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
Explanation:
A light bulb changes electrical energy into <em>heat energy and light energy .</em>
To solve this problem we will apply the concept related to the magnetic dipole moment that is defined as the product between the current and the object area. In our case we have the radius so we will get the area, which would be



Once the area is obtained, it is possible to calculate the magnetic dipole moment considering the previously given definition:



Therefore the magnetic dipole moment is 
Answer:
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).
Explanation:
Because the particles of a solid are not free to move,
no matter how hot and buoyant they become.
