They are composed of unbroken chains of covalent carbon to carbon bonds
Explanation:
Answer:
1.274 H
Explanation:
using
V = XLI...................Equation 1
Where V = voltage, XL = Inductive reactance, I = current.
Make XL the subject of the equation
XL = V/I.............. Equation 2
Given: V = 6.00 V, I = 3.00 mA = 0.003 A
Substitute into equation 2
XL = 6/0.003
XL = 2000 Ω
But,
XL = 2πFL............... Equation 3
Where F = Frequency, L = inductance.
Make L the subject of the equation
L = XL/(2πF).............. Equation 4
Given: F = 250 Hz, XL = 2000 Ω
Constant: π = 3.14
L = 2000/(2×3.14×250)
L = 2000/1570
L = 1.274 H.
Answer:
Work done by friction along the motion is given as
Explanation:
As per work energy theorem we can say
Work done by all forces = change in kinetic energy of the system
so here car is moving from bottom to top
so here the change in kinetic energy is total work done on the car
so here we will have
now plug in all data in it
The energy that was once potential is now kinetic and the amour of energy is the same
