Answer:
Dynamics is just a nice word used in physics denoting a branch of physics, related to the study of forces. Usually these forces are not in mechanical equilibrium, else the branch would be statics.
Answer:
1. The voltage decreases because of the insertion of the Teflon.
Explanation:
When we placed the dielectric medium/material between the plates of the capacitor. It increases the capacitance. Increase in capacitance means that the electric field between the plates will decrease and thus there will be a decrease in voltage. As we know that the capacitance has an inverse relation with the electric field between the plates. Mathematically,

where C is capacitance, V is Voltage and q is a charge.
By putting "Teflon between the plates of capacitor there will be a decrease in voltage."
Answer:
a ) 
b) 
Explanation:
given data:
pressure ration rp = 12
inlet temperature = 300 K
TURBINE inlet temperature = 1000 K
AT the end of isentropic process (compression) temperature is



AT the end of isentropic process (expansion) temperature is



isentropic work is given as

w = 1.005(610.18 - 300)
w = 311.73 kJ/kg
w(turbine) = 1.005( 1000 - 491.66)
w(turbine) = 510.88 kJ/kg
a) mass flow rate for isentropic process is given as


b) actual mass flow rate uis given as


Answer:
750 J
Explanation:
lets convert mass into kg first , 150 /1000 = 0.15 kg
kinetic energy =
= 
Answer:
The current is not used up. The electrons flow through the entire circuit and this travel is the current. They flow until they are not charged anymore. That is also why the circuit must be closed or else electrons would escape not just light it up for a second then go out.
