Are crabs primary consumers? Primary consumers (herbivores such as some fish, shellfish, filter feeders, etc.), convert the energy from primary producers into biomass through consumption. Secondary consumers (usually carnivores such as crabs, birds, small fish, etc.) prey upon the primary consumers for their energy. What are producers in the abyssal zone? In the euphotic or […]

Is a 5 cm tumor big? The smallest lesion that can be felt by hand is typically 1.5 to 2 centimeters (about 1/2 to 3/4 inch) in diameter. Sometimes tumors that are 5 centimeters (about 2 inches) — or even larger — can be found in the breast. What stage is a 5 cm tumor? […]

Is magnetic field inside a toroid zero? The magnetic field lines inside the toroid are concentric circles. The magnetic field is homogeneous inside the toroid and zero outside the toroid. We asses the direction of the magnetic B-field by the right-hand rule. Why is there no magnetic field outside a toroid? After applying Ampere’s Law, […]

What happens to the speed of a body when a force is applied? Answer. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force. The body might speed up, slow down or change direction, after which, the body will continue moving at a […]

What is the relationship between melting point and boiling point? The boiling point is the temperature at which a material changes from a liquid to a gas (boils) while the melting point is the temperature at which a material changes from a solid to a liquid (melts). Keep in mind that a material’s melting point […]

What is the force of a car crash? force equals mass times acceleration. In this case, the acceleration is (v – 0)/t, where t is whatever time it takes car A to come to a stop. The car exerts this force in the direction of the wall, but the wall, which is static and unbreakable, […]
