Answer:

Position 3 has the most kinetic energy

Position 1 has the least potential energy

Explanation:

Kinetic energy: It is the moust because the iver is falling straight down

Potential energy: It is the least because of how he is positioned, it's nearly straight.

Do not worry if you don't recognize both parts of the problem at this point. If you recognize the dynamics problem,<span> On the other hand, if you recognize this as a kinematics problem you will quickly see that you need to find angular acceleration before you can begin and so will need to do that pre-step first.</span>

Find the separation of two points on the Moon’s surface that can just be resolved by the 200 in. (= 5.1 m) telescope at Mount Pa

rewona [7]

Answer:

The separation of the 2 points should be 50.0 meters.

Explanation:

According to Rayleigh's scattering criteria the angular separation between 2 points to be resolved equals

$\theta =1.22\cdot \frac{\lambda }{D}$

Applying the given values we get

$\theta =1.22\cdot \frac{550\times 10^{-9} }{5.1}=0.1316\times 10^{-6}rads$

thus the linear separation equals $L=\theta \times Distance$

Applying the given values we get

$L=0.1316\times 10^{-6} \times 3.8\times 10^{5}\times 10^{3}meters\\\\\therefore L=50.00metes$

Two long, parallel wires are separated by a distance of 2.2 cm. The force per unit length that each wire exerts on the other is

VikaD [51]

Answer:

$i_2 = 7.6 A$

Explanation:

As we know that the force per unit length of two parallel current carrying wires is given as

$F = \frac{\mu_o i_1 i_2}{2\pi d}$

here we know that

$F = 3.6 \times 10^{-5} N/m$

$i_1 = 0.52 A$

d = 2.2 cm

now from above equation we have

$3.6 \times 10^{-5} = \frac{4\pi \times 10^{-7} (0.52)(i_2)}{2\pi (0.022)}$

$3.6 \times 10^{-5} = 4.73 \times 10^{-6} i_2$

$i_2 = 7.6 A$
