Answer:
Work is the energy required to move an object from one point to another. while power is the energy transferred per unit time.
Energy can also be defined as the ability to do work.

<u>Option</u><u> </u><u>A</u><u>:</u><u> </u><u>1</u><u>9</u><u>.</u><u>5</u><u> </u><u>W</u></h3>
Power of TV = 65Watt
If Efficiency = 70%, then the percentage of energy wasted is 30%
So, the amount of energy getting wasted:
= 30/100 × 65
= 1950/100
= 195/10
= 19.5 W
Answer:
![\Delta x = 1.807 \times 10^{-10}m](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%201.807%20%5Ctimes%2010%5E%7B-10%7Dm)
Explanation:
mass of proton, m = 1.67 x 10^-27 kg
speed of proton, v = 350 km/s = 350,000 m/s
Momentum of proton, p = mass x speed
p = 1.67 x 10^-27 x 350000 = 5.845 x 10^-22 kg m /s
uncertainty in momentum, Δp = 0.1 % of p
Δp = ![\frac{0.1\times 5.845 \times 10^{-22}}{100}=5.845 \times 10^{-25}](https://tex.z-dn.net/?f=%5Cfrac%7B0.1%5Ctimes%205.845%20%5Ctimes%2010%5E%7B-22%7D%7D%7B100%7D%3D5.845%20%5Ctimes%2010%5E%7B-25%7D)
According to the principle
![\Delta x\times \Delta p \geq \frac{h}{2\pi }](https://tex.z-dn.net/?f=%5CDelta%20x%5Ctimes%20%5CDelta%20p%20%5Cgeq%20%20%5Cfrac%7Bh%7D%7B2%5Cpi%20%7D)
where, Δx be the uncertainty in position
![\Delta x\times 5.845 \times 10^{-25}= \frac{6.634 \times 10^{-34}}{2\times 3.14}](https://tex.z-dn.net/?f=%5CDelta%20x%5Ctimes%205.845%20%5Ctimes%2010%5E%7B-25%7D%3D%20%20%5Cfrac%7B6.634%20%5Ctimes%2010%5E%7B-34%7D%7D%7B2%5Ctimes%203.14%7D)
![\Delta x = 1.807 \times 10^{-10}m](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%201.807%20%5Ctimes%2010%5E%7B-10%7Dm)
