Answer:
The order of maximum is 
Explanation:
From the question we are told that
The diffraction grating is k = 300 lines per mm = 300000 lines per m
The wavelength is 
Generally the condition for constructive interference is mathematically represented as
Here n is the order maximum
d is the distance the grating which is mathematically represented as
=> 
=> 
So
at maximum 
=> 
=>
Answer:
constant horizontal force developed in the coupling C = 11.25KN

Answer:
Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge
The oceanic crust solidifies faster than the continental crust. Because when magma comes into contact with ocean water it cools faster than when it reaches continental rock. Option C is correct.
<h3>What is the crust?</h3>
The outermost layer of a terrestrial planet is referred to as its "crust."
In the upper mantle, the Earth's crust is constantly melting and solidifying. Compared to magma beneath the continental crust, the oceanic crust has a lower temperature.
Magma cools more quickly when it comes into touch with ocean water than when it hits continental rock. causes the continental crust to solidify more slowly than the oceanic crust.
Hence option C is correct.

To find average speed, we divide the distance of travel (in this case, 400 metres) by the time she took, 32 seconds. Therefore: 12.5 seconds is her average speed.
