Type O stars have shorter lives than type G stars.
Part b
To evaluate: The following prediction.
Type K supergiant stars produce iron before they explode as supernovae.
Part c
To evaluate: The following prediction:
Type F stars become much more luminous near the ends of their lives than they were as main-sequence stars.
Part d
To evaluate: The following prediction:
Type O stars do not become more luminous near the ends of their lives but do become redder.
Part e
To evaluate: The following prediction:
Type M stars should have longer lives than type K stars.
Part f
To evaluate: The following prediction:
Stars similar to Sun reach a maximum size of about 100 solar radii during the red giant stage.

- Q9: When a wedding ring is thrown horizontally out of a fifth-floor window 15 m off the ground, it lands 7.5 m out from the base of the building. Calculate the throwing speed; (a) (b) the impact velocity; (c) how long the marriage will last. Q10: A girl on a sled with a combined mass of 50.0- kg slides down a frictionless hill from rest. When she gets to the bottom of the hill, she is traveling at 3.00 m/s. How high is the hill?" m = 50.0 kg HILL v, 3.00 m/s ■ 0 (ground)arrow_forwardThis is data I collected from a Centripetal Acceleration and Force lab.

- A coin is located 20.0 cm to the left of a converging lens. (f=13.0cm). A second, identical lens is placed to the right of the first lens, such that the image formed by the combination. has the same size and orientation as the original coin. Find the separation between the lenses.arrow_forwardA converging lens (f₁ = 10.9cm) is located 33.0 cm to the left of a diverging lens (f2=-5.64 cm). A postage stamp is placed 35.4 cm to the left of the converging lens. Find the overall magnificationarrow_forwardA farsighted man uses contact lenses with a refractive power of 2.00 diopters. Wearing the contacts, he is able to yead books held no closer than 25.0 cm from would like a his eyes. He prescription for eyeglasses to serve the same purpose. What is the correct prescription for the eyeglasses if the distance from the eyeglasses to his eyes is 200 cm 2.00 dioptersarrow_forward

A ray of light is incident on the glass at point A with a O₁ = 47.0° angle of incidence. At what angle of refraction does the ray leave the glass at point B? A Barrow_forwardThere is a magic item in Dungeons & Dragons called The Baton of Many Sizes, which is a staff that can magically change lengths between 0.305 m (1 foot) long and 15.2 m (50 feet) long, though it always has a mass of 3.18 kg. Assume the moment of inertia of the staff is 112mL2112mL2 where L is the total length. The angular acceleration is 4.9075 rad/s^2, the angular velocity is 17.57 rad/s. The staff then shrinks to a length of 1.12 m while no longer applying any torque. What is the staff’s new angular velocity?arrow_forward

Samus rolls down a path which drops down 22.0 m. If she was at rest when she started at the top, what is her linear velocity at the bottom of the path? Treat her as a solid sphere with a moment of inertia of 2/5 mr^2 .arrow_forwardMoon Knight, from both comics and the show of the same name, has crescent shaped daggers he throws at enemies. To throw a crescent dagger he applies a force of 0.918 N at an angle of 75.0° relative to the dagger’s center of mass at a point 0.0690 m away from the dagger’s center of mass. If the crescent dagger has a moment of inertia of 2.57⋅10^−5 kg⋅m^2 , what is the angular acceleration of a crescent dagger as it is thrown?arrow_forward
