Physics
1 answer:
Digiron [165]3 years ago
4 0

Answer:

i) acceleration from B to D is 0, because the velocity is constant (stays the same)

ii) whatever units of distathat might be, we can calculate the number:

for 4 time-steps (2 to 6) the velocity is 6 per time step, that makes 24 distance units in these 4 time steps. it's the same the area underneath the graph.

there is also the vertical line from 0 to 2. we can calculate that distance like the area of a triangle with 2*6 / 2 = 6

the total distance from 0 to D is therefore 30

Small robots that can move around on the surface of a planet are called space shuttles.
Luden [163]

No.  "Shuttle" has been pretty much used to indicate shuttling
between Earth and Earth-orbit. 

The devices that have tooled around on the surface of Mars
have been referred to as "rovers".  That was also the nickname
of the buggy on which the Apollo astronauts moved around on
the Moon in the early 1970s ... the "lunar rover".

Explain velocity ratio. Explain and define the efficiency of a machine​
Norma-Jean [14]
Velocity ratio is also defined as the ratio of a distance through which any part of a machine moves, to that which the driving part moves during the same time. An object has a mechanical advantage if it exerts a force higher than the velocity ratio.

An airplane flies 1,592 miles east from phoenix, Arizona, to Atlanta, Georgia, in 3.68 hours. What is the average velocity of th
KiRa [710]

Answer:

433 mph

Explanation:

We know that

Velocity =\frac{Distance}{Time }...Eq(1)

Here,

Distance =1,592 miles

Time=3.68 hours

Putting the value of distance and Time in the Eq(1)  We get

Velocity =\frac{1592\ miles}{3.68\ hours}

Velocity = 432.608\  mph\\Velocity = 433 mph

therefore Average velocity is 433 mph
