Combustion, or drag and drop answer here, is an example of one of the most familiar chemical changes. Melting of ice, likewise, is one of the most
common examples of physical changes. When a piece of coal burns, drag and drop answer here combines with the carbon in the coal The products are
carbon dioxide gas, water vapor, and a lot of ash. After careful measurements are taken, the drag and drop answer here of the reactants (coal and
oxygen) is drag and drop answer here to the mass of the products (carbon dioxide, water vapor, and ash). During the drag and drop the reaction,
the quantity of matter is unchanged. Similarly, when 10 grams of ice drag and drop answerda drag and dreamwe hare grams of water is obtained.
Mass is ding and drop w here in this drag and did answer change as well

Aplane flies a distance d from west to east at a constant speed vp , with respect to the air in a time twe . on the return trip, the plane flies a distance d from east to west at a constant speed vp , with respect to the air in a time tew . on both trips the wind blows from west to east at a constant speed va , with respect to the ground 1) what is tew in terms of vp, va, and d, as needed? tew=dvp tew=dvp+va tew=dva tew=dvpâ’va tew=12dvp tew=12dvp+va tew=12dvpâ’va your submissions: b submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 2) what is twe in terms of vp, va, and d, as needed? twe=dvp twe=dvp+va twe=dva twe=dvpâ’va twe=12dvp twe=12dvp+va twe=12dvpâ’va your submissions: d submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 3) assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is va, the speed of the wind with respect to the ground? va = 100 miles/hr va = 575 miles/hr va = 200 miles/hr va = 175 miles/hr va = 975 miles/hr 4) once again, assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is tew, the time it takes the plane to fly a distance d miles from east to west? tew = 5.75 hours tew = 11.5 hours tew = 7.67 hours tew = 8 hours tew = 10.2 hours
