A 190 g block is pressed against a spring of force constant 1. 60 kn/m until the block compresses the spring 10. 0 cm. The spring rests at the bottom of a ramp inclined at 60. 0° to the horizontal. Using energy considerations, determine how far up the incline (in m) the block moves from its initial position before it stops under the following conditions.
How far up the incline (in m) the block moves from its initial position before it stops is 4.96 m
Law of conservation of energy
From the law of conservation of energy, the total mechanical energy at the bottom of the incline, E equals the total mechanical energy when the mass stops, E'
So, E = E'
U + P + K = U' + P' + K' where
U = initial elastic potential energy = 1/2kx² where k = spring force constant = 1.60 kN/m = 1.60 × 10³ N/m and x = spring compression = 10 cm = 0.1 m, P = initial gravitational potential energy = 0 J, K = initial kinetic energy = 0, U' = final elastice potential energy = 0, P' = final gravitational potential energy = mgh where m = mass of block = 190 g = 0.190 kg, g = acceleration due to gravity = 9.8 m/s² and h = vertical height block moves and K' = final kinetic energy = 0 (both kinetic energies are zero since the body is at rest at both positions)Substituting the values of the variables into the equation, we have
U + P + K = U' + P' + K'
1/2kx² + 0 + 0 = 0 + mgh + 0
1/2kx² = mgh
Vertical height block moves
making h subject of the formula, we have
h = kx²/2mg
substituting the values of the variables into the equation, we have
h = kx²/2mg
h = 1.60 × 10³ N/m(0.1 m)²/(2 × 0.190 kg × 9.8 m/s²)
h = 1.60 × 10³ N/m × 0.01 m²/(3.724 kgm/s²)
h = 16.0 Nm/(3.724 kgm/s²)
h = 4.296 m
Distance up the incline the block moves
Now, the distance up the incline the block moves is L = h/sinФ where
h = vertical height block moves = 4.296 m and Ф = angle of incline = 60.0°Substituting the values of the variables into the equation, we have
L = h/sinФ
L = 4.296 m/sin60.0°
L = 4.296 m/0.8660
L = 4.96 m
So, how far up the incline (in m) the block moves from its initial position before it stops is 4.96 m

Which of the following is expected to happen to a species' population when resources are stable over a long period of time and the species have reached carrying capacity?.
Answer:
1: The population will decrease
2: decrease in predators
3: 9
4: decrease in prey -> decrease in predators -> increase in Prey
5: natality-mortality = immigration-emigration
Explanation:
The population will decrease as it gets stable over a period of time.
What is carrying capacity ?The carrying capacity refers to the maximum population the ecosystem or the environment is able to carry or hold on to. This refers to the max population that can be sustained in the ecosystem and is population dynamics can be modeled from the logistic function. The more the number of species the fewer chances are in their survival as they have reached stability.
