A convex mirror has a focal length of -48.0 cm. A 12.0-cm-tall object is located 36.0 cm in front of this mirror.
(a) Using a ray diagram drawn to scale, determine the location of the image. Note that the mirror must be drawn to scale.
cm
(b) Using a ray diagram drawn to scale, determine the size of the image. (Use a negative sign for an inverted image, positive for upright.)
One of the new events in the 2002 Winter Olympics was the sport of skeleton (see photo), In the absence of nonconservative forces, such as friction and air resistance, what would be the speed of a rider at the bottom of the track
compute the force exerted by the man, the work done by the man on the piano, the work done by the friction force, the work done by the force of gravity, and the net work done on the piano.
A 2.54 kg particle moving along the x-axis experiences the force shown, where Fmax=6.85 N, Fmin=-6.85 N, d1=1.27 m, d2=2.54 m, d3=3.81 m, and d4=5.08 m. At x=0.00 m the particle's velocity is 3.93 m/s. What is its velocity at x=2.54 m?
A charge of -2.87 ?C is fixed in place. From a horizontal distance of 0.0470 m, a particle of mass 7.43 x 10-3 kg and charge -9.14 ?C is fired with an initial speed of 60.0 m/s, How far does the particle travel before its speed is zero
An airplane is flying with a velocity of 82 at an angle of 25 above the horizontal. When the plane is a distance 125 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will ..
Establish angles subtended by the moon and the sun
Three point charges are arranged along the x axis. Charge q1= -4.70 nC is located at x= 0.200 m and charge q2 = 2.20 nC is at x = -0.340 m. A positive point charge q3 is located at the origin.
what is meant by 'net charge a. the total amount of positive charge of an object b. the total amount of negative charge on an object c. the total amount of neutral charge on an object d. A minus B
A flight attendant pulls her 65N flight bag a distance of 388m along a level airport floor at a constant velocity. The force she exerts is 38 N at an angle of 51° above horizontal.
A professor's office door is 0.95 wide, 2.2 high, 4 thick; has a mass of 22 , and pivots on frictionless hinges. A "door closer" is attached to door and the top of door frame. When the door is open and at rest, the door closer exerts a torque of 5..
