Solid is one of the three main states of matter, along with liquid and gas. Matter is the "stuff" of the universe, the atoms, molecules and ions that make up all physical substances. In a solid, these particles are packed closely together and are not free to move about within the substance.
Answer:
It will take 29.31 seconds for the Boxster to catch the Scion
Explanation:
Given the data in the question;
lets say Toyota Scion xB is car A and Porsche Boxster convertible is B and Toyota Scion xB is car A
the distance travelled by car A is
x =
× t
where
is the speed of the car and t is time
the distance travelled by car B before reaching car A will be;
x + x₀ =
× t
Now lets replace x by
× t
so
(
× t) + x₀ =
× t
x₀ = (
× t) - (
× t)
x₀ = t (
-
)
t = x₀ / (
-
)
so we substitute
t = 170 m / (24.4 - 18.6)
t = 170 / 5.8
t = 29.31 s
Therefore; it will take 29.31 s for the Boxster to catch the Scion
Answer:
v = 0.0251 km/h
Explanation:
Given that,
The average distance from its center of mass of 1000 meters.
The time taken is 24 hours and 57 minutes to complete one orbit
We need to find the orbital velocity of the spacecraft OSIRIS-REx.Let it is v. SO,

Putting all the values,

or
v = 0.0251 km/h
So, the average orbital velocity is 0.0251 km/h.
Answer:
Option C
Explanation:
Visible telescopes are the telescopes which are sensitive in the spectrum of the light in the visible range.
The visible light telescopes are of three types out of which the reflecting telescopes uses the mirror so as to collect light as much as it can.
Convex mirror is used in such telescopes to collect all the light that falls on it and then the mirror reflects the light back to the focus.
Thus the mirror acts a bucket of light for its collection and the helps to form the world's largest visible light telescope.
