Answer: Unable to answer.
Explanation: If you link the simulation, I can answer it for you.
Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.
The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment: (second image)
The students finish conducting their tests and conclude that using a taller ramp and a larger ball will make the ball roll further. Is their conclusion based on a reliable experiment?
A.Yes, because they used the same color balls.
B.No. They did not do an additional test to compare the results using the short ramp.
C.No. The small ball should have been pushed with more force.
D.Yes, because they changed the height of the ramp.
Answer the larger ball will reach late.
Explanation:the smaller ball will reach before because it's density is low because of its small size and the small ball will reach before because it's lighter
can you please help me
Answer: Truck escape ramps are used as a traffic tool on steep, sustained grades to check high vehicle speeds in emergencies. The ramps use a combination of momentum-halting media like gravel or sand and an incline to bring runaway vehicles to a halt.
