Answer:
Substances used to make the bomb
The area it was placed
Which people were in that area
How the bomb was set off
Explanation:
Examining the residues left at the scene by the bomb could tell forensics what the bomb was made out of, and the police could investigate possible leads about people who purchased (or have access to) such materials.
The area should give clues because security cameras could be used to trace who was there that should not be. There would be a possible suspect.
If it is a public place, then we can see if there is anyone of importance (to the suspect) that was there at that time.
If a remote detonator was used to set off the bomb, then the suspect would have to be relatively close to the bomb.
Because the ones farther from the sun can't maintain a terrestrial life
The formula for acceleration if rearranged based on the force equation is- force over mass. So 5000/1200=4.16
Your answer is 4 m/s squared.
Answer:
Option B. Both have a pH less than 7, but H3PO4 has a lower pH than HCl
Explanation:
Those are acid, so the pH would be < 7.
H₃PO₄ is a weak acid with 3 dissociations
HCl is a strong acid.
pH depends on [H]⁺
H₃PO₄ → 3H⁺ + PO₄⁻³
HCl → H⁺ + Cl⁻
If both acid, have the same concentration, [H⁺]H₃PO₄ > [H⁺]HCl, that's why the pH from the phosphoric will be lower.
