5. The diagram below shows a horizontal 8.0-newton force applied to a 4.0-kilogram block on a frictionless
table.
4.0 kg
F = 8.0 N
Frictionless Table
What is the magnitude of the block's acceleration?
A) 0.50 m/s2
B) 2.0 m/s2
C) 9.8 m/s2
D) 32 m/s2

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.

Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.
