Then we would not have oxygen because plants give oxygen in order to breathe
Yes- as long as the roller coaster car is not powered once it leaves the station and energy loss due to resistance can be ignored.
Energies of a system:
- Potential Energy
- Kinetic Energy
- The term "Mechanical Energy" refers to the sum of both types of energy.
A roller coaster car moving along a level track with an initial velocity has mechanical energy in the form of kinetic energy.
The car would slow down while gaining height as its kinetic energy converts to gravitational potential energy when moving upwards along the track. It would have no kinetic energy since all its mechanical energy are now in the form of gravitational potential energy in case it comes to a stop before reaching the top of the track.
Similarly, the car gains speed while losing height as some of its gravitational energy is converted to kinetic energy when it travels downwards.
The mechanical energy of this vehicle conserves since any of the movements, moving upslope, downslope, or level, would ensure that
<em>Loss in Potential Energy </em>=<em> Gain in Kinetic Energy</em>
and vice versa.
Answer:
Phlogopite is a member of mica group family of phyllosilicates mineral. Color is a yellow, greenish, or reddish-brown. It is the magnesium endmember of the biotite stable answer series, with the chemical formulation KMg3AlSi3O10 (F, OH) 2.
Explanation:
Answer:
It is important to separate mixture into pure or relatively pure substances when performing a chemical analysis SO AS TO KNOW THE PROPERTIES COMING FROM EACH PART MIXTURE WHICH MAY INTERFERE WITH THE SEPARATION.
Explanation:
In chemistry, Mixture is the combination of two or more substances which are not combine chemically.
Mixture contain different substances with different physical and chemical properties.
It is important to purify the substances in a mixture so as to identify what properties are coming from each mixture and also some part of the mixture can interfere with the properties of other mixture present for skewing analysis.
Answer: Blue
Explanation: Blue light has a smaller wavelength, therefore the increase in frequency.
