The Rafflesia arnoldii found in Malaysia, is the largest flower in the world, one meter across and with a mass of 11 kg. If the coefficient of static friction between the flower and the forest floor is 0.76, find the minimum force you would need to apply to set the flower in motion. If you continue to push the flower with the same force calculated above, and if the coefficient of kinetic friction between the flower and the forest is 0.44, calculate the acceleration of the flower. How far does the flower move in 3.75 seconds?

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.

If y gets smaller as x gets bigger and y have an relationship?

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v
