An electron moving in a horizontal direction with speed of 5x10^7 mls enters a region where there is uniform electric field of 20 V/cm directed upward in the plane of its motion. Calculate the direction of its motion after 4x 10-85. Assume e/m=54.8 x 10" c/kg. ​

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
