Answer:
Explanation:
= Uncertainty in position = 1.9 m
= Uncertainty in momentum
h = Planck's constant = 
m = Mass of object
From Heisenberg's uncertainty principle we know
The minimum uncertainty in the momentum of the object is
Golf ball minimum uncertainty in the momentum of the object
Uncertainty in velocity is given by
The minimum uncertainty in the object's velocity is
Electron
The minimum uncertainty in the object's velocity is .
The <em>gaseous state</em> of matter does that. A gas expands to take the shape and volume of whatever you put it into.
Answer:
E = 1440 kJ
Explanation:
It is given that,
Power of a cooker oven is 800 W
Voltage at which it is operated is 230 V
Time, t = 30 minutes = 1800 seconds
We need to find the electrical energy used by the cooker oven. The product of power and time is equal to the energy consumed. So,
So, electrical energy of 1440 kJ is consumed by the cooker oven.
In technical terms, every coil of wire increases the "magnetic flux density" (strength) of your magnet.
So it's A (magnetic field increase)
For a wave is described by y=0.0200 sin (kx - ωt) , where , ω = 3.62 rad/s, x and y are in meters, and t is in seconds, the wavelength = 2.978
<h3>How to solve for the wavelength</h3>
What is wave speed?
This is used to refer to the speed at which a wave is moving. It is the product of frequency and wave number
Given data
y=0.0200 sin (kx - ωt)
ω = 3.62 rad/s
y are in meters
t is in seconds
k = 2.11 rad/m
k = wavenumber = 2 * pi / wavelength
wavelength = 2 * pi / wavenumber
wavelength = 2 * pi / 2.11
wavelength = 2.978
