Answer:
Obviously Lengthen... or
Explanation:
As we can observe from the equation, time period of a simple pendulum depends upon the length directly. When the gravitational acceleration increases the time period of the pendulum decreases and vice versa. So, by increasing the length, the time period can be adjusted...
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
