A bowler throws a ball down the lane toward the pins. The ball reaches the pins and slowly moves through them, knocking down the

center pins but leaving the end pins standing. The bowler wants the ball to reach all the pins. Which changes should the bowler make so that the ball has a greater acceleration?(1 point)
The bowler should choose a ball with less mass or throw the ball with more force.

The bowler should choose a ball with more mass or throw the ball with more force.

The bowler should choose a ball with less mass or throw the ball with less force.

The bowler should choose a ball with more mass or throw the ball with less force.

Answer:

First one

Explanation:

Maybe because example if a ball that has less mass bounces higher than the one w/more , then a bowling ball should be able with more force.

hope that helped:/

(b) The particle displacement y of air molecules due to a sound wave is given by y 4m and w = = 0.008 cos wt sin kz. Where k - m
serious [3.7K]

The distance between two consecutive nodes and the amplitude after 0.56s are m/2 and 1.75×10^(-4) m respectively.

<h3>What's the distance between consecutive nodes of the displacement of air molecules?</h3>
  • Wavelength is the distance between two consecutive nodes or toughs or crests or anti-nodes.
  • So, distance between consecutive nodes = wavelength = 2π÷k

= 2π/(4π÷m)

= m/2

<h3>What's the amplitude after 0.56s of the displacement of air molecules?</h3>

Displacement after 0.56 s = 0.008×cos(50π×0.56s)

=1.75×10^(-4) m

Thus, we can conclude that the distance between consecutive nodes and displacement after 0.56 s are m/2 and 1.75×10^(-4) m respectively.

What has been happening to the cosmic microwave background radiation since the Big Bang?​
kondor19780726 [428]

Answer:

Explanation:

Cosmologists refer to a "surface of last scattering" when the CMB photons last hit matter; after that, the universe was too big. So when we map the CMB, we are looking back in time to 380,000 years after the Big Bang, just after the universe was opaque to radiation. But the CMB was first found by accident.
