What proves light is a particle? Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Then Max Planck and others were studying the photoelectric effect and they found that certain types of metal and other materials will eject electrons when light shines on […]

What can exposure to high noise levels cause?
What can exposure to high noise levels cause? Exposure to high levels of noise can cause permanent hearing loss. Neither surgery nor a hearing aid can help correct this type of hearing loss. Short term exposure to loud noise can also cause a temporary change in hearing (your ears may feel stuffed up) or a […]

How many protons are in nitrogen 3?
How many protons are in nitrogen 3? 7 protons How many neutrons are in nitrogen 3? Nitrogen typically has 7 neutrons. That means the mass number is 7 protons + 7 neutrons=14. How many neutrons are in nitrogen? 7 How is nitrogen trichloride formed? Nitrogen trichloride can form in small amounts when public water supplies […]
What is a muscle moment arm?
What is a muscle moment arm? The moment arm of a muscle force is defined by the perpendicular distance between the muscle’s line of action and the instantaneous centre of rotation of the joint in which it spans, and represents the capacity of that muscle to exert a joint torque (Pandy, 1999). Does a longer […]
What will be the magnetic field outside and inside a long current carrying solenoid?
What will be the magnetic field outside and inside a long current carrying solenoid? Outside the solenoid the magnetic field will be weak and the field lines will curl up to form closed loops. Hence, the magnetic field inside a solenoid carrying current will be the same at all the points. What is the value […]
