Why do stars have names
You are asked to contemplate the concepts of oscillation and periodic motion (or periodic behavior). These lead to the definition of a special kind of periodic motion called simple harmonic motion. For now, let's just think about periodicity (1) and oscillations for the following two scenarios. Your answers will not be marked for correctness. Scenario 1: The motion of the second hand on a clock is:_______ a. periodic but not oscillatory (I.e. the hand does not oscillate or undergo oscillations). b. periodic and also oscillatory. c. not periodic and not oscillatory. d. oscillatory but not periodic. Scenario 2: The motion of a person rocking back and forth on a rocking chair to the beat of a song is:_______ a. periodic but not oscillatory. b. periodic and also oscillatory. c. not periodic and not oscillatory. d. oscillatory but not periodic. Please explain why your answers for the two scenarios are either the same or different. Your answer should include brief definitions of periodic and oscillatory (or oscillations).

What is the apparent magnitude of the brightest star in the Big Dipper?

Answers

Answer: +1.77

Explanation:

Big dipper is the asterism made of seven bright stars in Ursa Major constellation. An asterism a pattern formed by joining the bright stars in the night sky. On the other hand, whole night sky is divided into 88 areas called constellations. These asterisms are used to identify the constellations.

The brightest star of the big dipper is Alioth which is the 32nd brightest star in the night sky. Its apparent magnitude is +1.77.

The magnitude of Alioth ( the brightest star in the big dipper ) is 1.76 and it is about 81 light years distant from Earth.

A planet has a mass of 5.68 x 1026 kg and a radius of 6.03 x 107 m. What is the weight of a 65.0 kg person on the surface of this planet?

Answers

Weight is dependent on both the mass of the object and the gravitational pull of a planet. This is why people weigh differently on other planets, which have a different gravitational force. Using the formula W = G(m1)(m2)/r^2 where:

W = weight or force
G = Gravitational constant (not the same as g) = 6.67x10^-11 m^2/kg^2
m1 = mass of object 1 (person)
m2 = mass of object 2 (planet)
r = radius of planet

This gives a weight of 677.26 Newtons

An unknown fiber sample is found at a crime scene. Forensic scientists measure its index of refraction and obtain a value of 1.48. A suspect's jacket was made of Dacron polyester, his jeans were made of cotton, his shirt was made of rayon, and his tie was made of acetate. Which piece of clothing may match the fiber at the crime scene?Question 12 options:

tie

shirt

jeans

jacket

Answers

The closest refractive index to the one observed is that of rayon, about 1.51. Therefore, the fiber is likely from the suspect's shirt.

Answer:

shirt

Explanation:
