You wanted to use your electric grill in your backyard. You need an extension cord. What will be the requirement of your extension cord in order to use your electric grill without any incidents. Base your explanation on " the resistance of a conducting wire increases with the increasing length of a wire".

When a light bulb shines, it gives off light energy and energy. a. heat b. potential c. chemical d. electrical

Ahot-air balloon is 11.0 m above the ground and rising at a speed of 7.00 m/s. a ball is thrown horizontally from the balloon basket at a speed of 9.00 m/s. ignore friction and air resistance and find the speed of the ball when it strikes the ground.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
