346.70015 m/s
Explanation:
In the x axis speed is
In the y axis
The resultant velocity is given by
The magnitude of the overall velocity of the hamper at the instant it strikes the surface of the ocean is 346.70015 m/s
Answer:
Part A:
The proton has a smaller wavelength than the electron.
<
Part B:
The proton has a smaller wavelength than the electron.
<
Explanation:
The wavelength of each particle can be determined by means of the De Broglie equation.
(1)
Where h is the Planck's constant and p is the momentum.
(2)
Part A
Case for the electron:
But
Case for the proton:
Hence, the proton has a smaller wavelength than the electron.
<em>Part B </em>
For part b, the wavelength of the electron and proton for that energy will be determined.
First, it is necessary to find the velocity associated to that kinetic energy:
(3)
Case for the electron:
but
Then, equation 2 can be used:
Case for the proton :
But
Then, equation 2 can be used:
Hence, the proton has a smaller wavelength than the electron.
Yes they are equivalent because 7x5=35 and 8x x 5=48x
Drag Force = bv^2 = ma; a = g = 9.81 m/s^2
b = mg/v^2 = (0.0023×9.81)/(9.4^2)
b = 0.000255
