I need help with 2 questions please.
1.What are the three parts of the law of conservation of mass/matter? Do not need the definition but the 3 laws please. Wikipedia and other sites just gives me the definition of the law of conversation.
2. How are velocity, speed, and acceleration RELATED? I do know how they are different only.
Please help me,
Thank you
Certainly! I'd be happy to help you with your questions. Here are the answers and explanations for both of your questions:
1. The law of conservation of mass (also known as the law of conservation of matter) states that mass cannot be created or destroyed in a chemical reaction. Instead, mass is conserved. The three parts or components of this law are as follows:
a) Mass is never created or destroyed during a chemical reaction: This means that the total mass of the reactants (substances going into the reaction) remains equal to the total mass of the products (substances formed as a result of the reaction).
b) The total mass remains constant regardless of physical or chemical changes: This part of the law states that mass remains the same, whether there are changes occurring in the form, state, or composition of the substances involved.
c) Atoms are neither created nor destroyed during a chemical reaction: This component emphasizes that the individual atoms that make up the substances involved in the reaction are conserved. They are rearranged, but no atoms are lost or gained during the process.
2. Velocity, speed, and acceleration are related to each other in the following ways:
a) Speed is a scalar quantity that represents the distance traveled per unit of time. It gives us an indication of how fast an object is moving, irrespective of direction.
b) Velocity, on the other hand, is a vector quantity that includes both speed and direction. It gives us information about the rate of change of displacement of an object with time, in a specific direction.
c) Acceleration, also a vector quantity, is the rate at which an object changes its velocity. It is the change in velocity divided by the time taken for that change to occur. Acceleration can be caused by a change in speed, direction, or both.
To summarize, speed is a measure of how fast an object is moving without considering direction, velocity includes both speed and direction, and acceleration is the rate at which velocity changes over time.
I hope this helps clarify your questions! If you have any more, feel free to ask.
