A system has two possible energy states, E0 and E1 (with E1 > E0). If the difference between these energy states grows (E0 an

Ugo [173]

Answer:

The number of particles in state E0 over the number of particles in state E1 will reduce

Explanation:

E0 represents the ground level state when all the particles have same energy level.

E1 represents excited state in which only a few particle reaches

E0 and E1 get further apart means that the energy difference between the two level increases.

Thus, the number of particles in state E0 over the number of particles in state E1 will reduce.

Ek=8J m=100g V=? How much is V going to be? Explain step by step, please

Darya [45]

Answer:

Explanation:

If Ek is the kinetic energy and m is the mass and v is the velocity then v can be calculated as follows

Ek= 1/2 ×( m × v² )

2Ek= mv²

2Ek/m = v²

v =√(2Ek/m)

m = 0.1 kg

v= √(2x8/0.1)= 12.65 m/s

An 800-N billboard worker stands on a 4.0-m scaffold weighing 500 N and supported by vertical ropes at each end. How far would t

Lynna [10]

Answer:

2.5 m

Explanation:

Weight of billboard worker = 800 N

Number of ropes = 2

Length of scaffold = 4 m

Weight of scaffold = 500 N

Tension in rope = 550 N

The sum of the torques will be

$-800(4-x)-500\times 2+550\times 4=0\\\Rightarrow -800(4-x)=500\times 2-550\times 4\\\Rightarrow -800(4-x)=-1200\\\Rightarrow -x=\dfrac{1200}{800}-4\\\Rightarrow -x=-2.5\\\Rightarrow x=2.5\ m$

The position of the person will be 2.5 m
