Answer:
877
Explanation:
P1 = 150 atm
V1 = 0.12 m^3
P2 = 1.2 atm
V2 = ?
radius of each balloon, r = 0.16 m
Volume of each balloon,
V2 = 0.0171 m^3
Let the number of balloons be N.
So,
P1 x V1 = N x P2 x V2
150 x 0.12 = N x 1.2 x 0.0171
N = 877.19
So, the number of balloons be 877.
Answer:
m = 35.98 Kg ≈ 36 Kg
Explanation:
I₀ = 125 kg·m²
R₁ = 1.50 m
ωi = 0.600 rad/s
R₂ = 0.905 m
ωf = 0.800 rad/s
m = ?
We can apply The law of conservation of angular momentum as follows:
Linitial = Lfinal
⇒ Ii*ωi = If*ωf <em>(I)</em>
where
Ii = I₀ + m*R₁² = 125 + m*(1.50)² = 125 + 2.25*m
If = I₀ + m*R₂² = 125 + m*(0.905)² = 125 + 0.819025*m
Now, we using the equation <em>(I) </em>we have
(125 + 2.25*m)*0.600 = (125 + 0.819025*m)*0.800
⇒ m = 35.98 Kg ≈ 36 Kg
Explanation:
For Gain of −10
Inverting op-amp gain is given by
The negative sign represents output signal being phase shifted by 180°
Ω
For Gain of −1
Ω
For Gain of +10
Non-inverting op-amp gain is given by
Ω
For Gain of +1
To get a Gain of +1, make which results in ∞
The output is directly connected to the input which makes equal to Therefore, giving a gain of exactly 1.
This kind of design configuration is also known as Voltage Follower.
Negative feedback is being used to design these op-amp amplifiers.
Negative feedback increases the stability at the cost of reduced gain.
The gain is reduced by a factor of
Negative feedback reduces noise and distortion and improves frequency response of the amplifier.
An ideal op-amp should have infinite input resistance and zero output resistance. Negative feedback increases the input impedance and reduces the output impedance.
