An isotropic point source emits light at wavelength 510 nm, at the rate of 170 w. a light detector is positioned 410 m from the source. what is the maximum rate db/dt at which the magnetic component of the light changes with time at the detector's location? the speed of light is c = 3 × 108 m/s, and μ0 = 4π × 10-7 h/m.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

If y gets smaller as x gets bigger and y have an relationship?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
