Explanation:
when a Rubber Balloon is rubbed against human hair, electrons are transferred from the hair to the rubber, giving the balloon a net negative charge and leaving the hair with a net positive charge .As the balloon is pulled away,the opposite charge on the hair causes it to be attracted the balloon
Answer:
Becomes greater
Explanation:
Distance between the central maxima and the next line increase with the wavelength i.e.
As, the wavelength of the red light is greater than the wavelength of the green light, thus, the distance between the central maxima and the next line becomes greater.
Option 5 is correct.
Answer:
Explanation: Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics ... Rotational inertia is also commonly known as moment of inertia. ... I do not understand how rotational inertia increases with increasing distance of mass ... between the outer radius (ro=1 meter) and the inner radius (ri=0.75 meters)
Which amplitude of the following longitudinal waves has the greatest energy?
amplitude = 10 cm; wavelength = 6 cm; period = 4 seconds
