Answer:

1)If it is downward the big marble reaches the bottom first

2)Viscosity is a measurement of a fluid’s resistance to change or deformation, or more simply put, how thick it is. A fluid can be a gas or a liquid, and it is easy to see that liquids are thicker than gases, and therefore have higher viscosities. Of course, some liquids are more viscous than others. For example, honey is more viscous than water. Can you imagine trying to swim in a pool of honey instead of water.

Let's Go Beyond:

1)On the wet surface the friction is very low than the normal walking surface as layer of water makes the floor smooth. ... It is difficult to walk on a smooth or wet floor because friction is very less .

2)Going upstairs is harder than going downstairs due to the force of gravity. Gravity is a non contact force that pulls objects towards the ground. It is hard to go upstairs because, we will be opposing the force of gravity by going up.

ANSWER

• THE SMALL MARBLE BECAUSE IT HAS SMALL MASS AND FASTER ACCELERATION.
• SMALL MARBLE WITHOUT SPRINKLE BECAUSE THE POWDER CAN MAKE THE SMALL MARBLE SLOWER ACCELERATION.
• BECAUSE THE FLOORS IA SMOOTH IN ITS HAS LESS FRICTION.
• BECAUSE WHEN YOUR GOING UP YOUR ACCELERATION MAYBE GOING SLOW BUT WHEN YOUR GOING DOWN YOUR ACCELERATION MAYBE FASTER.JUST LIKE A ROCKET WHEN ITS GOING UP THE VELOCITY OF THE ROCKET FASTER BUT BECAUSE OF THE GRAVITY OF THE EARTH BUT WHEN THE ROCKET FAIL IN TRY TO GO IN THE LAND THE ROCKET WILL GO FASTER AND FASTER BECAUSE THE GRAVITY PULLS RHE ROCKET DOWN.
