As a third follow up to Question 3, some estimates are that 0.03 molesof uraninite can produce the energy equivalence of 1500 pounds of coal. Using 267 g/mol as a molar mass for uraninite, how many gramsof uraninite is needed to produce the energy equivalence of 1500 pounds of coal

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

The consumption of fossil fuels could be
