The requirement is to change the °F to °C scale. That is;
T(°C) = [T(°F) - 32]/1.8
Substituting;
T(°C) = [428 - 32]/1.8 = 396/1.8 = 220 °C.
Therefore, 428°F will be 220°C on Celsius scale.
Answer:
electric flux through the three side = 2.35 N m²/C
Explanation:
given,
equilateral triangle of base = 25 cm
electric field strength = 260 N/C
Area of triangle = 
= 
= 0.0271 m³
electric flux = E. A
= 260 × 0.0271
= 7.046 N m²/C
since, tetrahedron does not enclose any charge so, net flux through tetrahedron is zero.
electric flux through the three side = (electric flux through base)/3
= 
electric flux through the three side = 2.35 N m²/C
Answer:
The discharge of a capacitor changes the direction of the current
Explanation:
Capacitor is used to store charges. Changing and discharging a capacitor changes the direction of the current.
When a capacitor is charging, current flows towards the positive plate and away from the negative plate. When the capacitor is discharging, current flows away from the positive and flows towards the negative plate, in the opposite direction. During these two processes (charging and discharging), it can be seen that the direction of the current is changed.
Therefore, the discharge of a capacitor changes the direction of the current
