Answer:
50 ms⁻¹
Explanation:
Given that,
Distance Travelled =2000 meters
Time Taken =40 seconds
velocity = ?
we know,
velocity = Distance / Time
=(2000 / 40) ms⁻¹
=50 ms⁻¹
Answer:
A path that allows most of the current in an electric circuit to flow around or away from the principal elements or devices in the circuit.
Answer:
The answer is a controlled variable stays the same throughout an experiment, but a responding variable changes
Explanation:
just did it on apex
Answer:
3.10 mole of C3H8O change in entropy is 89.54 J/K
Explanation:
Given data
mole = 3.10 moles
temperature = -89.5∘C = -89 + 273 = 183.5 K
ΔH∘fus = 5.37 kJ/mol = 5.3 ×10^3 J/mol
to find out
change in entropy
solution
we know change in entropy is ΔH∘fus / melting point
put these value so we get change in entropy that is
change in entropy 5.3 ×10^3 / 183.5
change in entropy is 28.88 J/mol-K
so we say 1 mole of C3H8O change in entropy is 28.88 J/mol-K
and for the 3.10 mole of C3H8O change in entropy is 3.10 ×28.88 J/K
3.10 mole of C3H8O change in entropy is 89.54 J/K
