True or False: In a refracting telescope, the objective lens is closer to your eye than the eyepiece.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?

Derive the lens makers formula for convex les?

The number of loops in the primary coil divided by the number of loops in the secondary coil equals the voltage in the primary coil divided by the voltage in the secondary coil if the volunteer attached to the primary coil read 100 volts what would the voltmeter attached to the secondary coil read
