Answer:
F - w = m a = 2 T - m g net force on man and chair
F = 2 * 368 N = 736 N each rope supports 368 N
a = (736 - 72 * 9.8) / 72 = .422 m/s^2
Answer:
Wavelength, 
Explanation:
Given that,
Width of the slit, 
The angle between the first dark fringes on either side of the central maximum is 34 degrees
To find,
The wavelength of the light used.
Solution,
The equation of maxima is given by :
n = 1 here
So, the wavelength of the light used is 
. Hence, this is the required solution.
Answer:
The question is not complete. Since force is a vector quantity we need to consider the direction of the two forces.
hence if they are acting opposite on the body . then the net force will be 30-10=20N20N
Acceleration=Force/mass
=20/4
=5m/s^2
