Answer:
False.
Explanation:
I am almost entirely sure that DNA testing had not been discovered at this time, but regardless of whether that is true, the very first criminal case that DNA testing was used in occurred in 1985. So no, it was not used commonly in the 20's.
Answer:
vapourization
Explanation:
When the water is heated, it changes into water vapour which is called vapourization or sometimes we can also call it evaporation.
Initia Velocity(u) :- 15m/s
Acceleration(a) :- 4m/s2
Time Taken(t) :- 50 Seconds
{ok a formula is there —->>> s = ut + 1/2 at2(it is ‘t’ square)….. now we will write like this and yeah don’t write this}
We Know,
s = ut + 1/2 at2
s = (15*50 + 1/2 *4*50*50)m
s= (750 + 5000)m
s = 5750 m
Therefore distance traveled is 5750 meters.
Hopefully this helps
