A)
Atmospheric pressure is 101325 Pa.
Pressure = Force / Area
Area of table = 1.5 x 2.2
= 3.3 m²
Force = 101325 x 3.3
= 334 kN
B)
According to Newton's third law, every action has an equal and opposite reaction. Thus, the upward force is equal to the force acting downward on the table and is being balanced. The force is 334 kN in the upward direction.
Part A)
Distance is given as sum of total path length
So here as we are given that car drives 40 miles East and 30 miles West
So here the total path length is


Part B)
Displacement is given as straight line distance between initial and final position
So here we can see that
East
West
Now the total displacement will be

<u><em>so the displacement will be 10 miles East</em></u>
Answer:
hide on a place where there is no windows take a radio
Explanation:
Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Explanation:
Answer:
The the intensity at an 11° angle to the axis in terms of the intensity of the central maximum is

Explanation:
From the question we are told that
The width of the slit is 
The wavelength is 
The angle is 
The intensity of at
to the axis in terms of the intensity of the central maximum. is mathematically represented as
![I_c = \frac{I}{I_o} = [ \frac{sin \beta }{\beta }] ^2](https://tex.z-dn.net/?f=I_c%20%3D%20%5Cfrac%7BI%7D%7BI_o%7D%20%20%3D%20%5B%20%5Cfrac%7Bsin%20%5Cbeta%20%20%7D%7B%5Cbeta%20%7D%5D%20%5E2)
Where
is mathematically represented as

substituting values


So
![I_c = \frac{I}{I_o} = [ \frac{sin (708.1) }{(708.1)}] ^2](https://tex.z-dn.net/?f=I_c%20%3D%20%5Cfrac%7BI%7D%7BI_o%7D%20%20%3D%20%5B%20%5Cfrac%7Bsin%20%28708.1%29%20%20%7D%7B%28708.1%29%7D%5D%20%5E2)
