You're at rest in a hammock when a hungry mosquito sees an opportunity for lunch. a mild 2 m/s breeze is blowing. if the mosquito joins you for lunch it should hover over you by flying
a) against the breeze at 2 m/sb) with the breeze at 2 m/sc) a bit faster than the wind speedd) none of the above

Like a key in a lock, the shape of the. must bind with the. of the recieving neuron

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
