The mass unit associated with density is usually grams. If the volume (in mL or cm^ 3 ) is multiplied by the density (g/mL or g/cm^ 3 ) volume units will cancel outleaving only mass units. Keep in mind that the volume and density must use the same volume unit for cancellation. If a large marshmallow has a volume of 3.00i * n ^ 3 and density of 0.242 g/cm^ 3 , how much would it weigh in grams? 1i * n ^ 3 = 16.39 cm ^ 3

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

distance, luminosity, brightness, radius, chemical composition, and temperature

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
