a distant quasar is found to be moving away from the earth at 0.8 c. a galaxy closer to the earth and along the same line of sight is moving away from us at 0.50c.
What is the recessional speed of the quasar as measured by astronomers in the other galaxy?
v/c = ?
An air bubble has a volume of 1.25 cm3 when it is released by a submarine 100 m below the surface of a lake. What is the volume of the bubble when it reaches the surface
Mr. Gewanter, who's mass is 60.0 kg, is doing physics demonstration in the front of the classroom. a) How much gravitational force does he exert on 55-kg Martha in the front row, 1.50m away? b) How does this compare to what he exerts on 65-kg Lest..
A shop sign weighing 245-N is supported by a uniform 155-N bean. Find out the tension in the guy wire, and the horizontal and vertical forces exerted by the hinge on the bean.
The equation of a transverse wave on a string is y = (6.1 mm) sin[(30 m-1)x + (300 s-1)t] The tension in the string is 42 N. Find the linear density of this string
the wire unwinds without stretching or slipping, causing the pulley to rotate. Explain how far must the stone fall so that the pulley has 2.70 J of kinetic energy?
It takes an elevator 3.4 minutes to raise a vehicle with a mass of 366 kg from the floor to a height of 7 meters. What size (power) motor (in watts) does it take to do the job
Show that the horizontal resultant of these two forces on the lamp is zero. Work out the weight of the lamp.
What is moment of inertia
A 1000 kg car carrying four 76 kg people travels over a rough "washboard" dirt road with corrugations 4.0 m apart which causes the car to bounce on its spring suspension. The car bounces with utmost amplitude when its speed is 18 km/h. The car now ..
Find out the resulting values of the processional rate
A simple pendulum consists of a bob of mass 1.8kg attached to a string of length of 2.5m. The pendulum is held at an angle of 30 degrees from the vertical by the light horizontal string attached to a wall.
The potential equals 400 V at 1.00 m from a very large, flat dielectric sheet that carries a surface charge density of -1.00 x 10^-8 C/m2
