You are practicing classification by sorting pictures into groups based on the characteristics of the kingdoms. While you are sorting, your little brother asks why you placed the above picture in the fungi kingdom. Which of the following explanations should you give your brother? A.
It belongs in the fungi kingdom because it is unicellular and heterotrophic

B.
It belongs in the fungi kingdom because it is multicellular and can perform photosynthesis

C.
It belongs in the fungi kingdom because it can perform photosynthesis and does not have cell walls

D.
It belongs in the fungi kingdom because it has cell walls and is heterotrophic

D

Explanation: fungi kingdom is Hetrotropiv and is unicellular

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

(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
