The x-component of vector R is Rx = −28.2 units and its y-component is Ry = 19.6 units. What are its magnitude and direction? Gi
ikadub [295]

Answer:

Explanation:

Rx = -28.2 units

Ry = 19.6 units

magnitude of R = √  [( - 28.2 )² + ( 19.6 ) ]

= √ ( 795.24 + 384.16 )

= 34.34 units

If θ  be the angle measured counterclockwise from the +x-direction

Tanθ = 19.6 / - 28.2 = -0.695

θ = 180 - 34.8

= 145.2° .

According to Heisenberg's uncertainty principle, the more we know about a particle's momentum, the less we know about its ______
Hoochie [10]

Answer:

location.

Explanation:

Heisenberg uncertainty principle states that it is basically impossible to know the exact position and momentum of a particle at the same time. According to my research on this principle, I can say that based on the information provided within the question the more we know of the momentum the less we know about it's location.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

A car accelerates from 6.00 m/s to 20.0 m/s, over a distance of 50.0 m. what is its rate of acceleration?
Kitty [74]
<span>v² = u² + 2as </span>
2as = v² - u² 
<span>a = (v² - u²) / 2s </span>

<span>a = (20.0² m²/s² - 6.00² m²/s²) / (2 * 50.0 m) </span>
<span>a = (400 m²/s² - 36 m²/s²) / (100 m) </span>
<span>a = (364 m²/s²) / (100 m) </span>
a = 3.64 m/s²
