Answer: Option (a) is the correct answer.
Explanation:
A formula that represents how atoms are linked or joined together is known as a structural formula.
For example, the model given in the image (in question) represents arrangement of all the atoms. Therefore, it is a structural formula.
Whereas a chemical formula represents a compound along with ratio of compounds.
A space filling model and a ball-stick model is a three dimensional model. In space filling model atoms are represented by spheres whereas in ball stick model atoms are represented by ball and bonds are represented by stick.
Answer:
Explanation:
Given that,
Initial speed, u = 0
Final speed, v = 40 m/s
Time, t = 2 s
We need to find the acceleration of the aircraft. We know that, acceleration is equal to the rate of change of velocity. So,
So, the acceleration of the aircraft is 
.
If they lose an electron, that means they become more positive since an electron is negatively charged. So the answer is ‘positive’
C light energy
The solar energy from the sun converts to chemical potential energy
The sentence is accurate, therefore TRUE is the answer.
