Tama, Jason, and Sia wanted to determine how much energy was needed to heat water. To cut down on multiple trials, they all decided to use
different masses of water but heat them all by 10°C, Tame found the energy
needed to heat 10 g of water was M18 J, Jason found the energy needed 10
heat 30 g of water was 1254 J. Sie found the energy needed to heat 20 g
of water was 836 J

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
