Answer and Explanation:
Hydrostatic equilibrium is the condition in which force is balance that is upward force and downward force the downward force is due to gravitational force and the upward force is due to the pressure. The Sun is said to be in hydrostatic equilibrium means the force acting on it is balance means upward force which is due to pressure is same as the force exerted by gravitation.

i know if its right but hope this helps :)
Answer:
is the environment in which users run application software. The environment consists of a user interface provided by an applications manager and usually an application programming interface (API) to the applications manager.
Answer:
For one dimensional box
E= 
For lowest energy transition will be from n =1 to n=2
Hence,
h= 6.626 *10-34 J.s
m = 9.31 *10-31 Kg
L= 0.14 * 10-9 m
c= 3 *108 m/s
Not in visible range
Answer:
5.9 m/s²
78 N
Explanation:
Draw a free body diagram for each mass.
The mass on the left (M) has a tension force pulling up (T) and a weight force pulling down (Mg).
The mass on the right (m) has a tension force pulling up (T) and a weight force pulling down (mg).
Apply Newton's second law to the mass on the left (remember it accelerates down):
∑F = ma
T − Mg = M (-a)
T − Mg = -Ma
Apply Newton's second law to the mass on the right:
∑F = ma
T − mg = ma
Two equations, two unknowns (T and a). First, we want to find a. So start by subtracting the first equation from the second equation.
(T − mg) − (T − Mg) = ma − (-Ma)
T − mg − T + Mg = ma + Ma
Mg − mg = (m + M) a
a = g (M − m) / (m + M)
Given M = 20 kg and m = 5 kg:
a = 9.8 m/s² (20 kg − 5 kg) / (5 kg + 20 kg)
a = 5.88 m/s²
Now plug into either equation to find the tension.
T − mg = ma
T = mg + ma
T = m (g + a)
T = (5 kg) (9.8 m/s² + 5.88 m/s²)
T = 78.4 N
Rounding to two significant figures, the acceleration and tension are 5.9 m/s² and 78 N.
Notice that the radius of the pulley and the distance between the masses were extra information.
