Answer:
Explanation:
Given
mass of box
speed of box
distance moved by the box
coefficient of kinetic friction
Friction force
Kinetic Energy of box will be utilize to overcome friction and rest is stored in spring in the form of elastic potential energy
The answer to this question is B, Reacts with sunlight.
The 2 main properties of substances are their physical properties and chemical properties.
Physical properties are some observable/measurable characteristics, such as their color, mass, state, melting point, conductivity etc.
Meanwhile, for chemical properties, they're about how the substance reacts with other substances, such as metals react with acid to form hydrogen. And by the word "react", it means there's no way turn the reaction product back to the original substance without using chemical methods such as heating or electrolysis.
Therefore, all the choices above are physical properties of hydrogen peroxide except for B, as it is the only choice that relates to the substance reacting to another substance.
The minimum is 3 Newton, when the two forces act in opposite directions.
Force is the ability to cause masses to accelerate.
Without force, you could not make stuff accelerate.
If something was moving, you could not make it speed up, slow down, stop, or go in a different direction.
If a thing was not moving, you could not make it move at all.
Explanation:
23 km/hr x 1.5 hrs = 34.5 km
34.5 km = 34500 meters
