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:
Water is slower to heat than most materials.
Explanation:
There is a physical property called "specific heat". This property determines the amount of temperature necessary to change 1ºC in the temperature of the materials. The higher the specific heat of the material, the slower it will heat up.
The water has an extremely high specific heat, which means that it will slowly heat up to an extremely high temperature. The specific heat of the water is greater than most materials and this explains why high variations and external temperature changes almost do not cause changes in the water of the picisnas, for example.
The endosymbiotic theory hypothesizes that mitochondria and chloroplasts were formed when <u>prokaryotic </u>cells were engulfed by larger cells that were precursors to <u>eukaryotic </u>cells.
