It was invented in 1903.
The first person to fly the airplane was Orville.
He flew from kitty hawk to North Carolina and it took 12 seconds.
The wright brother figured out that the airplane can be used for various purposes like traveling to other countries and visiting people from all over the world in lesser time than the large Ships or vessels.

A 65.0-kg runner has a speed of 5.20 m/s at one instant dur- ing a long-distance event. (a) What is the runner’s kinetic energy

vladimir2022 [97]

Answer:

a)KE=878.8 J

b)W=2636.4 J

Explanation:

Given that

mass ,m = 65 kg

Initial speed ,u = 5.2 m/s

a)

We know that kinetic energy KE is given as follows

$KE=\dfrac{1}{2}mu^2$

m=mass

u=velocity

Now by putting the values in the above equation we get

$KE=\dfrac{1}{2}\times 65\times 5.2^2\ J$

KE=878.8 J

b)

We know that

Work done by all forces = Change in the kinetic energy

The final velocity , v= 2 u = 2 x 5.2 m/s

v= 10.4 m/s

$W=\dfrac{1}{2}mv^2-\dfrac{1}{2}mu^2$

Now by putting the values in the above equation we get

$W=\dfrac{1}{2}\times 65\times 10.4^2-\dfrac{1}{2}\times 65\times 5.2^2\ J$

W=2636.4 J

a)KE=878.8 J

b)W=2636.4 J

In a long straight wire, what current is required to exert a 1.0μN force on a 1.0μC charge moving at 1.5×106m/s parallel to the

Bas_tet [7]

Answer:

Current in the wire is given as

$i = 1.17 \times 10^{-7} A$

Explanation:

magnetic field due to long current carrying wire is given as

$B = \frac{\mu_0 i}{2\pi r}$

so we have magnetic force on moving charge is given as

$F = qvB$

so we have

$F = (1\times 10^{-6})(1.5 \times 10^6)(\frac{\mu_0 i}{2\pi (0.35)})$

so we have

$1\times 10^{-6} = 1.5 \times \frac{2 i}{0.35}$

$i = 1.17 \times 10^{-7} A$
