You measure distances from the center of a diffraction pattern (y) to a series of dark fringes on a screen that is 0.3000 ± 0.0005 m away from the 0.04-mm wide slit you are using to create the pattern. You create a plot of y (in m) vs m and get a slope for the best-fit line of0.005245 ± 8.575 10-6. What is the wavelength of the laser you used to collect the data?
A 5.50kg mass traveling at 3.5 m/s on a fricktionless tabled suddenly collides, What will be the maximum compression of the spring after the composite collides into it
Analysis of Physics, Two pistons push down on the fluid filling two cylinders connected by a narrow hose, as shown in the figure. The area A1 is 1 square inch, and the area A2 is 10 square inches
A cricket ball is bowled at a speed of 144 km/hr. suppose the ball diameter is 70 mm and a drag coefficient 0.45, estimate the drag force in newtons which would be acting on the ball.
The core of an optical fiber has an index of refraction of 1.27, What is the critical angle for total internal reflection at the core-cladding interface
The He-Ne laser shines through a slit in the diffraction plate that is 50 cm from the screen. What fringe spacing would you expect for slits E and F if the stated slit spacing is correct? What difference must there be between the patters produced ..
Two forces, F? 1 and F? 2, act at a point. F? 1 has a magnitude of 8.20N and is directed at an angle of 60.0, What is the x and component of the resultant force
As a small aircraft approaches a landing strip, it is flying along horizontally at constant (low) altitude, What is the weight of the plane? Air density = 1.29 kg m-3
A 51.0-g Super Ball traveling at 27.0 m/s bounces off a brick wall and rebounds at 21.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.75 ms,
Draw a free body diagram for the block, carefully labeling all forces acting on the block. What is the mass density of the liquid? What will each scale read if block A is pulled up our of the liquid.
A 3 kg block is observed to accelerate at a rate twice that of the 6 kg block. Is the net force acting on the 3 kg block therefore twice as large as that performing on the 6 kg block? Explain.
What is the maximum force on a rod with a 0.100 uC charge that you pass between the poles of a 1.50 T strength permanent magnet at a speed of 5.00 m/s
It is then projected up the same plane with an initial speed 4.40 m/s. Explain how far up the incline will the block move before coming to rest?
