An airplane flies due north at 100 m/s through a 30 m/s cross wind blowing from the east to the west. Determine the resultant ve

Ghella [55]

Vf=√30²+100²
Vf=104 m/s

|Ф|=tan inverse of |100÷30|
Ф= 73 degrees

Therefore the resulting velocity of the airplaine is 104 m/s [ 73 degrees N of W]

No electron with a de Broglie wavelength of 2 μm can not pass through a slit that is 1 μm wide

When studying quantum mechanics, the de Broglie wavelength is a key idea. De Broglie wavelength is the wavelength () that is connected to an item in relation to its momentum and mass. Typically, a particle's force is inversely proportional to its de Broglie wavelength.

Where "h" is the Plank constant, momentum has the formula = h m v = h. The de Broglie equation and de Broglie wavelength are terms used to describe the relationship between a particle's momentum and wavelength. The probability density of locating an object at a specific location in the configuration space is determined by the De Broglie wavelength, which is a wavelength present in all quantum mechanical objects. A particle's momentum and de Broglie wavelength are inversely related.

A hockey puck slides off the edge of a horizontal platform with an initial velocity of 28.0 m/shorizontally in a city where the

kozerog [31]

Answer:

θ = 12.60°

Explanation:

In order to calculate the angle below the horizontal for the velocity of the hockey puck, you need to calculate both x and y component of the velocity of the puck, and also you need to use the following formula:

$\theta=tan^{-1}(\frac{v_y}{v_x})$ (1)
