Buna! Am nevoie urgent va rog de ajutor la aceste 2 ex: Un tren a parcurs distanta de 45 km in 50 min. Calculati viteza medie a acestuia in km/h si m/s.
Un autoturism a plecat din Bucuresti la 10h 30 min si a ajuns la Galati la 13 h 50 min. Stiind ca distanta Bucuresti-Galati este de 240 km, sa se calculeze:
a)durata deplasarii autoturismului exprimata in minute
b)viteza autoturismului exprimata in km/min si m/s
DAU COROANA!

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
