Answer:
Explanation:
In the image attached with this answer are shown the given options from which only one is correct.
The correct expression is:
Because, if we derive velocity with respect to time we will have acceleration , hence:
Where is the mass with units of kilograms () and with units of meter per square seconds , having as a result
The other expressions are incorrect, let’s prove it:
This result has units of
This result has units of
This result has units of and is a constant
This result has units of
This result has units of
This result has units of and is a constant
This result has units of and is a constant
because is a constant in this derivation respect to
This result has units of and is a constant
Answer:
Gas is a state of matter that has no fixed shape and no fixed volume.
In addition to solids and liquids, gases are also a physical state in which matter can occur. All gases have weight. Unlike solids and liquids, gases will occupy the entire container that encloses them.
matter is "anything that has mass and volume (occupies space)
<em>Gases have mass. The space between gas particles is empty. Gases can be formed as products in chemical reactions. Gas particles can form bonds between them under certain conditions</em>
<em> Gases have volume which isn't fixed </em>(no fixed volume)<em> and no fixed shape. Gases expand to fill the space available. They can also be compressed into a very small space.</em>

Answer:
The speed of the block is 4.96 m/s.
Explanation:
Given that.
Mass of block = 1.00 kg
Spring constant = 500 N/m
Position
Coefficient of friction = 0.350
(A). We need to calculate the speed the block has as it passes through equilibrium if the horizontal surface is friction less
Using formula of kinetic energy and potential energy
Put the value into the formula
Hence, The speed of the block is 4.96 m/s.
