Calculate the concentration of a sample which the wavelength reading is 60 and standard wave length reading is 80 with concentration of standard as 1 00mg/100ml using the standard concentration of 50 - 70mg/100ml 60 80mg/100ml 70 - 90mg/100ml 80 - 100mg/100ml

Space vehicles traveling through earth's radiation belts can intercept a significant number of electrons. the resulting charge buildup can damage electronic components and disrupt operations. suppose a spherical metallic satellite 1.3 m in diameter accumulates 3.0 µc of charge in one orbital revolution. (a) find the resulting surface charge density. (b) calculate the magnitude of the electric field just outside the surface of the satellite, due to the surface charge.

If an inclined plane is 5 m long and 2 m high, what is its mechanical advantage? a. 2.5 b. 3 c. 7 d. 10
