Yes, it is possible to determine the final speed of the rollercoaster if the initial speed and the height to be reached are known.
According the principle of conservation of energy, the total kinetic energy is equal to the total potential energy.
where;
- <em> is the </em><em>initial velocity</em><em> of the roller coaster</em>
- <em /><em> is the </em><em>final velocity </em><em>of the roller coaster</em>
- <em /><em> is </em><em>maximum height </em><em>reached by the roller coaster</em>
Thus, it is possible to determine the final speed of the rollercoaster if the initial speed and the height to be reached are known.

The physical changes are you are breaking down the food u eat and the chemical changes are when the enzymes in your stomach break down the food that you have already eaten
In a string of length L, the wavelength of the n-th harmonic of the standing wave produced in the string is given by:
The length of the string in this problem is L=3.5 m, therefore the wavelength of the 1st harmonic of the standing wave is:
The wavelength of the 2nd harmonic is:
The wavelength of the 4th harmonic is:
It is not possible to find any integer n such that , therefore the correct options are A, B and D.
2 meters per second for 8 seconds
1.5 meters per second for 8 seconds
The average speed should be 1.8 or 1.7 but I think its 1.8
First of all we know about the ionic bond that the attraction b/w two atoms the atom which lose electrons is become cation and have positive sing which one get electrons it become ionic. so in such sitivation the sodium lose one electons "that's why sodium has 1+ charge in Nacl chemacal bond."
hope it will help you and please get my answer in brainlist
"i should be thankfull of you"
