Answer:
tortoise distance w.r.t sloth is 28.08 m further
Explanation:
given data
average speed v1 = 0.037 m/s
walking speed v2 = 0.076 m/s
time t = 12 min = 720 seconds
to find out
how much tortoise have gone wrt sloth
solution
we find here first tortoise walk that is
distance d1 = v2 × t
distance d1 = 0.076 × 720
distance d1 = 54.72 m
and sloth walk distance
distance d2 = v1 × t
distance d2 = 0.037 × 720
distance d2 = 26.64 m
and so
tortoise distance w.r.t sloth = d1 - d2
tortoise distance w.r.t sloth = 54.72 - 26.64 = 28.08
tortoise distance w.r.t sloth is 28.08 m further
Answer:
-80 J
Explanation:
The first law of thermodynamics states that:
where
is the change in internal energy of the system
Q is the heat absorbed by the system
W is the work done by the system
In this problem, we have:
Q = -30 J is the heat released by the system (negative because the system releases it)
W = +50 J is the work done by the system on the surrounding (positive since it is done by the system)
Therefore, the change in internal energy is
Answer:
When a light wave hits a metallic surface, the electrons on the surface are pushed and ... in a process called "total internal reflection", making that surface look shiny too.
Explanation:
metallic shiny nonmetallic dull:)
-- Electrons are leptons. There are <em>three</em> electrons in each neutral Lithium atom.
The last two parts of the question are absurd.
-- Bonbons are candy, not atomic particles. A bonbon cannot fit into a Lithium atom.
-- A pentagon is a closed geometric figure that has five sides. Although you could, in principle, have a pentagon small enough to fit into a Lithium atom, you could never find a piece of paper small enough to draw it on.
