The impact of the type of material of which the slope is made on acceleration

Physics
1 answer:
Pachacha [2.7K]3 years ago
6 0

 The impact of the material type with which the slope is made affects the acceleration. Acceleration will be higher and smoother if the material of the slope surface is smoother as opposed to a texture which is not smooth. Smoother surface allows more acceleration because it will have less friction and resistance. Otherwise the friction will slow the object down for example a grassy ground will have more friction than a well maintained marble floor.

Answer:

The correct option is;

Sphere I is positively charged and sphere II is negatively charged

Explanation:

The charging of the spheres by induction is achieved by introducing a charge to the metal spheres that are insulated from the ground to prevent loss of charge by placing them on insulating stand

The two spheres are brought into contact by the connection of a conducting wire between the spheres I and II

The presence of the positively charged sphere III draws attracts electrons towards sphere II while the net positive charge moves towards sphere I

While the spheres I and II are still polarized, the conducting wire is removed  while the presence of sphere III continues to keep sphere II negative compared to sphere I

After removing the connecting wire, sphere III is removed leaving the excess negative charge on sphere II and the excess positive charge on sphere I

The net charges then evenly redistribute themselves on each sphere creating two oppositely charged spheres.

What volume In liters is a cube 20cm on a side? If the cube is filled with water what is the mass of the water?
frez [133]
1 liter = 1000 cm^3
20cm * 20cm * 20cm = 8000 cm^3
8000/1000 = 8 liters

Since 1ml of water = 1 cm^3 = 1 grams
8 liters = 8000 grams = 8 kilograms
