Suppose 15 grams of water are heated from 12°C to 22°C.
How many calories are needed?

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Ascientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surface, making it look rainbow-like (an effect known as iridescence). she aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). the index of refraction of water is 1.3

At what time would the magnitude of the velocity reach 36.00 km/hr
