Answer:
g / 16
Explanation:
T = 2π 
angular frequency ω = 2π /T
= 
ω₁ /ω₂ = 
Putting the values
ω₁ = ω , ω₂ = ω / 4
ω₁ /ω₂ = 4
4 = 
g₂ = g / 16
option d is correct.
Answer:
The number of people at game are approximately 22909
Explanation:
Given data
When one person shout 
When n number of person shout together 
The sound intensity level during one person shout is given by:

The sound intensity level during n number of person shout is given by:

Since each person generates same sound intensity and hence total number of persons can be determined as

Hence
The number of people at game are approximately 22909
The same number there were on the reactant side, before the reaction.
Explanation:
As we know, resistance is the ratio of voltage used and current flowing through the circuit. So,
<h3>R = V/I</h3>
By error calculation
<h3>∆R/R = [(∆V/V)100] + [(∆I/I)100]</h3>
V = 100 ± 6% V
I = 10 ± 0.2% A
∆R/R= (5/100)×100 + (0.2/10)×100
∆R/R=5+2=7%
<h2>So, percentage error in resistance (R) = ± 7%.</h2>
