We know, F = m*a
Here, F = 600-400 = 200 N downwards
m = 60 Kg
Substitute their values,
a = 200/60
a = 20/6
a = 10/3
a = 3.33 m/s² downwards
In short, Your Answer would be 3.33 m/s² downwards
Hope this helps!

Answer: (A) 3.0=A
Explanation: In order to explain this problem we have to use the OHM law, given by: V=R*I
Besides, we have to consider the resitance equivalent for a parallel connection. This is given by:
1/Re=1/R1+1/R2
If we connect the same resistance, the equivalent resistance is R/2.
Initlally the current is 1.5 A when one resistance is connected to the batttery. When a second resistance with the same value is connected in parallel to the battery, we have V=Re*Ifinal= (R/2)*Ifinal
also we know that V=R*Iinitial so Iinitial=V/R
then Ifinal= 2*V/R=2*Iinitial
So then if they do spill the chemical then it gets on their cloths and not on then it dosen"t harm them instead it ruins their shirt.
