Question 1(multiple choice worth 2 points) [02.06] the label on the car's antifreeze container claims to protect the car between â40â°c and 125â°c. to convert celsius temperature to fahrenheit temperature, the formula is c = (f â 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. â40 > (f â 32) > 125; â40 > f > 257 â40 < (f â 32) < 125; â40 < f < 257 â40 < (f â 32); â40 < f (f â 32) < 125; f < 257

What would the difference of spectral lines emitted by hydrogen gas in distant galaxies which is normally found at a wavelength of 21 cm on earth, be observed at 21.1 centimeters?

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

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.
