-- As far as we know, the forces on the wheelbarrow are balanced.
-- That tells us that the net force on the wheelbarrow is zero, just
as if there were no forces acting on it at all.
-- That tells us that the wheelbarrow's acceleration is zero ... its
speed and direction of motion are not changing.
-- That tells us that the wheelbarrow is moving in a straight line
at a constant speed. It's very possible that relative to us, the speed
may be zero, but we can't tell that from the given information.
Answer:
a reference point allows you to determine the motion of an object :)
example: when your in a car and u look out the window and your moving fast than the car next to you. It seems that way because the car next to you is actually moving much slower.
Answer:
inductance of the coil 29.3767 H
Explanation:
given data
resistor R = 19.0 kΩ = 19 × 10³ Ω
potential applied V = 50.0 V
current I = 2.20 mA = 2.20 × 
A
time t = 2.80 ms = 2.80 × s
solution
we know for maximum current in circuit that is
current = V ÷ R .........1
current = 
current = 2.63 × A
so at time t = 0
t = 
L = 29.3767
It would be autotroph and hetrotroph
