Answer:

Explanation:

$KE=\frac{1}{2}mv^2$ so filling in:

$KE=\frac{1}{2}(1000)(30)^2$ so to 2 sig figs (which is actually not accurate, but oh well...)

KE = 450000 J

If we want to find out how high it will have to travel up a hill so that its PE is the same as the KE at this speed, we set the value for KE = to PE:

450000 = (1000)(9.8)h so

$h=\frac{450000}{(1000)(9.8)}=45.9m$

The self inductance relates the magnetic flux linkage to the current through the coil. Calculate the self inductance L in units

Katen [24]

Answer:

Self inductance, $L=127\ \mu H$

Explanation:

It is given that,

Length of the coil, l = 5 cm = 0.05 m

Area of cross section of the coil, $A=3\ cm^2=0.0003\ m^2$

Number of turns in the coil, N = 130

The self inductance relates the magnetic flux linkage to the current through the coil and it is given by :

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

$L=\dfrac{4\pi \times 10^{-7}\times (130)^2\times 0.0003}{0.05}$

L = 0.000127 Henry

or

$L=127\ \mu H$

So, the self inductance of the coil is 127 microhenry. Hence, this is the required solution.

Hello....I need help with this question.

musickatia [10]

Answer:

3.2 m/s²

Explanation:

Acceleration can be calculated as:

v = u + at (where v is final velocity, u is initial velocity, a is acceleration and t is time)

25 m/s = 9 m/s + a(5 s) (a is unknown)

16 m/s = a(5 s)

a = 3.2 m/s²

We assume that this is a uniform acceleration (meaning that the velocity increases at an equal rate for those 5 seconds).
