Answer:
120 miles
Explanation:
Speed = distance traveled/ time taken.
Distance traveled = speed * time taken
Speed = 40 miles per hour, time = 3 hours.
Distance = 40*3
The train's traveled distance is 120 miles.
Answer:
Long short
Explanation:
1
Dogs that are bigger are selected to be parents.
2
The parents are bred together, and their offspring will be different sizes.
3
The biggest offspring will be selected and bred together.
4
This cycle continues until the dogs have been selectively bred to be bigger than the current world record size.
5
Selective breeders need to ensure that they are not also selecting for disadvantageous traits, like genetic limb defects.

Answer:
The types of reflection are; specular and diffuse. This depends on the fine or smooth nature of the surface where reflection occurs.
A mirror has a smoother surface than that of a yellow vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes the solid yellow vase.
Explanation:
Reflection is one of the properties of light waves which can be observed when light strikes a smooth plane surface. It is the throwing of light back through its initial path. In reflection, the angle of incidence is equal to the angle of reflection.
There are two types of reflection; specular and diffuse. Specular reflection occurs when light rays are reflected from a fine smooth surface, while diffuse reflection is observed when light rays are reflected in all directions due to the rough nature of the surface. Comparing the surfaces of a mirror and vase, that of a mirror is smoother than that of a vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes a solid yellow vase.
Picture a small child on a spinning playground ride, such as a merry-go-round, and she’s yelling that she wants to get off. You have to stop the spinning ride, but it’s going to take some effort. Why? Because it has <span>angular momentum.</span>
