1) D; Forces are acting on it.

2) A; Graphs visually show the relationship between the variables under investigation.

  • 1) Velocity is same as speed just that it has direction. Now Newton's first law of motion which is called law of inertia states that an object will continue in its present state of rest rest or remain in constant motion unless an external force acts on it.

This means that for a cars speed to change, according to this law, it means external forces have acted on it.

Thus, option D is correct.

D; Forces are acting on it.

  • 2) We want to show the relationship between force and acceleration using either table or graph.

Now, a table will just use rows and columns to show us the value of a force per given acceleration. It doesn't show us a trend in terms of line or curve like the way graph will show.

This means that graphs give a better visual representation of the relationship between two variables than tables will do.

Thus, option A is correct.

What might be an advantage to making a magnet horseshoe-shaped?
Mkey [24]
Every magnet has at least one “North” and one “South” pole where its magnetic forces leave the magnet and enter its surroundings. It is commonly thought that the magnetic forces leave one pole and enter the other pole. Therefore, The magnetic forces are <span>concentrating the forces between those poles and making the attraction/repulsion stronger. Hope this helps! :)

What is the difference between speed and velocity?
Wittaler [7]
It’s C) because we know that velocity is a vector quantity with direction and speed is only quantity. For example, velocity could be 5 m/s to the east but speed would only be 5 m/s
