Answer:
The correct answer is Option A (decrease).
Explanation:
- According to Heisenberg's presumption of unpredictability, it's impossible to ascertain a quantum state viewpoint as well as momentum throughout tandem.
- Also, unless we have accurate estimations throughout the situation, we will have a decreased consistency throughout the velocity as well as vice versa though too.
Other given choices are not connected to the given query. Thus the above is the right answer.
Answer:
Moment about SHOULDER ∑ τ = 3.17 N / m,
Moment respect to ELBOW Στ= 2.80 N m
Explanation:
For this exercise we can use Newton's second law relationships for rotational motion
∑ τ = I α
The moment is requested on the elbow and shoulder at the initial instant, just when the movement begins.
They indicate the angular acceleration, for which we must look for the moments of inertia of the elements involved
The mass of the forearm with the included weight is approximately 2.3 kg, with a length of about 50cm
Moment about SHOULDER
∑ τ = I α
I = I_forearm + I_sphere
the forearm can be approximated as a fixed bar at one end
I_forearm = ⅓ m L²
the moment of inertia of the mass in the hand, let's approach as punctual
I_mass = m L²
we substitute
∑ τ = (⅓ m L² + M L²) α
let's calculate
∑ τ = (⅓ 2.3 0.5² + 0.5 0.5²) 10
∑ τ = 3.17 N / m
Moment with respect to ELBOW
In this case, the arm exerts an upward force (muscle) that is about 3 cm from the elbow
Στ = I α
I = I_ forearm + I_mass
I = ⅓ m (L-0.03)² + M (L-0.03)²
let's calculate
i = ⅓ 2.3 0.47² + 0.5 0.47²
I = 0.2798 Kg m²
Στ = 0.2798 10
Στ= 2.80 N m
Answer:
<h2>The answer is planetary motion</h2>
Explanation:
According to Johannes Kepler, the laws governing planetary motion
states that:
1. The orbit of a planet is an ellipse with the Sun at one of the two foci.
2. A line segment joining a planet and the Sun sweeps out equal areas
during equal intervals of time.
3. The square of a planet's orbital period is proportional to the cube of the semi-major of its orbit.
Johannes Kepler was a German astronomer, mathematician, and astrologer
Born: 27 December 1571, Weil der Stadt, Germany
Died: 15 November 1630
<span>Chronological essays by the definition of a chronological
meaning in order. There is an order in a specific writing. Like a history write
up from a certain happening years ago. It
is different from procedural essays because these are essays who are giving
instructions of certain set up to guide the person accordingly in doing
something to make it more accurate. Like recipes, instructions in playing, etc.
Example words that are used in chronological essays are first, second, third,
fourth, fifth, next, after, then, lastly, finally, consequently, in addition,
thus, therefore, however, etc.</span>
