Use gumdrops and toothpicks to build a model of CaCO3. b) Select one color of gumdrop for calcium, a second color for carbon, and a third color for oxygen. Be sure to include a key of your chosen color scheme with your model. c) Use the periodic table to help you determine the number of bonds each atom will form. Step 4: Build models of the products. a) Use gumdrops and toothpicks to build a model of CaO and a model of CO2. b) Be sure to use the same colors of gumdrops for calcium, carbon, and oxygen as you did in Step 3. Include a key of your chosen color scheme with your models. c) Use the periodic table to help you determine the number

i think so it’s will be b yes i believe its

(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

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
