Two narrow slits separated by 1.0mm are illuminated by 559nm light.
Part A Find the distance between adjacent bright fringes on a screen 4.0m from the slits.
Find out the velocity with which he strikes the water. (Hint: When the diver reaches the water, his displacement is y = -3 m (measured from the board), assuming that the downward direction is chosen as the negative direction.)
The two liquids do not mix. What is the difference in height between the top surface of glycerine and top surface of the alcohol.
Two point charges are fixed on the y axis: a negative point charge q1 = -28 µC at y1 = +0.23 m and a positive point charge q2 at y2 = +0.31 m. A third point charge q = +8.7 µC is fixed at the origin. The net electrostatic force exerted on the char..
A 3.00 g lead bullet traveling at 650 m/s strikes a target, converting its kinetic energy into thermal energ, Find the heat required to melt the bullet
What is the lift (in newtons) because of Bernoulli's principle on a wing of area 78m^2 if the air passes over the top and bottom surfaces at speeds of 260m/s and 150 m/s, respectively.
when it falls back it hits the ground with speed v1=50m/s. The mass of the ball is m=20g. Evaluate what is the total work done by the drag force while the ball is in the air?
A stationary whistle emits a sound of 188Hz. If passengers in a car hear the whistle with a frequency of 198 Hz, how fast was the car moving? Make use of 340 m/s for the sound velocity.
How long does it take for amplitude to drop to half its initial value . How long does it take for mechanical energy to drop to half its initial value.
Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 3.50 m below the edge. Explain how fast is she going just before she lands?
a car traveling due east at 20 m/s reverses its direction over a period of 10 seconds so that it is traveling due west at 20 m/s. What is the direction of the car's average acceleration over this period?
A hiker's trip consists of three segments. Path A is 8km long heading 65 degrees north of east. Path B is 7km long in a direction due east. Path C is 4.0 km long heading 313 degrees counter clockwise from east.
A box at rest has the shape of a cube 3.5m on a side. This box is loaded onto the flat floor of a spaceship, What is the volume of the box as we observe it
