The rock erodes over time and creates soft, supple material which we refer to as soil
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:

Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:

Substitue the values into the formula.

Multiply the first numbers together. The grams will cancel.

Multiply again, this time the degrees Celsius cancels.

<u>121.905 Joules</u> are required.
