When cleaning up a local beach, students found many different particles that were in the water that affected the shoreline, like

litter and gasoline. Which of the following describe how these items would need to separated from the water? Why? Question 5 options: Litter would need to be physically separated with water and gasoline would need to be chemically separated from water, because both form a mixture with the water. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water. Both gasoline and litter would need to be chemically separated from the water, because both form new bonds with the water. Both gasoline and litter would need to be chemically separated from the water, because neither bonds with the water.

It is easier to roll a stone up a sloping road than to lift it vertical upwards because.
kvasek [131]

Answer:

Because the force one needs to apply is reduced.

Explanation:

  • Work can be expressed in terms of force and distance as follows,

                        Work = Force × distance

  • To be more precise, the selection of these two parameters should be in a manner that the distance is what the line of action of the force traces.
  • It is obvious that for a given amount of work when one parameter is changed the other changes to counteract the change of the first one.
  • Imagine the situation shown in the attached figure. The amount of work that needs to be done during the lifting of the mass to a height of \small h vertically is E = mg\times h = mgh.
  • On the slope, however, one needs to push the object an L distance up to get the object to that h height ultimately.
  • The work he does on the slope is mgh = F\times L and sinceL > h , F < mg.
  • The force that needs to be applied is less than that applied in the vertical lift. Hence it feels easier.             #SPJ4

It was a children versus grown-ups competition at school. One event required the adult to throw a basketball as far as he could.
aleksklad [387]
Based on Newton's Law, the event is not fair because:

<span>No, because a basketball is bigger than a baseball, and objects that are bigger accelerate slower.

A 1,000 kg car is travelling at 6.5 m/s to the North. A 3,500 kg truck is travelling South at the same velocity. What is the tot
Molodets [167]

Answer:

16250 kgm/s due south

Explanation:

Applying,

M = mv................. Equation 1

Where M = momentum, m = mass, v = velocity.

From the car,

Given: m = 1000 kg, v = 6.5 m/s

Substitute these values into equation 1

M = 1000(6.5)

M = 6500 kgm/s

For the truck,

Given: m = 3500 kg, v = 6.5 m/s

Substitute these values into equation 1

M' = 3500(6.5)

M' = 22750 kgm/s.

Assuming South to be negative direction,

From the question,

Total momentum of the two vehicles = (6500-22750)

Total momentum of the two vehicles = -16250 kgm/s

Hence the total momentum of the two vehicles is 16250 kgm/s due south
