Based on the given data, 452 Hz is the initial frequency. Then multiplied into two, the data rose to 904 Hz. Hence the next frequency data would be 3 x initial f.

Answer:
Solution
Explanation:
First enlist all the variables
then solve using calculator
<u>Answer:</u> 3
H = 45 m ,
time required for the stone
S = u.t+(1/2) g.t²
45 = (1/2) 9.81. t² since u( initial velocity) = 0 ; S =H.
t² = 9.17 s
<em> t = 3.02 s </em>
therefore answer is 3 m/s
<em> if you satisfy with explanation, please give brainiest ; </em>
Answer:
Explanation:
The experimenter is rotating on his stool with angular velocity ω ( suppose )
His moment of inertia is I say
We are applying no torque from outside . therefore , the angular momentum will remain the same
Thus angular momentum L = I ω = constant
Thus we can say I₁ ω₁ = I₂ω₂ = constant
here I₁ is the initial moment of inertia and ω₁ is the initial angular velocity
Similarly I₂ is the final moment of inertia and ω₂ is the final angular velocity
When a been bag is dropped on his lap , his moment of inertia increases due to increase in mass
In the above equation, when moment of inertia increases , the angular velocity decreases . So its motion of rotation will decrease .
Answer:
2A
Explanation:
Voltage = Current * Resistance
V= I*R
I=V/R
I = 24/12 = 2A.
