Answer:
velocity during second d = 20.0 mi/h
Explanation:
Total distance travelled is 2d, with an average velocity of 30.0 mi/h you can express the time travelled in terms of d:
distance = velocity * time
time = distance / velocity
time = 2d/30.0
The time needed for the first d at 60.0 is:
time = d/60.0
The time in the second d you can get it by substracting both times (total time - time for the first d)
second d time = 2d/30.0 - d/60.0
= 4d/60.0 - d/60.0
= 3d/60.0
and with the time (3d/60.0) and the distance travelled (d) you can get the velocity:
velocity = distance / time
velocity = d / (3d/60.0)
= 60.0/3 = 20.0 mi/h
Answer:
Part a)
Moment of inertia of the cylinder is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as 
Explanation:
As we know that the inclined plane is of length L = 3 m
and its inclination is given as 25 degree
so we know that acceleration of center of mass of the cylinder is constant so we will have
so we have
now we know that
Now we have know that final speed of the cylinder due to pure rolling is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as
The answer is 2,1,3,2
1. increased production 2. rising demand (occurs twice) 3. increased hiring
hope this helps :)
Answer:
0 m/s cause they crashed so they can't move
Most fish fossils are: <u>D. from sharks, eels, and stingrays</u>.
<u>Explanation</u>:
A fossil is a preserved part or trace of a living being in the geological age. Animals, fish, bones and shells are some of the fossils. Fish fossils are the dead fish that are found under the river bed or ocean.
The dead animals in the water bodies are buried under the mud for long period of time. The soft tissues of the animals are decomposed leaving the dry bones.
There are five different types of fossils. They are
i) Body fossils
ii) Molds and casts
iii) Petrification fossils
iv) Footprints and trackways
v) Coprolites
One of the common fossils is shark tooth. The tooth of the sharks is shed continuously. The fish fossils are found at the bottom of the ocean, lake and pond deposits.
