Answer:

-0.52 m/s^2

Explanation:

Givens: v1= 31m/s v2= 22m/s t=17s a=??

v2= v1 + a*t

22 m/s - 31m/s= a*t

22 m/s - 31m/s/17s=a

=-0.52m/s^2 or -9/17 m/s^2

A solid conducting sphere with radius R = 0.390 m carries a net charge of +0.650 nC.
Tom [10]

Answer:

38.5 N/C

Explanation:

The electric field generated by a charged sphere at a point outside the sphere is equivalent to the electric field generated by a single point charge, and it is given by

E=k\frac{Q}{r^2}

where

k=9\cdot 10^9 Nm^2C^{-2} is the Coulomb's constant

Q is the net charge

r is the distance from the centre of the sphere

In this problem, we have

Q=+0.650 nC=0.65\cdot 10^{-9}C

r=0.390 m

Substituting into the equation, we find

E=(9\cdot 10^9)\frac{(0.65\cdot 10^{-9}C)}{(0.390m)^2}=38.5 N/C
