Answer: The energy required to change water from a liquid to a solid is 333.7 kJ/kg while the energy required to boil water is 2257 kJ/kg. The amount of energy needed to change the phase of water to a gas from a liquid is 540 times the amount of energy needed to raise the same amount of water 1° C
Explanation:
We know that:
W=Fs
200J=150N*s
s=200J/150N
s=1,33m
Answer:
The pair of terminals to produce an output voltage of 8V are K and M.
Explanation:
A transformer is an electronic device that can be used to increase or decrease an output voltage. It consists of secondary and primary coils, and operates on the principle of induction.
=
where: is the voltage in the secondary coil, is the voltage in the primary coil, is the number of turns in the secondary coil and is the number of turns in the primary coil.
In the question, let us combine the number of turns in the secondary coil. So that,
= 15 + 5 = 20
=
=
= 8
= 8V
For the output voltage to be equal to 8V, the pair of terminals required are K and M.
You can tell if vector is an unit because it has something to do with taking the magnitude of the vector.
also has a length 1. thus you should use pythagoras to check.
