Calorimetry :
<em><u>the process of measuring the amount of heat released or absorbed during a chemical reaction</u></em>.
Calorimeter :
<em><u>device for measuring the heat developed during a mechanical, electrical, or chemical reaction, and for calculating the heat capacity of materials</u></em>.
Answer:
Frequency, f = 0.2 Hz
Explanation:
We have,
A baseball player throws 4 balls every 20 seconds.
It is required to find the frequency of the baseball.
Frequency of an object is defined as the number of times an event occurs. It is given by number of throws per unit time. It can be given by :
So, the frequency of his throw is 0.2 Hz.
The earth rotates (spins) at the same time as it orbits in a circular motion around the sun. fun fact : it takes 365 days to complete 1 orbit for 3 years and then 366 days for a leap year! you don't have to put that last part but maybe for some extra points you can!
You should use math on your mind and you should balance the bottle
The electrostatic force between the two charges is
Explanation:
The electrostatic force between two charges is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, we have the following data:
is the magnitude of the two charges, where
is the fundamental charge
is the separation between the two charges
Substutiting into the equation, we find the force:
