Both magnitude and DIRECTION
For example,
• 12m East
• -2 miles
•9 meter north
• 8 miles up
Answer: R = 394.36ohm
Explanation: In a LR circuit, voltage for a resistor in function of time is given by:
ε is emf
L is indutance of inductor
R is resistance of resistor
After 4s, emf = 0.8*19, so:
R = 394.36
In this LR circuit, the resistance of the resistor is 394.36ohms.
False because currents do not flow easily through insulators. If it only said conductors, then it would be true.
The amount of force an object has will change the velocity
It would be Constructive interference. It occurs when two waves collide and make a taller wave.
