Answer:
Explanation:
Electromagnetic waves are different from ocean waves through their mode of propagation
Electromagnetic waves are Those waves that do not requires any material medium for their propagation. examples of electromagnetic waves are, Light wave, radiant heat, radio wave,
While
Ocean Waves are classified under mechanical waves, because they required a material medium for the to be to be propagated.
Answer:
Explanation:
Given that
Wavelength
slit separation
slit screen distance
We know that for double slit the maxima condition is that
For small angle approximation,
Now
Again
Hence
Answer:
Acceleration of the box is 4.9 m/s².
Explanation:
The free body diagram is shown below.
The weight of the body can be resolved into two mutually perpendicular components as shown. The force responsible for sliding motion of the box along the incline is due to acting along the incline.
Therefore, as per Newton's second law of motion,
Net force =
Now, net force acting along the incline is only
Therefore,
Now,
Therefore, the acceleration of the box is given as:
Acceleration of the box is 4.9 m/s².

The complete question is as follows: At 700 K, decomposes to carbon and chlorine. The Kp for the decomposition is 0.76.
Find the starting pressure of at this temperature that will produce a total pressure of 1.1 atm at equilibrium.
Answer: The starting pressure of is 0.79 atm.
Explanation:
The equation for decomposition of is as follows.
Let us assume that initial concentration of is 'a'. Hence, the initial and equilibrium concentrations will be as follows.
Initial: a 0 0
Equilibrium: (a - x) 0 2x
Total pressure = (a - x) + 2x = a + x
As it is given that the total pressure is 1.1 atm.
So, a + x = 1.1
a = 1.1 - x
Now, expression for equilibrium constant for this equation is as follows.
Hence, the value of 'a' is calculated as follows.
a + x = 1.1 atm
a = 1.1 atm - x
= 1.1 atm - 0.31 atm
= 0.79 atm
Thus, we can conclude that starting pressure of is 0.79 atm.
