The surface charge density on the exterior surface is +300nC/m^2. A. What is the strength of the electric field at point 4 cm from the center? B. What is the direction of the electric field at point 4 cm from the center? C. What is the strength of the electric field at point 8 cm from the center? D. What is the direction of the electric field at point 8 cm from the center? E. What is the strength of the electric field at point 12 cm from the center? F. What is the direction of the electric field at point 12 cm from the center?

the plateau is likely to turn into a desert do to corrosion.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
