Answer:
a. Relative humidity increases: a decrease in temperature without a change in the amount of water vapor in the atmosphere.
Explanation:
Colder air requires less humidity to saturate compared to warmer air. Therefore, the relative humidity depends on the air temperature. If the temperature drops and the water vapor content remains the same, relative humidity increases. If the temperature increases and the water vapor content remains the same, relative humidity decreases. Additionally, a greater amount of water vapor in the air increases the relative humudity.
Answer:
2H₂S + SO₂ —> 2H₂O + 3S
Explanation:
From the question given above, the following equation were obtained:
H₂S + SO₂ —> H₂O + S
The equation can be balance as illustrated below:
H₂S + SO₂ —> H₂O + S
There are 2 atoms of O on the left side and 1 atom on the right side it can be balance by writing 2 before H₂O as shown below:
H₂S + SO₂ —> 2H₂O + S
There are 2 atoms of H on the left side and 4 atoms on the right side. It can be balance by writing 2 before H₂S as shown below:
2H₂S + SO₂ —> 2H₂O + S
There are 3 atoms of S on the left side and 1 atom on the right side. It can be balance by writing 3 before S as shown below:
2H₂S + SO₂ —> 2H₂O + 3S
Now, the equation is balanced.!
Answer: 
Explanation:
We know that the formula for acceleration is given by:
, where v = Final velocity
u= Initial velocity
Given : The driver of a car traveling 110 km/h slams on the brakes so that the car undergoes a constant acceleration.
i.e. u= 110 km/h 
[∵ 1 km= 100 meters and 1 hour = 3600 seconds]
v= 0 m/s ( At brake , final velocity becomes 0)
t=4.5 seconds
Substitute all the values in the formula , we get
Hence, the average acceleration of the car during braking is .
It's commonly referred to as an electric current.
I think it is 3 but I know it may be wrong.
