As shown in the figure, sunlight is coming straight down (negative z-direction) on a solar panel (of length L = 1.51 m and width W = 0.930 m) on the Mars rover Spirit. The amplitude of the electric field in the solar radiation is = 673 V/m and is uniform (the radiation has the same amplitude everywhere). If the solar panel has an efficiency of 16.1 % in converting solar radiation into electrical power, how much average power can the panel generate?
A superhero flies 272m from the top of a tall building at an angle of 32 below the horizontal. What is the vertical component of the superhero's displacement.
You can ignore friction between the sled and surface of the pond. Use the work-energy theorem to find the speed of the sled at 3.00 m.
With the power supply disconnected, the dielectric material is removed and the potential difference between the plates is measured to be 500 V. What is the dielectric constant of the material that was at first used to fill the gap between the plates.
A 0.255 kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.200 kg puck that is initially moving along the x axis with a velocity of 2.06 m/s. After the collision, the 0.200 kg puck has the speed of 1.02 m/s at an ang..
Find out parametric equations for the shell's trajectory relative to the coordinate system. What is the maximum distance at which these headlights could be resolved as separate points of light on a photograph taken with a camera whose aperture has a ..
You're driving down the highway late one night at 18 when a deer steps onto the road 36 in front of you. The reaction time before stepping on the brakes is 0.50, and the maximum deceleration of your car is 12.
Question on center of gravity Discover speed of each block
An observer inside the building notices that it takes 0.15s for the tile to pass her window, whose height is 2.20m. How far above the top of this window is the roof.
The triangular loop of wire in the drawing carries a current of I= 6.91 A. A uniform magnetic field is directed parallel to the side AB of the triangle and has a magnitude of 2.77 T.
The resistance of the loop is 0.490 ohms. A magnetic field parallel to z-axis is given by B= 0.830 y^2 t, where B is in tesla, y in meters, and t in seconds. What is the size of the induced current in the loop at t = 0.470s .
