Three objects are located along the x-axis. Object A with a charge of +5.6 µC is located at the origin. Object B has a charge of -4.2 µC and is located at the -1.2 m location. Object C has a charge of +7.7 µC and is located at the +2.4 m location. Determine the magnitude and direction of the net electric force acting upon object A.
A long narrow slit of width 50 m is covered by a thin slide of glass of refractive index 1.5 and thickness of 0.5
m, so that it covers half the slit from 0 to 25 m. Calculate the corresponding Fraunhofer diffraction pattern
when the slit is illuminated by a normally incident plane wave of wavelength 0.5 m.
Vector is 2.80 cm long and is above the x-axis in the first quadrant. Vector is 1.90 cm long and is below the x-axis in the fourth quadrant shown in the figure. Use components to find the magnitude and direction of (a) A-B; (b) B-A
A beaker is filled with water. Determine the volume of water that will spill out given that a 60 g aluminum ball with a density of 2.8 g/cm3 is placed in the beaker.
A body of mass 0.120 kg and a velocity of 0.50 m/s hits another identical body at rest, and the two recoils forming 90 degrees between them. If the final velocity of one of the balls are directed 30 degrees above horizontal, find their speeds after collision.
A flywheel is rotating at 30rev/s. What is the total angle in radians, through which a point on the flywheel rotates in 40 s? show the Given, Unknown, Equation and Solution
What is the minimum initial speed of the dart if it is to hit the monkey before the monkey hit the ground, which is 11.2m below the initial position of the monkey, if x=50m and h=10m?(ignore any effects due to air resistance) show the Given, Unknown, and Solution
A projectile is fired into the air from the top of 200-m cliff above a valley. Its initial velocity is 60m/s at 60° above the horizontal. Where does the projectile land? Show the given,unknown,and solution.
A body of mass 0.120 kg and a velocity of 0.50 m/s hits another identical body at rest, and the two recoils forming 90 degrees between them. If the final velocity of one of the balls are directed 30 degrees above horizontal, find their speeds after collision.
A 3.0-kg block moving to the right on a frictionless table at 4.0 m/s makes a head-on collision with another 3-kg block moving 5 m/s to the left. Find the final velocity of the blocks, if the collision is PERFECTLY INELASTIC.
