Astronaut Ann wishes to travel from one side of her spaceship to the other side so she pushes herself away from a wall and floats over at a speed relative to the spaceship of 1.00 m/s. Ann's mass is 50 kg and the mass of the spaceship is 500 kg. Astronaut Bob, who is outside the spaceship and was at rest relative to the spaceship and Ann before she pushed off, watches the action. What is Ann's speed relative to Bob as she drifts across the spacehip?
For a rough calculation, we shall assume that the doctor is 50 from the baby (she is likely to be even closer at delivery), has a mass of 75.00, and can be modelled as a uniform sphere.
For safety in climbing, a mountaineer uses a nylon rope that is 69 m long and 1.0 cm in diameter. Whilst supporting a 96-kg climber, the rope elongates 1.4 m. Find its Young's modulus.
Graph the power of the laser when it's on. b) Compute the energy in the pulse. c) Compute the number of photons in the pulse.
suppose the apparatus as used in this lab: A cube of mass M = 500 g and side length 30 mm is free to spin on an axis through the center of one face. A massless pulley on this axis has a diameter of 2r = 10 mm. An object with m = 50 g is hung from ..
Analyze Trial Balance and indicate possible adjusting entries that might be necessary before an accurate set of financial statements could be prepared.
The sodium D line is a doublet consisting of two wavelengths, 588.995 and 589.592 nm. Calculate the angular separation between these two lines in the first-order spectrum for a grating with 4000 lines per centimeter. Repeat for the second order.
There is a specific case where for a single converging lens the object distance equals the image distance. Find the relation between the focal length and the object distance in this case
Two cars are travelling on a dirt road between 3 consecutive poles after 5.40s they are side by side at next telephone pole. The distance between the poles is 66.30m.
When red light in a vacuum is incident at the Brewster angle on a certain type of glass, the angle of refraction is 31.0°. What is the Brewster angle
Equipotential surfaces are to be drawn 130V apart near a very large uniformly charged metal plate carrying a surface charge density ? = 0.70?C/m2
An object 6.0mm high is placed 18cm from a convex mirror of radius of curvature 18cm. Determine the image distance using the mirror equation
It eventually launches horizontally off of the table and takes the path of a projectile until it hits the ground 40 centimeters from the edge of the table.
