Simple reaction time involves selecting a
specific and correct response from several choices when presented with several
different stimuli. This is very important because historically, this was the
first indicators of intelligence pioneered by Francis Galton. To measure one’s
intelligence is to know how he quick a person could respond to the stimulus
with an already expected response wherein the stimulus is given unknown to the
receiver. In other terms, the intelligence is measured on how quick a person
could grasp certain concepts and how he could think fast and answer them
correctly.

Answer:
<h2>23.33 kg </h2>
Explanation:
The mass of the object can be found by using the formula

f is the force
a is the acceleration
From the question we have

We have the final answer as
<h3>23.33 kg</h3>
Hope this helps you
Explanation:
It is given that,
Mass of the woman, m₁ = 52 kg
Angular velocity, 
Mass of disk, m₂ = 118 kg
Radius of the disk, r = 3.9 m
The moment of inertia of woman which is standing at the rim of a large disk is :


I₁ = 790.92 kg-m²
The moment of inertia of of the disk about an axis through its center is given by :


I₂ =897.39 kg-m²
Total moment of inertia of the system is given by :


I = 1688.31 kg-m²
The angular momentum of the system is :



So, the total angular momentum of the system is 4980.5 kg-m²/s. Hence, this is the required solution.
