The diameter of our disk-shaped galaxy, the Milky Way, is about 1.0 105 lightyears (ly). The distance to Messier 31, which is Andromeda, the spiral galaxy nearest to the Milky Way, is about 2.0 million ly. If a scale model represents the Milky Way and Andromeda galaxies as dinner plates 17 cm in diameter, determine the distance between the centers of the two plates. Please provide numerical answer in METERS for 5-star rating.
Find the velocity of each object after the collision.he encountered cold weather conditions on the way to Payson, Utah when the temperature was 23 kelvin lower than in Las Vegas, where he delivered his entire load. how much liters did he deliver.
Now consider this applet, where the two blocks have different masses. Plug the starting values into your formula from Part G, using 5 for mass of the red block and 10 for the magnitude of the acceleration of gravity.
A ski starts from rest and slides down a 22° incline 75 m long. If the coefficient of friction is 0.09, what is the ski's speed at the base of the incline? If there is snow level at foot of the incline and it has the same coefficient of friction, ..
How many J of energy must be removed when 156 g of steam, at a temperature of 175.0 °C, is cooled and frozen into 156 g of ice at 0 °C.
What is the magnitude of an average acceleration of the ball
The human body can survive an acceleration trauma incident (sudden stop) if magnitude of the acceleration is less than 250;{rm m}/{rm s}^{2}.
Your projectile launching system is partially jammed. It can only launch objects with an initial vertical velocity of 42.0 m/s, though the horizontal component of the velocity can vary.
Consider a very high energy cosmic ray photon, with energy 109mp = 1018 eV as measured in Sun's rest frame, scattering off a cosmic microwave background photon with energy 2 x 10-4 eV . Establish the maximum energy of the scattered photon.
How does this number of calories compare with the number of calories required to vary the same gram of 100 degree C boiling water to 100 degree C steam.
The escape speed from the Earth is 1.12 × 10^4 m/s, so a gas molecule traveling away from Earth near the outer boundary of the Earth's atmosphere would, at this speed, be able to escape from Earth's gravitational field.
Assume someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree.
A 240g block is attached to a horizontal spring and executes simple harmonic motion with a period of 0.150 s. If the total energy of the system is 3J.
