Solve the speed for the blank this is a PHET LAB​

Explanation:

The volume of matter contained in an item is measured in kilograms. It claims that a material's rate in velocity is equal to the force exerted and occurs in the force's path.

Speed (Velocity) = Force / Mass

Speed (Velocity) = 25 / 50 = 0.5 m/s

Speed (Velocity) = 50 / 50 = 1 m/s

Speed (Velocity) = 7 / 50 = 1.5 m/s

Speed (Velocity) = 100 / 50 = 2 m/s

Speed (Velocity) = 200 / 50 = 4 m/s

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
