The change in momentum is 240 kgm/s

<u>Explanation:</u>

Given:

Force, F = 120N

Time, dt = 2 sec

Change in momentum, dP = ?

We know,

$F = \frac{dP}{dt}$

On substituting the value we get:

$120 = \frac{dP}{2}\\ \\dP = 240 kgm/s$

Therefore, change in momentum is 240 kgm/s

A coiled telephone cord forms a spiral with 90.0 turns, a diameter of 1.30 cm, and an unstretched length of 57.0 cm. Determine t

Vinvika [58]

Answer:

2.36 μ H

Explanation:

Given,

Number of turns= 90

diameter = 1.3 cm = 0.013 m

unscratched length = 57 cm = 0.57 m

Area, A = π r²

= π x 0.0065² = 1.32 x 10⁻⁴ m²

we know,

$L = \dfrac{\mu_0N^2A}{l}$

$L = \dfrac{4\pi \times 10^{-7}\times 90^2\times 1.32\times 10^{-4}}{0.57}$

L = 2.36 μ H

Hence, the inductance of the unstretched cord is equal to 2.36 μ H
