Answer:
The magnitude of is 4 V and phase of input voltage is zero
Explanation:
Given:
Output voltage
Resistance kΩ
Voltage gain
For finding feedback resistance we use gain equation
Gain equation for non inverting op-amp is given by,
≅ 10 kΩ
For finding input voltage we use,
V
The Phase of is zero because output voltage phase is 360°
Therefore, the magnitude of is 4 V and phase of input voltage is zero
Answer:
0.143 m
Explanation:
The relationship between force applied on a string and stretching of the spring is given by Hooke's law:
where
F is the force exerted on the spring
k is the spring constant of the spring
x is the stretching of the spring from its equilibrium position
In this problem, we have:
F = 20 N is the force applied on the spring
k = 140 N/m is the spring constant
Solving for x, we find how far the spring will stretch:
The book's vertical position in the air is
where . It reaches the ground when
, at a time
such that
So it takes the book 4 seconds to reach the bottom. The given initial velocity is irrelevant since it only has a horizontal component; vertically, the book is starting from rest.
