If the Green Goblin is riding his Goblin Glider in an effort to evade Spiderman. Spiderman is running at 10.0 m/s toward the front on top of a train traveling at 15.0 m/s East. Green Goblin decides to run at 5.0 m/s W across his glider that is moving at 23.0 m/s North in an attempt to jump off and avoid Spiderman’s web. What is Green Goblin’s speed relative to Spiderman so Spiderman can accurately shot his web? PLEASE PROVIDE AN EXPLANATION

Modern physics a photon emitted from an excited hydrogen atom has an energy of 3.02 electron volts. which electron energy-level transition would produce this photon? a. n=1 to n=6 b. n=2 to n=6 c. n=6 to n=1 d. n=6 to n=2 i chose b but the correct answer is d can someone tell me why? and what's the difference?

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?
