During freezing, energy is released by the mass of water without change in temperature. Such energy will also be required if the same mass of water has to be melted.
Then,
Number of moles = mass/molar mass = 253/18.02 =14.04 moles
Energy released = moles*molar enthalpy of fusion = 14.04*6.008 = 84.35 kJ
Answer:
4611.58 ft/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32.174 ft/s²
Equation of motion
Magnitude of acceleration while stopping is 4611.58 ft/s²
Answer: Pairs of conductors carrying current into or out of the power-supply components of electronic equipment are sometimes twisted together to reduce magnetic-field effects. This is for reducing the area of the loop and hence reducing the inductance and suffer less interference or improving electromagnetic compatibility.
Explanation: To find the answer, we need to know more about Twisted pairs.
<h3>
What is twisted pairs?</h3>
- Twisted pairs are simply conductors carrying current into and out of the power supply components of the electronic equipment, which are sometimes twisted together to reduce magnetic field effects.
- It can be able to minimize the area of the loop around the circuit. thus, the magnetic field from each wire will cancels each other.
- This will reduce the inductance as well as interference caused by the nearest fields.
- Twisting them will defines a transmission line impedance.
Thus, we can conclude that, the twisted pairs are used for reducing the area of the loop and hence reducing the inductance and suffer less interference or improving electromagnetic compatibility.
