Answer:
Speed of moving clock is
=πr/(86400) m/s
Here,
m and s are SI units of distance and time respectively.
Explanation:
If
radius of circular clock= r
than,
total distance covered on clock=S=2πr m
here, m=SI unit of distance
and required time for covering the total distance=t= 86400s
speed of normal clock=
=S/t
=2πr/86400 m/s
As, moving moving clock is ticking half as fast as normal clock so,
speed of moving clock==/2
=2πr/(86400)*2 m/s
<em> =πr/(86400)</em> m/s

I believe the answer is A and D.
I am unsure of C.
Answer:
The correct answer is "The reactions stop once equilibrum is achieved"
Explanation:
A system is said to have attained equilibrium when the rate of forward reaction is the same/equal to the rate of backward reaction. The reaction below shows a chemical reaction that is at equilibrium
2N₂O₅ (aq) ⇄ 4NO₂ (aq) + O₂ (aq)
An equilibrium reaction is always a reversible reaction. <u>When the system is at equilibrium (when there is a balance), the concentration of the reactants and products do not change despite the fact that reaction does not stop</u>; what happens however is that the rate at which the reactant(s) are formed (backward reaction) will be equal to the rate at which the product(s) are formed (forward reaction).
From the explanation above, it can be deduced that "The reactions stop once equilibrum is achieved" is a misconception about a system in chemical equilibrium.
Answer:
a = v²/R = 10²/6 = 16.7 m/s²
F = mv²/R = 2(16.7) = 33.3 N
Explanation:
Answer:0.507m
To answer this question, you need to know how to calculate a cube volume. Cube volume is calculated by multiplying the length^3, make its unit become cubic meter.
In this case we know the volume is 130L and asked how long is the length in meter. Then you need to convert the liter into m3. The calculation would be:
V=R^3
130L= R^3
R= 3<span>√(130m3/1000)
R= 5.065797/10 m
R= 0.506579m
Rounded up to 0.507m</span>
