The atomic symbol mc026-1.jpg represents lead-206 (Pb-206), an isotope that has 82 protons and 124 neutrons. Which atomic symbol could represent an isotope that undergoes radioactive decay to produce Pb-206?

Answers

Answer : The atomic symbol represent an isotope that undergoes radioactive decay to produce Pb-206 can be, Polonium (Po).

Explanation :

Alpha decay : In this process, the alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units.

The general representation of alpha decay,

$_A^Z\textrm{X}\rightarrow _(A-2)^(Z-4)Y+_2^4\alpha$

The balanced nuclear reaction for alpha decay of polonium-210,

$_(84)^(210)\textrm{Po}\rightarrow _(82)^(206)Pb+_2^4\alpha$

Hence, the atomic symbol represent an isotope that undergoes radioactive decay to produce Pb-206 can be, Polonium (Po).

The source of the centripetal force that arises when a runner rounds a curve on a track is _____.tension
friction
weight
gravity

Answers

while taking a turn on a track, the track provides the frictional force acting towards the center of the curve. we know that to move in a curve, centripetal force is required. here since the frictional force acts towards the center, it provides the necessary centripetal force to move in circle. hence the correct choice is

friction

It's actually Friction.

A car climbs 10.0 kilometers up a hill that inclines 8.0 degrees. What is the car's vertical displacement?

Answers

The correct answer to the question is : $1.392\ Km$

CALCULATION:

The angle of inclination of the hill with the horizontal ground $\theta =\ 8^(0)$ .

The magnitude of displacement or the distance travelled by the car up that hill is given as -

distance S = 10.0 Km.

We are asked to calculate the vertical displacement.

Applying vector resolution process, we get-

(a) $Scos\theta$ is the horizontal component

(b) $Ssin\theta$ is the vertical component.

Hence, the vertical displacement is calculated as -

Vertical displacement $S_(y) =\ S\sin\theta$

$=\ 10* sin8^(0)$

= 1.392 Km.

Hence, the vertical displacement of the car is $1.392\ Km$

I don't understand the physics work power and energy unit

Answers

Work and energy are the same thing. Their unit is the Joule.
One joule means the energy it takes to push with a force of 1 newton
through a distance of 1 meter.

The unit of power is the Watt. That's the rate of work or energy.
One watt means using 1 joule of energy (for example, push with a force of
1 newton through a distance of 1 meter), and doing that in exactly 1 second.
