Answer:
The electron from the ground state to occupy a next energy level. In this case,we say that the electron is excited
Answer: The given compound is 1-butene.
Explanation:
In simple hydrocarbons, if there are only single bonds present then the suffix "ane" is added to the name of hydrocarbon.
If there is a double bond then suffix "ene" is added to the name.
If there is a triple bond then suffix "yne" is added to the name.
For example, 
has one double bond which is at position 1 and there are four carbon atoms present.
Hence, name of this compound is 1-butene.

<u>Given:</u>
Force acting on the car moving it to the right = F1= 300 N
Force due to friction and air resistance moving it to the left = F2 = 150 N
<u>To determine:</u>
The net force on the car
<u>Explanation:</u>
Force is a vector. The force of friction acts in a direction opposite to the applied force.
If, F1 = 300N, right, then F2 = -150 N, left
Therefore, the net force acting on the car will be:
F = F1+F2 = 300 - 150 = 150 N
<u>Ans</u>: Since the force acting on the right is greater, the car will experience a net force of 150 N which will accelerate it to the right
