A water molecule, which is electrically neutral but has a dipole moment of magnitude p = 6.20·10-30 C m, is 3.20 cm away from a point charge q = +6.90 ?C. The dipole will align with the electric field due to the charge. It will also experience a net force, since the field is not uniform. Calculate the magnitude of the net force. (Hint: You do not need to know the precise size of the molecule, only that the molecule is much smaller than the distance between the molecule and the point charge.)
Calculate P necessary to just start opening the 2 m wide gate.
What are the total displacement and angle of displacement
A loudspeaker at a rock concert generates 10-2 W/m2 at 18 m at a frequency of 1 kHz. Suppose that speaker spreads its energy uniformly in all directions. What is the intensity level at 18.00m.
What is the approximate mass of an object whose weight equals the force in part (b).
A plane diving with constant speed at an angle of 51.7° with the vertical, releases a package at an altitude of 437 m. The package hits the ground 2.93 s after release. How far horizontally does the package travel.
The wind exerts a force of 325N north on a sailboat, while the water exerts a force of 425 N west on the sailboat. Find out the magnitude and direction of the net force on sailboat.
What is the speed of a car going v = 1mph in SI units? Notice that you will need to change from miles to meters and from hours to seconds. You can do each conversion separately. mke Use of the facts that 1 mile = 1609m and 1hour = 3600s.
Judy (mass 45.0 kg), standing on slippery ice, catches her leaping dog, Use the conservation of momentum to find the speed of Judy and her dog after the catch
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.
The end point of a spring vibrates with a period of 1.9 seconds when a mass m is attached to it. When this mass is increased by 9.630×101 kg, the period is found to be 4.1 seconds. Find the value of m.
