
Explanation:
Answer:
D
Explanation:i think but dont get mad if im wrong
The initial velocity of Ms. Stafford is

, while her acceleration is

This is a uniform accelerated motion, so we can calculate the total distance travelled by Ms. Stafford in a time of

using the law of motion for a uniform accelerated motion:
Multiply these numbers and there’s your answer
Answer:
A. the speed of a reaction
Explanation:
The thermodynamic aspect of a reaction will show you the energy needed for a reaction to occur. If the energy difference(ΔG) is positive, which means the reaction is absorbing energy and it called endothermically. The opposite will be an exothermic reaction that will release energy, which means it doesn't need energy and the energy difference (ΔG) will be negative.
Thermodynamic can be used to determine a few things of a reaction, like the direction of the reaction, the extent, or temperature in which the reaction is spontaneous. But thermodynamic not used to find the speed of a reaction.
