Answer:
Heat of reaction or enthalpy of reaction (ΔH)
Explanation:
The heat of reaction or enthalpy of reaction (ΔH) is the amount of heat energy that the system must release or absorb so that the temperature remains constant throughout the chemical reaction process. In other words, the heat of reaction or enthalpy of reaction (ΔH) is the change in the enthalpy of a chemical reaction (the energy absorbed or released into it) that occurs at a constant pressure.
Then, this energy can be observed in the following way:
Every substance has a quantity of energy stored in its links. When the energy contained in the reagents is greater than that contained in the products, the reaction is exothermic because energy release occurs. When the energy contained in the reagents is less than that contained in the products, an endothermic reaction occurs because energy absorption occurs.
That energy contained in the substances is called enthalpy (H).
Then the enthalpy can be defined as the difference between the sum of the enthalpies of the products and the sum of the enthalpies of the reactants.
Answer:
In order to prevent the aliased frequency from we need to sample at with a sampling frequency that is minimum 2 times the highest frequency where information exit i.e 2 × 750 = 1500 Hz
Explanation:
The explanation is shown on the first and second uploaded image
Explanation:
It is given that,
The distance from the pitcher's mound to the batter is 43 feet, d = 43 feet = 0.00814 miles
Speed with which ball leaves the ball, v = 110 mph
Let t is the time elapses between the hit and the ball reaching the pitcher. It is given by :
t = 0.000074 hours
or
t = 0.2664 seconds
So, the time between the hit and the ball reaching the pitcher is 0.2664 seconds. Hence, this is the required solution.
A scientific law is absolute, it cannot be proven wrong. A scientific theory is like a belief, it has been proven but can also be argued or disproven.
