Answer:
13.1 m/s
Explanation:
If we assume that there is not air resistance then the horizontal component of velocity remains constant. That is 1.23 m/s
The vertical component of final velocity can be calculated the following way:
So the final velocity will be the square root of the sum of the squares of the component
v² = 1.23² + 13.0²
v = 13.1 m/s
Problem the mount I cough my so the newer I 75.4
Answer:
The salt is dissolved by the water and heat. If the pot isn't boiling, the salt wouldn't dissolve, it would stay undissolved.
Answer: CaF2
Explanation:
Calcium is a metal and has 2+ cation charge. While F us in group 7 with an oxidation of -1.
So. Ca²+ F- do the criss cross rule where the charge of the cation will be the subscript of the anion and vice versa. So the result is CaF2
The correct answer would be C. Unaware because it is the opposite of leery
