Electricity. I took something like this hope this helps :)
H atoms=4
S=2
O=8
Bcz it H2SO4 is multiplied with 2 therefore no. Of atoms will be multiplied by 2

Explanation:
Left block is on surface with higher inclination so it will go down . If T be tension
For motion of block A ,
net force = mgsin60 - (T + mg cos 60 x μ ) , μ is coefficient of friction .
ma = mgsin60 - T - mg cos 60 x .1
10a = 277.13 - T - 16
= 261.13 - T
T = 261.13 - 10a
For motion of block B
T - mg sin30 - mgcos30 x μ = ma
T- 160 - 27.71 = 10 a
261.13 - 10a - 160 - 27.71 = 10a
73.42 = 20a
a = 3.67 ft / s²
common acceleration = 3.67 ft / s²
The initial velocity is obtained as 2.5 m/s.
<h3>What is the initial speed?</h3>
To obtain the initial speed, we have to apply the law of conservation of linear momentum which states that momentum before collision is equal to momentum after collision.
Now, the two fragments initially had one velocity before they were split in two directions opposite each other;
Applying the principle of conservation of linear momentum to this problem;
(2 + 10)v = (6 * 10) - (2 * 15) (they moved in opposite directions)
12v =60 - 30
12v = 30
v = 30/12
v = 2.5 m/s
