The white spot follows a path in the frame of reference of the . In the frame of reference of the it follows a more complicated path. When the motion is from the moving frame we automatically put ourselves in that moving frame.

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
