Answer:
11.) red aka b
12.)orange aka a
13.)yellow aka c
14.) orange aka b
15.) last one aka c
Explanation:
11.) F=ma---> 75=0.445(a)--->a=168.5m/s^2
12.)F=ma---> 5,100=m(3)---->m=1,700kg
13.)F=ma---> 3.63=18.15(a)--->a=0.2m/s^2
14.)F=ma---->F=(2,030,000)(15)----->F=30,450,000n
15.) Doubling the mass doubles the acceleration

Answer:
Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.
Answer:
False
Explanation:
Mass of Particle: Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles on the other hand will diffuse faster because they can move faster.
Answer:
The first stage is the egg stage. Eggs are usually laid in or near water. A frog can lay thousands of eggs at once. The eggs are laid in large groups. There are covered in jelly which makes them slippery. The jelly protects them from other animals eating the eggs.
The second stage is the tadpole stage. A tadpole hatches from the egg. The tadpole breathes using gills and moves like a fish. It uses its long tail to swim. Tadpoles eat tiny water plants.
The third stage is the froglet stage. It grows lungs and legs. Its gills disappear. Its tail gets shorter until it disappears too. The froglet swims to the top of the water to breath.
The last stage is the adult stage. A frog can leave the water now and live on land. It eats insects, worms and snails. Mother frogs return to the water to lay eggs. the air.
