Answer:
Clockwise and counter clockwises, depands.
Explanation:
The direction of current in a loop of wire in a magnatic field depands on the direction in which the loop is moved and the applied magnatic field.
this is determined by what is called right hand rule.
I will give one scenario, let's say that the loop is moved upwards and the applied magnatic field is into the page (if you drew the loop in 2D on a piece of paper), in this case the direction would be clockwise.
Ultraviolet has a shorter wavelength than microwaves, so purple also has a shorter wavelength than red.
C is thus the answer
The closure temperature represents the point when isotopes are no longer free to move out of a crystal lattice.
Answer: Option C
<u>Explanation:</u>
The closure temperature can also be termed as blocking temperature. It is mostly used in radiometric dating. As the temperature decreases, below a certain point the isotopes may get freeze in their lattice positions. And there may be slowing of diffusion.
At the closure temperature, that rate of diffusion will be zero as the isotopes will be no longer free to move out of crystal lattice. So, this is termed as closure or blocking temperature. As the isotopes loose their ability to move, their concentration will remain fixed in their position leading to measurement of radiation dating.
Answer:
16.96 m/s
Explanation:
It is the case of projectile motion in which the projectile fires from the ground and again it hit the ground.
The angle of projection is 32 degree and the velocity of projection is 20 m/s
he velocity at the maximum height is equal to the horizontal component of velocity which always remains constant as there is no acceleration along x axis.
Velocity at the highest point = u Cos 32 = 20 x Cos 32 = 16.96 m/s
