The magnitude of Alioth ( the brightest star in the big dipper ) is 1.76 and it is about 81 light years distant from Earth.
Answer:
The speed is 26.5 m / s and 29.9º
Explanation:
This is a kinematic problem, let's look at the speed in the x direction, after the RCS shutdown time
Vfx = Vox + a t
Initially there was no velocity on the x-axis, which implies that Vox = 0
Vf = at
Vf = 0.240 58.7
Vfx = 13,872 m / s
The magnitude of the velocity, we can find it using the Pythagorean theorem
V² = Vy² + Vx²
V = √ (24.1² + 13,872²)
V = 26.48 m / s
The direction can be found by trigonometry, as we are asked for the angle measured with respect to the axis and
Tan θ = Vx / Vy
θ = tan -1 (13,872 / 24.1)
θ = 29.9º
The speed is 26.5 m / s and 29.9º

The two speakers emit sound that is 180° out of phase and of a single frequency,ƒ, Find the lowest two frequencies that produce a maximum sound intensity at the positions of Moe and Curly.
answer : 1316.2 hertz
Explanation:
The frequency that produce the maximum sound intensity can be calculated using the relation below
dsin ∅ = n <em>A</em>
where <em>A = </em>dsin ∅ / n when n = 1 . d = 0.800
<em>A</em> = 0.800 * ( 1 / 3.162 )
<em>A</em> = 0.253 m
speed of sound = 333 m/s
frequency = speed /<em> A</em>
<em>= </em>333 / 0.253 = 1316.2 hertz
Answer:
C) Amplitude.
Explanation:
By definition, the amplitude of wave is defined as the distance from the rest position to the highest or lowest point of the wave.
The highest and lowest points of the wave are called crests and troughs respectively; Therefore, the amplitude of the waves is also said to be the height of the wave from its rest position to its crest—and also the height of the from the rest position it its trough.
This means Choice C (amplitude) is the correct term used to describe the height of a wave from its rest position to its crest.
<em>P.S: Choice A, the crest height, can also be the correct term, but the term ''amplitude'' is often used and is more technical. </em>
Answer:
it's answer is B
A planet is round because of gravity. A planet's gravity pulls equally from all sides. Gravity pulls from the centre to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three -dimensional circle
