Answer:
A) Independent
B) Dependent
C) Mass
Explanation:
The speed applied to the physics cart is manipulated. This doesn't depend on another variable. Thus, speed is the (independent) variable.
The cart accelerates due to the speed applied to the cart. Acceleration depends on the speed applied. Thus, acceleration is therefore the (dependent) variable.
A “constant” is a parameter that remains the same regardless of the variables.
One parameter of the cart that is held constant is the (mass).
Answer:
An instrument for measuring the density of liquids.
Explanation:
A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water.
Thermohydrometers is one type of hydrometer.
Sublimation-is the transitional phase of solid to gas skipping the liquid phase entirely

Answer:
law of Action and Reaction F = 2250 N
Explanation:
The tractor and the trailer are two bodies that interact, therefore, by the law of Action and Reaction, the force that one applies on the other is equal to the force that the second body (trailer) applies on the first (tractor), but with opposite direction
F = 2250 N
directed from trailer to tractor
