Answer:
constant acceleration
Explanation:
I may be wrong, but I'm almost positive cuz I am also taking physics. ;)
A rock is dropped from a 200 m high cliff. How long does it take to fall (a) the first 100 m and (b) the last 50 m?
The basic equation you want is:
s=at22
Solving for t:
t=2sa−−−√
We’ll assume a=9.8 , so 2a−−√=14.9−−−√≈0.4518
So, for (a)s=100 , so t=0.4518100−−−√=4.518
The total time is 0.4518200−−−√≈6.389
The time to fall 150 m is 0.4518150−−−√≈5.533
So the time to fall the last 50 m is 6.389 - 5.533 = 0.856 seconds

Answer:
Noise making has led to loss on hearing.
Explanation:
Supposing you like engaging in parties because of the noise of the sound system it can cause loss on hearing if continued for long
Answer:
E = 5291.00 N/C
Explanation:
Expression for capacitance is
where
A is area of square plate
D = DISTANCE BETWEEN THE PLATE
We know that capacitrnce and charge is related as
v = 9.523 V
Electric field is given as
=
E = 5291.00 V/m
E = 5291.00 N/C
