Newton’s first law of motion states that an object at rest stays at rest, and an object in motion stays in motion, unless acted on by an unbalanced force. Which statements describe Newton’s first law?

Answer:
Inductance of a coil(L) = 0.44 H (Approx)
Explanation:
Given:
coil produces emf = 2.40 V
Old current = -27 mA
New current = 33 mA
Time taken = 11 mS
Find:
Inductance of a coil(L)
Computation:
Inductance of a coil(L) = -emf / [Δi / Δt]
Inductance of a coil(L) = -2.4 / [(-33 - 27) / 11]
Inductance of a coil(L) = -2.4 / [-5.4545]
Inductance of a coil(L) = 0.44 H (Approx)
You can think of the 35 cubic centimeters as being 35 individual 1-cubic-centimeter blocks of iron, each weighing 7.874 grams. This would mean multiplying the density by the volume to find mass.
Another way of thinking about it is by using units. Because cm^3 is in the denominator of the density and the numerator of the volume, multiplying the two values would give a final answer with units of grams, which is the mass.
Answer:
When the velocity doesn't change its direction
Explanation:
Since velocity vector has 2 components: direction and magnitude, and speed is the velocity's magnitude. So if the velocity doesn't change its direction, we essentially use its magnitude, aka speed, to calculate the rate of change for acceleration.
