Given that,
Distance, s= 2.4x 10∧5
Time = 6 hours
Average velocity = ?
Since,
Velocity = Distance / Time
V= 2.4 x 10∧5/ 6 = 40000 km/hr
Velocity will be 40,000 km/hr.
Convert it into m/s.
Velocity = (40,000 * 1000) / (60*60) = 11111.11 m/s
Velocity will be 11,111 m/s approx.
Extinct<span> might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a lot to keep track of for a single location, but the job becomes even harder when it is a migratory animal. In this science project, you will get a firsthand look at their job. You will access </span>real<span> data about migratory birds and use satellite images to analyze their habitats, then come up with a conservation plan to protect the species from extinction.</span>
If a potassium atom loses one electron than it becomes a +1 charge, because the electrons are negative and the nucleus is positive (the positive comes from the protons). The protons and electrons balance out so it has a neutral charge, but if the atom loses an electrons it has a positive charge, but if the atom gains an electron than it becomes negative. the charge (+/- and the number) of the atom depends on how many electron the atom gains/loses.
the answer is (D.) +1
I hope this helps.
