Answer:

Voltage across element X is 49.26 volts

Explanation:

The kirchhoff's voltage law states that the algebraic sum of voltages around a closed loop is equal to zero.

Applying the kirchhoff's voltage law in loop yields,

-160 + V₁ + V₂ + V₃ + Vₓ + 60 + V₄ = 0

-160 + 60 + V₁ + V₂ + V₃ + Vₓ + V₄ = 0

But we know that V = IR

-100 + IR₁ + IR₂ + IR₃ + IRₓ + IR₄ = 0

IR₁ + IR₂ + IR₃ + IRₓ + IR₄ = 100

I(R₁ + R₂ + R₃ + Rₓ + R₄) = 100

I = 100/(R₁ + R₂ + R₃ + Rₓ + R₄)

Substitute the given resistor values

I = 100/(18k + 20k + 45k + 100k + 20k)

I = 100/203k

I = 100/203×10³

I = 0.0004926 A

The voltage drop at element x is

Vₓ = IRₓ

Vₓ = 0.0004926*100×10³

Vₓ = 49.26 V

Given a mass-spring-damper system. The impulse response of strength 1 can be obtained from a unit step response by: ______

Alina [70]

Answer:

Multiplying impulse response by t ( option D )

Explanation:

We can obtain The impulse response of strength 1 considering a unit step response by Multiplying impulse response by t .

When we consider the Laplace Domain, and the relationship between unit step and impulse, we can deduce that the Impulse response will take the inverse Laplace transform of the function ( transfer ) . Hence Multiplying impulse response by t will be used .

Gas is kept in a 0.1 m diameter cylinder under the weight of a 100 kg piston that is held down by a spring with a stiffness k =

Artyom0805 [142]

Answer:

The spring is compressed by 0.275 meters.

Explanation:

For equilibrium of the gas and the piston the pressure exerted by the gas on the piston should be equal to the sum of weight of the piston and the force the spring exerts on the piston

Mathematically we can write

$Force_{pressure}=Force_{spring}+Weight_{piston}$
