You and your friends are sledding on a hill. Develop a hypothesis regarding the effects of different factors on your sled speed. 2. Explain how you could perform a controlled experiment to test the hypothesis you proposed in question 1.

True or false graphs must include scales that increase by the same amount

What determines the amount of inertia an object has

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
