- An element with mass 730 grams decays by 28.8% per minute. How much of the element is remaining after 10 minutes, to the nearest 10th of a gram?
- Write the correct variable in each gap to complete the equation for calculating gravitational potential energy. E_(p)=m Enteranswer
- The gravitational potential energy (E_(p)) is calculated using the equation: E_(p)=mass times gravitational field strength times height What are standard SI units for each of the following? a) Gravitational potential energy Enteranswer b) Mass square c) Gravitational field strength Enteranswer d) Height square
- Density involves the amount of a material in a certain volume. When a material changes phases, it changes in density in a predictable way as the amount of material stays the same but the molecules get farther apart or closer together.Water has solid and liquid states that do not follow these predictions of density in the phases of matter. What does that mean about the densities of the phases of water? The solid state is the most dense, followed by the liquid state, then the gas state. The solid state is more dense than the liquid state. The liquid state is more dense than the solid state. The gas state is the most dense, followed by the liquid state, then the solid state.
- Type the correct answer in the box. Express your answer to three significant figures. Agoldsmith melts 12.4 grams of gold to make a ring. The temperature of the gold rises from 26^circ C to 1064^circ C, and then the gold melts completely. If gold's specific heat is 0.1291joules/gram degree Celsius and its heat of fusion is 63.5 joules/gram, how much energy is gained by the gold? The gold gains a total of square joules of energy.
