Answer:

a). whenever the ball is at it's highest on either side (it stops, so kinetic energy is 0)

b). whenever the ball is at the bottom (A) - it cannot go lower, so potential energy is 0.

c). whenever the ball accelerates, so when it's going down from either side before reaching A (at that point it's going up and thus slowing down).

d). whenever the ball is ascending, so when it's goind up from A to either side

Explanation:

Kinetic energy is based on velocity

E_K = \frac{mv^2}{2}

mass is constant, so we need to find a point where v = 0 to solve a), and points where v is increasing to solve b).

Potential energy is based on height vs "the bottom" (here, the minimum altitude is "the bottom").

E_P = mgh

mass and gravitational acceleration are constant, so we need to find a point where h = 0 to solve b) and the points where h is increasing to solve d).

Explain why does the bowling ball decelerate as it travels along the lane
frutty [35]

The main cause of this is Friction. The more oil that is laid down, the less friction there is between the ball and the lane surface. The less friction, the harder it is for the bowler to send the ball in a curved path imparted by the spin that the bowler puts on the ball at the instant of release.

Which of the following statements is accurate?
cupoosta [38]

Answer: A and B

Explanation:

A

The wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

Because wavelength is the distance between the two successful crest or trough.

B) 

Amplitude of longitudinal waves is measured at right angles to the direction of the travel of the wave and represents the maximum distance the molecule has moved from its normal position.

Because amplitude is the measure of maximum displacement from the original position

Which of the following are important biotic factors that can affect the structure and organization of biological communities?
umka21 [38]

Answer:

c. predation, competition, parasitism

Explanation:

The important and only biotic factors from the given choices that can affect the structure and organization of biological communities are predation, competition and parasitism.

These factors ensures that there are interaction between organisms of the same and different species and only occur in life.

Biotic factors are the living component of the ecosystem that dictates what happens therein.

  • Predation is an interaction between two organisms in which the predator, bigger organism feeds on the prey, smaller organism.
  • Competition occurs where two organism of the same or different species struggles for limited resources in the ecosystem.
  • Parasitism is an interaction where one organism feeds on the another and it causes harm to it. The organism feeding on another is called the parasite. And the one it is dependent on is the host.

All of these are biotic factors.
