ankoles [38]3 years ago
7 0

Explanation:

1. swimmer is having kinetic energy as it is moving with velocity of 6 meter per second..

2. Intial velocity = 6 , Final velocity = 0

Average velocity = u +v /2

6+0/2 = 6/2 = 3

So, 3 is velocity

Kinetic energy = ½ mv²

= ½× 80 × (3)²

= 40×9

= 360 Joule Answer

What is the composition of the moon, how does it compare to the composition of earth and mercury?
amm1812

Explanation:

The moon is the earth satellite and it orbits our blue planet. Earth, moon and mercury are all rock materials in the solar system. They are all made up of dense silicate balls of rocks.

  • The Earth and Mercury are made up of silicate minerals and some iron core but the moon is predominant made up of silicate balls.
  • The earth has liquid water on it's surface but the moon has no liquid water.
  • The earth is an active planet in terms of tectonic activity. The moon is not active tectonically.

An infinitely long straight wire has a uniform linear charge density of Derive the 4. equation for the electric field a distance
marshall27 [118]

Answer:

E = \frac{\lambda}{2\pi \epsilon_0 r}

Explanation:

Let the linear charge density of the charged wire is given as

\frac{q}{L} = \lambda

here we can use Gauss law to find the electric field at a distance r from wire

so here we will assume a Gaussian surface of cylinder shape around the wire

so we have

\int E. dA = \frac{q}{\epsilon_0}

here we have

E \int dA = \frac{\lambda L}{\epsilon_0}

E. 2\pi r L = \frac{\lambda L}{\epsilon_0}

so we have

E = \frac{\lambda}{2\pi \epsilon_0 r}
