Answer:
<em>A = 0.05 V</em>
Explanation:
<u>Sinusoidal Functions</u>
A sinusoid or sinusoidal function is a sine or cosine which general equation is

Or also

Where A is the amplitude or maximum value, w is the angular frequency, t is the time and
is the phase shift.
Comparing the given expression with the general formula

We can establish that A=50 mV = 0.05 V

Answer:
If the ship speed is doubled, then the power developed is 8 times the initial value.
Explanation:
ship power is roughly proportional to the cube of the speed, so
P ∝ v³
If the speed is doubled, then the power developed becomes
P ∝ (2)³ = 8 times
Therefore, if the ship speed is doubled, then the power developed is 8 times the initial value.
Answer:
q = 3.6 10⁵ C
Explanation:
To solve this exercise, let's use one of the consequences of Gauss's law, that all the charge on a body can be considered at its center, therefore we calculate the electric field on the surface of a sphere with the radius of the Earth
r = 6 , 37 106 m
E = k q / r²
q = E r² / k
q =
q = 4.5 10⁵ C
Now let's calculate the charge on the planet with E = 222 N / c and radius
r = 0.6 r_ Earth
r = 0.6 6.37 10⁶ = 3.822 10⁶ m
E = k q / r²
q = E r² / k
q =
q = 3.6 10⁵ C
politics. Famous possible eg is of Werner Heisenberg in WW2. He delayed German attempt to build a nuclear bomb. US did build one ... hiroshima and nagasaki.

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
.
