Afuel cell combines hydrogen and oxygen to produce electricity, heat, and water. fuel cells are often compared to batteries. both convert the energy produced by a chemical reaction into usable electric power. however, the fuel cell will produce electricity as long as fuel (hydrogen) is supplied, never losing its charge. nasa uses hydrogen fuel to launch the space shuttles. fuel cells are a promising technology for use as a source of heat and electricity for buildings. where else are hydrogen fuel cells used? all, but one, apply.

What is meant by a symmetrical unimodal distribution? a. a distribution is the frequency at which a certain value of a variable is obtained during a study. a symmetric unimodal distribution is a distribution where there is one value with a larger frequency than any other and the pattern of frequencies on the left and right of this larger frequency are mirror images of each other. b. a distribution is a pattern of frequencies for the various values of a variable collected in a study. a symmetric unimodal distribution is a distribution where there is one value with a larger frequency than any other and the pattern of frequencies on the left and right of this larger frequency are mirror images of each other. c. a distribution is the frequency at which a certain value of a variable is obtained during a study. a symmetric unimodal distribution is a distribution where there is a uniform frequency, meaning the frequency of every value is same, and the pattern of frequencies on the left and right of this larger frequency are mirror images of each other.

Read the scenario. samira is a freshman basketball player who hopes to go to college on a basketball scholarship. she is offered the chance to play on her school’s varsity basketball team, which plays in tournaments during holiday breaks. samira usually spends her breaks working at the local hardware store. after careful consideration, samira decides to stay on the freshman basketball team and keep working over breaks.the fact that samira may miss out on a scholarship opportunity by staying on the freshman team illustrates-a cause.-minor consequences.-a trade off.-unexpected risk.
