Answer:
The two most common factors that determine the air resistance are the speed of the object and its cross-sectional area. Greater speed causes greater air resistance, and increased area increases air resistance as well. It also depends on an object's shape.
Answer:
c) heat
Explanation:
steam has more heat energy than boiling water due to its latent heat of vaporisation.
The forces on the mass on the table are balanced because it moves at constant speed. The force to the right is 2mg, the force to the left must also be 2mg. The weight on the left is 1mg so the friction force on the mass on the table is also 1mg to the left.
Answer:
Tundra Biome
Explanation:
Permafrost is a type of soil that is frozen all year round. It consists of rocks, soils and ice. The ice or frost holds the earth materials together.
The tundra biome lies below the arctic circle close to the north pole. Most of the earth here is predominantly frozen all year round. A layer of glacier covers the surface and a deep lying layer of permafrost follows suit.
Some mountain tops capped with ice shows this tundra features.
Most tundras are termed cold deserts as they have little to no precipitation all year round. There is absence of vegetation cover as a result of low growing season of the plants.
Answer:
No information can be concluded from this observation alone the cloud is much cooler than hydrogen on Earth
