Need help in knowing what energy it’s using
ser-zykov [4K]

Answer:

8:P.E,9:gaining K.E,10:P.E,11:gaining K.E.

Explanation:

it gained potential energy at 8 because it was at its maximum height,and since potential energy is the energy that u posses due to ur height,thats the energy it possesed on the spot 8.as you can see on spot 9 its moving down so as its moving down,it gains kinetic energy,since its an energy possesed by a body due to its motion/movement,thats what it gained at spot 9, it gsained kineti energy because of its movement.and at 10 agian it would gain potential energy ecause of height and on point 11 as its heading upwards it gains kinetic energy because of movement.

The position of an electron is measured within an uncertainty of 0.100 nm. What will be its minimum position uncertainty 2.00 s
Tanya [424]

Answer:

Minimum uncertainty in position is \Delta x= 1157808.48\ m

Explanation:

It is given that,

Uncertainty in the position of an electron, \Delta x=0.1\ nm=0.1\times 10^{-9}\ m

According to uncertainty principle,

\Delta x.\Delta p\geq \dfrac{h}{4\pi}

\Delta x.m\Delta v\geq \dfrac{h}{4\pi}

\Delta v\geq \dfrac{h}{4\pi \times \Delta x\times m}

\Delta v\geq \dfrac{6.62\times 10^{-34}\ J-s}{4\pi \times 0.1\times 10^{-9}\ m\times 9.1\times 10^{-31}\ kg}

\Delta v\geq 578904.24\ m/s

Let \Delta x is the uncertainty in position after 2 seconds such that,

\Delta x=\Delta v\times t

\Delta x=578904.24\ m/s\times 2\ s

\Delta x= 1157808.48\ m

or

\Delta x= 1.15\times 10^6\ m

Hence, this is the required solution.
