True. Each contour line on a topographic map represent a certain elevation; the closer they are, the steeper the surface is. All points on a contour line are the same elevation.
Answer:
97 J
Explanation:
Step 1: Given data
- Mass of the sample (m): 12 kg
- Specific heat capacity (c): 0.231 J/kg.°C (this can also be expressed as 0.231 J/kg.K)
- Initial temperature: 45 K
Step 2: Calculate the temperature change
ΔT = 80 K - 45 K = 35 K
Step 3: Calculate the heat required (Q)
We will use the following expression.
Q = c × m × ΔT
Q = 0.231 J/kg.K × 12 kg × 35 K = 97 J
Answer:
B. The collisions release heat, which results in the heating and subsequent melting, sinking, and rising of materials.

Got it correct on edge
Give 3 Examples of where potential energy was converted to knlinetic energy:
Curtain
A ball before moving
An apple from the tree then falling down
When the Curtains are still, we call the that potential energy. If you move the curtains around, that is kinetic energy
The ball is still, that is potential energy. Then the ball is moving, the is kinetic energy
There is a apple ganging from a tree, that is potential energy. That apple is fall, this is kinetic energy
Hope this helps
Don't type or write in the answer, I'm not sure what from the lab means. These are a few potential into kinetic energy I could have think of!
3.62x10^24/ 6.02x10^23= 6.013 moles to 3dp
