Although company management wants this new feature, you have doubts about its practicality. Assuming the magnetic field of the Earth is 0.500 G and is oriented roughly horizontal with the Earth's surface, and that 87.5 mph is considered the threshold of dangerous wind speed, calculate the number of turns in the coil wire needed to light the bulb.

What type of nuclear decay causes the atomic number of an element to increase by 1?

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

Question part points submissions used suppose that 2 j of work is needed to stretch a spring from its natural length of 26 cm to a length of 36 cm. (a) how much work is needed to stretch the spring from 28 cm to 32 cm? (round your answer to two decimal places.)
