A cauterizer, used to stop bleeding in surgery, puts out 1.95 mA at 18.0 kV. What would be it's power output? (W) and What would be the resistance of the path?

In Young’s double slit experiment using sodium light (λ = 5898Å), 92 fringes are seen. If given colour (λ = 5461Å) is used, how many fringes will be seen?

A nut cracker of length 25 cm kept at a distance of 15 cm from the hinge breaks a nut by applying an effort of 30 kgf. What is the magnitude of the load?

A charge Q is placed on the x axis at x = +4.0 m. A second charge q is located at the origin. If Q = +75 nC and q = -8.0 nC, what will be the magnitude of the electric field on the y axis at y = +3.0 m?

An object is placed 24.5 cm to the left of a thin converging lens that has focal length +12.1 cm. What would be the distance between the object and the image?

A 0.314-kg mass is attached to a spring with a force constant of 13.8N/m. If the mass is displaced 0.264mm from equilibrium and released, what would be its speed when it is 0.134mm from equilibrium?

When a 18.00-V battery is connected to the plates of a capacitor, it stores a charge of 21.0 μC. What would be the value of the capacitance and if the same capacitor is connected to a 21.00-V battery, what charge is will be stored?

An object is placed 61.5 cm from a screen. Where should a converging lens of focal length 8.5 cm be placed to form an image on the screen?
