Density= population/area
area= 12 X 7 = 84 m^2
density= 168/84= 2 mice per m^2
Cats have tails to help their balance. Similar to the stick a trapeze/high wire walker uses.
The tail helps to serve as a counterbalance when cats walk on narrow spaces such as fences or shelves. The tail also aids in balance when a cat is running after or jumping on prey.
Just so you know....Cats can live without tails.
Dinosaur and bird so u can see how they developed and how they aged to become something popular<span />
As air becomes warmer it condensates
Answer:
See explanations below
Explanation:
1) KE = 1/2mv²
mass m = 0.142kg
v = 40m/s
KE = 1/2 * 0.142 * 40^2
KE = 1/2 * 0.142 * 1600
KE = 800*0.142
KE = 113.6Joules
2) KE = 1/mv^2
KE = 196
mass m = ?
velocity v = 52m/s
Substitute
196 = 1/2*m*52²
196 = 1352m
m = 196/1352
m = 0.145kg
Hence the mass of the baseball is 0.145kg
3) KE = 1/2mV^2
288 = 1/2 * 4v²
288 = 2v²\
v² = 288/2
v² = 144
v = 12m/s
The velocity of the shotput is 12m/s
