Answer:
At temperatures below −78 °C, carbon dioxide changes directly from a gas to a white solid called dry ice through a process called deposition.
A decomposition reaction produces multiple products from a single reactant.
Combustion reactions are the combination of some compound with oxygen to make oxides of the other elements as products (although nitrogen atoms react to make N2).
C. They have adapted to low temps and harsh winds.
The difference between speed and velocity is that speed is the time rate at which an object is moving along a path. While velocity is the rate and direction of the object’s movement.
if something is travelling at a constant velocity are the forces balanced or unbalanced?
Unbalanced
if something changes motion, are forces balanced or unbalanced?
Unbalanced. If the forces on the object is equal and in opposite directions, then the forces are balanced, then there would be no change in motion
what are the three ways to accelerate?
1. A change in velocity
2. A change in direction
3. A change in both velocity and direction
Answer:
I guess its because of friction
Explanation:
friction kills the cells of surface
I guess not so sure
