Answer:
Long question good luck:)
Explanation:
Answer:
induced electromotive force (Voltage) E = - N dΦ / dt
Explanation:
When the magnetic flux this coil induces a current in each turn of the coil, which is why an induced electromotive force (Voltage) appears at the ends of the coil.
This phenomenon is fully explained by Faraday's law
E = - dΦ / dt
where in the case of a coil with N turns of has
E = - N dΦ / dt
Rl flux is the product of the normal to the area by the magnetic field, in this case the flux changes so we can assume that the area of the coil is constant
Answer: b
Explanation:
B is a chemical property
Reference what are physical properties
And what are chemical properties
Under certain conditions it can release a gas is the key words letting you know this is a chemical property
Mercury has a high boiling point of 357 degrees C.
Mercury has a freezing point of −39 degrees C.
Answer: a. forms where light rays coming from the dog converge.
Explanation:
While photographing through digital camera, the light from the object through the lens converges and falls on image sensor.
The image breaks into many pixels and color and brightness of each pixel is measured and stored in form of number. This forms a digital image.
Thus, the correct option is a because the lens converges the light coming from the object onto the sensor.
