Answer:
mass doubled makes KE twice as large
velocity doubled makes KE 4 times as large
Explanation:
Try it with an example
m = 4
v = 8
KE = 1/2 m * v^2
KE = 1/2*4 * 8^2
KE = 1/2 * 4 * 64
KE = 128
Now double the mass
m = 8
v = 8
KE = 1/2 8 * 8^2
KE = 1/2 8 * 64
KE = 4 * 64
KE = 256 double what it started out as.
Now do it again.
m = 4 That was the original mass
v = 16
KE = 1/2 4 * 16^2
KE = 2 * 256
KE = 512
When the velocity is doubled the KE becomes 4 times as big.
4*128 = 512
Answer:
selective permeability
Explanation:
The property or characteristic of cellular membrane to allow certain substances to pass through the cell is known as selective permeability. The movement of molecules and ions across the cell can be active or passive.
Fibrin is involved in shrinking clots which is also apart of "hemostasis" and wound healing. It has the ability to protect tumors from cells immune to cancers.
