If a force of 50 N pulled to the left and another 50 N force pulled to the right, what would be the net force on the two trolleys? 0
What would happen if you reduced the force to the left from 50 N to 10 N? 40N
What would happen if you reduced the force to the left from 10 N to zero? 10 N
Hi all,
I think I have to take the formula for pression. rho = F/A -> rho = ma/A but not sure, how to handle it here.
I thought, it should be rho under - rho above = pl*L - pc *a
Solution is: pl *g *a
Hi all,
To find out the tension. First I have to find out the a.
1. step
F = ma
F = (m1+m2) *a
F = (1+3)*a
F = 4*a
F/4 = a
F = 10N + 50 N
F = 60 N
60/4 = 15 m/s^2
2.step
T =( m1/ (m1 + m2)) * F
T = (1/ 1+3) * 60
T = 15 N
But the final result is 20N.
Thanks for your help!
Hi everyone,
I don't know where to start with NaNO3 + NaOH + Zn -> NH3 + Na2ZnO2 + H2O
How to balance it or where should I start? Any tricks?
Kind regards,

Hi everyone,
I just don't get it how to compute the following task. First I have to find out many moles are in 27g of Water.
H2O = 2*1.01 + 16 = 18.02
27g/18.02 = 1.5mol but afterwards how do I find each elements gram?
d is the correct answer.
