5. A star reaches 'breakup' when the centrifugal acceleration at its equator becomes equal to the...
answer should be 3 minutes for the first one and 10 seconds for the second one...how? Part II. Questions 1. What would be Sun's rotation period if it collapsed to a radius of 6000 km? How would the Sun's density change? (HINT: Conserve angular momentum. The moment of inertia of sphere is 0.4MR. 2. A star reaches "break-up” speed when it rotates so rapidly that the centrifugal acceleration at its equator equals the surface gravity (g). Estimate the rotation period...
Acceleration due to gravity on board of your spaceship that orbits Jupiter is 25.89 m/s. How high is your spaceship above Jupiter's cloud tops? Express your answer in kilometers and round it to the nearest integer. M Jupiter = 1.90 x 104 kg; R Jupiter = 69,911 km. Your cosmic journey brought you into the vicinity of a neutron star. In fact, you are orbiting this neutron star at an orbital distance of 22.424 kilometers. The neutron star has mass...
Parallel Axis Theorem: I = ICM + Md Kinetic Energy: K = 2m202 Gravitational Potential Energy: AU = mgay Conservation of Mechanical Energy: 2 mv2 + u = žmo+ U Rotational Work: W = TO Rotational Power: P = TO Are Length (angle in radians, where 360º = 2a radians): S = re = wt (in general, not limited to constant acceleration) Tangential & angular speeds: V = ro Frequency & Period: Work-Energy Theorem (rotational): Weet = {102 - 10...
Rotational Dynamics Assignment (200 Points) • Due Friday, July 31 at 5:00 pm Equations are in a separate document entitled “Equations for Rotational Dynamics Assignment” • Moments of inertia formulas are provided on the last page of this document • Show all of your work when solving equations. It is not sufficient to merely have a correct numerical answer. You need to have used legitimate equations and algebra. You also need to have correctly used the data. • Units must...
could you please solve a and b? Chapier 2i. Note: you needn't derive Kepler's laws-but do mention when you are using them, an describe the physical concepts involved and the meanings behind the variables. u) Consider two stars Mi and M; bound together by their mutual gravitational force (and isolated from other forces) moving in elliptical orbits (of eccentricity e and semi-major axes ai and az) at distances 11 in n and r from their center of mass located at...
Many of the bones of the body have an English name as well as a medical name, i.e., skull (cranium). List as many of these as you can. for each multiple-choice question. 1. A cart of mass 4 kg experiences a constant acceleration of 3.0" What is the magnitude of the force exerted on the cart? A. 0.75 N B. 6.0 N C. 2N D3N 2. Displacement vector is 6.0 miles along the negative x-axis and a second displacement vector...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
