The specific heat of ice is about 2 j/g◦c while for liquid water the specific heat is about 4 j/g◦c. the energy required to raise the temperature of 10 g of ice from −5 to −4◦c is the energy required to raise the temperature of 10 g of liquid water from +4 to +5◦c. 1. greater than 2. less than 3. the same as

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

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?
