Answer:
Suzie is 3 blocks north of where she started
Explanation:
Displacement is the minimum distance between the initial and final point of motion.
Here, Suzie first walks 3 blocks north. From there she walks 4 blocks east. Then 2 blocks to the east then 2 blocks north and then 2 blocks east. She covered 4 blocks east toward west. This is the same distance she covered traveling east. But she is 2 blocks north. From there she traveled a block south to the pizzeria and another block to her friends house. She covered the two block she had traveled north.
Hence, Suzie is 3 blocks north of where she started.
Answer:
A. A volcano erupts on a small island.
C. Flooding loosens dirt and rocks along a hillside.
Explanation:
Tectonic activities and mass wasting will greatly lead to a change in land forms on earth's surface.
When a volcano erupts on a small island, a change in landform often results. Also, flooding can lead to changes in land form.
- Volcanic eruptions generally adds new materials to the earth surface.
- Magma that reaches the surface called lava deposits rock materials unto the surface.
- During an extensive period of flooding, materials are carried from one place to another and this greatly sculpts the surface of the earth.
Remember the definition of work done.
Work done is force(F) times displacement(x)
∴ W = F.Δx
According to Newton's 2nd law of motion,
F = ma
∴ W = ma.Δx ---- (i)
Using the kinematical equation v²-u² = 2ax,
aΔx = (v²-u²)/2
Plug this value in (i),
∴W = m[
]
∴W =
Which is nothing but change in kinetic energy.
That is how kinetic energy is derived
A scientific journal article that is peer reviewed. This is because it is more likely not have factual information and sources to that information.
Answer:
The description of the statement is summarized throughout the explanation section below.
Explanation:
- The layer of the ramp must've been harsh, which exacerbated the toy movement to occur gradually. This same friction force was indeed starting to function on the remote control car as well as trying to stop that one to react quickly.
- Jim does have to simplify the exterior including its ramp by scrubbing or greasing to overcome impact as well as make driving travel quicker.
