Depends what you want . 1 it belongs to hydrides , it is nitrogen hydride . 2 if you want to use the property given ( and i presume you mean pH ) then it is a base . 3 because it is a soluble base , it is called an alkali .
Answer:
★The second law of refraction
The ratio of sine of angle of incidence to the sine of angle of refraction is a constant for a light of given colour and for a given pair of media. This law is also called Snell's law of refraction. If 'i' is the angle of incidence and 'r' is the angle of refraction then, Sin i/Sin r = constant
This constant value is called the refractive index of the second medium with respect to the first.
Answer:
A body will become positively charged when some electrons will come out from the body.Thus, positive charge is due to deficiency of electrons.
Answer:
B) The amount of time the torque is applied to the disk, because the time interval is related to the angular impulse of the disk.
Explanation:
Angular impulse = Torque x time
= change in angular momentum
So,
Torque x time = change in angular momentum
change in angular momentum = Torque x time
Torque is already known .
Hence to know the change in angular momentum what is needed to know is time duration of torque acting on the body .
