Answer: The ball would have the most kinetic energy at the lowest point and the most potential energy at the top of the hill

Explanation:

Since you didnt add the picture I cant tell which multiple choice answer it would be, but I hope this helps :)

g suppose he used an alpha particle with an energy of 8.3 MeV, what would be the speed of this alpha particle
mixas84 [53]

Answer:

<em>speed of the alpha particle is 2 x 10^7 m/s.</em>

Explanation:

energy of alpha particle = 8.3 Mev

1 Mev = 1.602 x 10^-13 J

8.3 Mev = x

solving, x = 8.3 x 1.602 x 10^-13 = 1.329 x 10^-12 J

mass of a alpha particle = 6.645 x 10^−27 kg

The energy of the alpha particle is the kinetic energy KE of the alpha particle

KE = \frac{1}{2}mv^{2}

where m is the mass of the alpha particle

v is  the velocity of the alpha particle

substituting values, we have

1.329 x 10^-12 = \frac{1}{2}*6.645*10^{-27}*v^{2}

v^{2} = 4 x 10^14

v = \sqrt{4*10^{14} } = <em>2 x 10^7 m/s</em>

During anomalous expansion of water ,heat transfer is limited to conduction and radiation only ,explain.​
aalyn [17]

Heat transfer is limited to conduction and radiation only in anomalous expansion of water simply because of the temperature at which the expansion occurs and density

<h3>What is anomalous expansion of water?</h3>

Anomalous expansion of water is a property of water in which water expands instead of contracting.

  • Anomalous expansion of water makes water less dense.
  • The major effect of this anomalous expansion it will still remain less dense and at the surface of water.
  • Interestingly, this expansion occurs when it is cooled from 4°C to 0°C.
