In the x-y plane, a point of +2.6 uC is on the x-axis at (-3 cm, 0), and a second point charge of -3.4 uC is also located on the x-axis at the point (5cm, 0 cm).
Determine the Electric Potential...Va and Vb at the points Pa (0,0) and Pb (0, 6cm):
Determine the Work required (in keV) to move an electron from Pa to Pb:
A liquid of refractive index 'n' is filled in a beaker of height 'h'. Find the amount by which a coin at its bottom seems to be raised.
The centripetal and tangential accelerations are equal
Far in space, where gravity is negligible, a 480-kg rocket travelling at 95 m/s fires its engines. The figure shows the thrust force as a function of time. The mass lost by the rocket all through these 30s is negligible.
A street lamp weighs 146 N. It is supported equally by two wires that form an angle of 120° with each other.
A 200-kg crate is pushed horizontally with a force of 715 N. If the coefficient of friction is 0.20, compute the acceleration of the crate.
A rocket has an initial mass of 28,000 kg, of which 20 percent is the payload. It burns fuel at a rate of 185 kg/s and exhausts its gas at a relative speed of 1.8 km/s.
What is the frequency of light that has the wavelength in water of 788 nm if the refractive index for this light is 1.33.
A penny is placed at the outer edge of a disk radius = .150 m that rotates about an axis that is perpendicular to the plane of the disk at the center. The period of the rotation is 1.80 s. Find out the minimum coefficient of friction neccesary to..
Each time you remove a bulb you will calculate the new total resistance and the new current.
A pump, submerged at the bottom of a well that is 35m deep, is used to pump water uphill to a house that is 50m above the top of the well, as shown above. The density of the water is 1000 kg/m3. All pressures are gauge pressures. Top of well pipe to ..
