Answer:
The solution is given below.
Explanation:
Speed = Distance(m)/Time(sec.)
Distance traveled = 150 m
Time taken = 3.5 seconds
Speed of car = 150/3.5 = 42.86 m/s
So the car traveled at a speed of 42.86 m/s.
Answer:
330,000
Explanation:
Since there are only 2 significant figures in 0.024 ( and 0.024 is the number with the least number of significant numbers), the answer is 330,000, not 331,000.
C - Identify the element because each element has it’s own spectra light , which are released when electrons return to ground state
Answer:
here you go. I took the test :)
Explanation:
Bromine has larger ionic radius and atomic radius than fluorine.
Fluorine has larger ionisation energy and electronegativity than bromine.
<h3>What are halogen?</h3>
Halogen are those elements that are found in group 7 of the periodic table.
Fluorine is in period two of the periodic table, meaning that it contains electrons in only the first two energy levels at ground state. It has a higher ionization energy and electronegativity than bromine.
