Answer:
they become ionized and change to ions
Answer: option "A" is correct
Explanation: the closet to understand the intensity level will be from 80db (decibels) upwards. So option a which is 84db is the answer. Thank you.
One-half second after starting from rest, a freely falling object will have a speed of about 5 m/s.
<h3>
What do you mean by falling object?</h3>
Falling things include goods, tools, garbage, and rubbish that are blown, dropped, or displaced from heights.
Physical science research frequently involves the study of gravity. Of course, what makes things fall is the force of gravity. A force of attraction between two objects is constant. This pulling force is similar to the pull of gravity.
given free fall from rest i.e.
initial velocity u=0 m/s
acceleration a = 10m/s2
time t=0.5 seconds
we know final velocity v = u + at = 0 + (10 *0.5) = 5m/s
