Answer:
Minimum uncertainty in velocity of a proton,
Explanation:
It is given that,
A proton is confined to a space 1 fm wide,
We need to find the minimum uncertainty in its velocity. We know that the Heisenberg Uncertainty principle gives the uncertainty between position and the momentum such that,
Since, p = mv
So, the minimum uncertainty in its velocity is greater than . Hence, this is the required solution.
It takes 3 half-lives:
1. 1000 -> 500
2. 500 -> 250
3. 250 ->125
I'm not sure about the Virginia thing so good luck!
And congratulations on being my first answer-person!!
Hello!
A portable DVD player requires six 1.5-volt batteries to operate. If the resistance in the circuit is 7.2 ohms, what is the current?
Data:
We have six 1.5 volt batteries, soon, your tension (V)
V = 1.5 * 6 = 9 Volts
R (resistance) = 7.2 ohms
I (Current intensity) = ? (in Amps)
Solving (Ohm's First Law):
Answer:
The current is 1.25 amps

As we know that in cellular phone all the signals are transmitted by antenna in the form of electromagnetic waves
All these electromagnetic waves are transmitted through the phones and then received as a signal to the receiver of another phone
These signals are then processed and converted into sound which is produced by the phone
So here correct answer will be
<em>C. The cellular telephone transmits information by electromagnetic waves to a receiver which then encodes them and produces sound.</em>
The best conclusion that can be drawn is that D) A current does not flow in the wire
