Q: What can be calculated by multiplying an object's mass in kilograms (kg) by its velocity in meters per second (m/s)? Read this paragraph and choose the correct option from the provided answers: Momentum can be calculated by multiplying an object's mass in kilograms (kg) by its velocity in meters per second (m/s). For example, assume that a golf ball has a mass of 0.05 kg. If the ball is traveling at a velocity of 50 m/s, its momentum is:. Choices: - energy - height - ground speed - momentum A:
**Answer**
momentum

Q: When the sun is below the horizon and thus not visible on a direct line, the light path will bend slightly and thus make the sun visible by what? Read this paragraph and choose the correct option from the provided answers: Because air is slightly more optically dense than a vacuum, when sunlight passes from the vacuum of space into our atmosphere, it bends slightly towards the normal. When the sun is below the horizon and thus not visible on a direct line, the light path will bend slightly and thus make the sun visible by refraction. Observers can see the sun before it actually comes up over the horizon, or after it sets. Choices: - reflection - thermal - infrared - refraction A:
**Answer**
refraction

Q: What is the process of moving air into and out of the lungs called? Read this paragraph and choose the correct option from the provided answers: Respiration begins with ventilation, the process of moving air into and out of the lungs. Gas exchange in the lungs takes place in across the thin walls of pulmonary arteries in tiny air sacs called alveoli. Oxygenated blood is transported by the circulatory system from lungs to tissues throughout the body. Gas exchange between blood and body cells occurs across the walls of peripheral capillaries. Choices: - naturalization - hydration - insulation - ventilation A:
**Answer**
ventilation

Q: Materials that can be magnetized are called? Read this paragraph and choose the correct option from the provided answers: In other materials, electrons fill the orbitals of the atoms that make up the material in a way to allow for each atom to have a tiny magnetic field, giving each atom a tiny north and south pole. There are large areas where the north and south poles of atoms are all lined up in the same direction. These areas are called magnetic domains . Generally, the magnetic domains point in different directions, so the material is still not magnetic. However, the material can be magnetized by placing it in a magnetic field. When this happens, all the magnetic domains become aligned, and the material becomes a magnet. This is illustrated in Figure below . Materials that can be magnetized are called ferromagnetic materials . They include iron, cobalt, and nickel. Choices: - atoms materials - iron materials - inclusions materials - ferromagnetic materials A:
**Answer**
ferromagnetic materials
