Answer:
24 N
Explanation:
Mechanical advantage is the rate of load overcome to the effort applied to overcome the load or resistance. Also, it is the quotient of the resistance force to the effort force.
i.e MA = 
Given that, MA = 4, and L = 6.0 N, then;
4 = 
cross multiply to have
L = 4 x 6
= 24 N
L = 24 N
Thus, the force exerted on the resistance by the machine is 24 N.
Following reaction shows the complete hydrolysis of ketal. The products formed are 1) Diol and 2) Ketone. Mechanism is shown below,
Answer:
2.45×10^54
Explanation:
Mg(s) + Zn2+(aq) = Mg2+(aq) + Zn(s)
From the equation;
n= 2 moles of electrons
E°anode= -2.37 V
E°cathode= -0.76 V
From E°Cell= E°cathode - E°anode
E°Cell= -0.76-(-2.37) = 1.61 V
Recall that E°cell= 0.0592/n log K
1.61= 0.0592/2 log K
log K = 1.61/0.0296
K= Antilog (54.39)
K= 2.45×10^54
