Two tiny particles having charges of +5.00 μc and +7.00 μc are placed along the x-axis. the +5.00-µc particle is at x = 0.00 cm, and the other particle is at x = 100.00 cm. where on the x-axis must a third charged particle be placed so that it does not experience any net electrostatic force due to the other two particles? two tiny particles having charges of +5.00 μc and +7.00 μc are placed along the x-axis. the +5.00-µc particle is at x = 0.00 cm, and the other particle is at x = 100.00 cm. where on the x-axis must a third charged particle be placed so that it does not experience any net electrostatic force due to the other two particles? 4.58 cm 50 cm 9.12 cm 91.2 cm 45.8 cm

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
