The answer is;
first blank-
A
Second blank-
B
Activation energy raised the potential energy of reactants to begin a chemical reaction. This requires an initial input of energy into the reaction before the reaction can then proceed spontaneously. That delta G of the activation energy is usually positive. This activation energy destabilized the stable bonds of the reactants so they can form new bonds. This results to a transition state that is a high-energy state.

Explanation:
The magnetic field at distance 'r' from the center of toroid is given by:
a).
b).
The distance is the radius add the cross section so:
Answer:
(A) 2.4 N-m
(B)
(C) 315.426 rad/sec
(D) 1741.13 J
(E) 725.481 rad
Explanation:
We have given mass of the disk m = 4.9 kg
Radius r = 0.12 m, that is distance = 0.12 m
Force F = 20 N
(a) Torque is equal to product of force and distance
So torque , here F is force and r is distance
So
(B) Moment of inertia is equal to
So
Torque is equal to
So angular acceleration
(C) As the disk starts from rest
So initial angular speed
Time t = 4.6 sec
From first equation of motion we know that
So
(D) Kinetic energy is equal to
(E) From second equation of motion
