Explanation:

When a charged amber rod is brought near the tiny bits of paper. The bits of paper are neutral. There is an electrostatic force of attraction between the amber rod and tiny bits of paper.

The charged amber rod attracts or repel the bits of paper depending on the charge of amber rod. The electrostatic force is much stronger than the gravitational force.

Therefore, a charged amber rod can lift tiny bits of paper despite being under the gravitational force of the entire mass of the earth.

sashaice [31]

Answer:

200 mph

Explanation:

The average velocity of an object is the total displacement traveled by the object divided by the elapsed time to cover that distance.

Average velocity = total distance/time taken

= (500 + 500)/5

= 1000/5

= 200mph Eastward

If an input force of 202N is applied to the handles of the wheelbarrow in the sample problem how large is the output force that
Sloan [31]

For this case, the relationship between the two forces is given by:

F1 = nF2

Where,

  • F1: output strength
  • F2: input force
  • n: mechanical advantage

Then, replacing the values we have:

F1 = (2.2)(202)

Having the calculations we have:

F1 = 444.4N

Answer: The output force that only lifts the load is F1 = 444.4N.

How much energy has 4×10^10m^3 of water collected in a reservoir at a hight of 100 m from the power house ?What kind of energy i
sveticcg [70]

Answer:

PE = 3.92x10^16J

potential energy

Explanation:

PE = m*g*h

mass of water = 1000kg/m³

(4*10^10m³)*1000kg = 4*10^13kg

PE = (4*10^13kg)*(9.81m/s²)*(100m)

PE = 3.92x10^16J
