Consider an event with space-time coordinates (t=2.00s, x=2.50×108m) in an inertial frame of reference s. let s' be a second inertial frame of reference moving, in the positive x direction, with speed 2.70×108m/s relative to frame s. find the value of γ that will be needed to transform coordinates between frames s and s'. use c=3.00×108m/s for the speed of light in vacuum.

Use the table to answer question 22 23 and 24.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

In a set amount of time, a battery supplies 25j of energy to an electric circuit that includes two different loads. one of the loads produces 10 j of heat energy during this time interval. how much heat energy is produced by the second load in this time? explain your answer
