Hi there!
Recall Newton's Second Law:

∑F = Net force (N)
m = mass (kg)
a = acceleration (m/s²)
We are already given the mass and acceleration, so we can plug these values into the equation:
∑F = 1600 · 4.5 = 7200 N
Answer:
Hello! Your answer is, sound in the air is faster
Explanation:
The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they're totally different scales.
Hope I helped! Ask me anything if you have any questions! Brainiest plz. Hope you make an 100% and have a nice day! -Amelia♥
One point will be X1,Y1 and the other will be X2,Y2. It does not matter which is which except that X1 and Y1 have to be the same point and X2 and Y2 have to be the same point. For example, let's say you were given (2,3) and (6,8). No matter which point is X1,Y1 and the other is X2,Y2, the slope will still be 5/4.
The rise is the change in y from one point to the other. The run would be the change in x from one point to the other.
Answer:
1) Acids have a sour taste.
Acid formulas start with "H", contain hydrogen and some react with active metals in a single replacement reaction to give off hydrogen gas.
An acid will turn blue litmus paper red
All acids are SOLUBLE in water.
Acids have a pH below 7.
2) Bases are bitter to taste a bitter taste is characteristic of all bases.
trong bases are very corrosive and can burn the skin.
Bases may or may not be soluble in water Bases that can dissolve in water are called alkalis
They can conduct electricity.
Bases lose their basicity when mixed with acids.
