A thin, metallic spherical shell of radius 0.187 m has a total charge of 6.53×10−6 C placed on it. A point charge of 5.15×10−6 C

MAVERICK [17]

Answer: a) 112.88 * 10^3 N/C; b) The electric field point outward from the center of the sphere.

Explanation: In order to solve this problem we have to use the gaussian law so we use a gaussian surface at r=0.965 m and the electric flux is equal to Q inside/εo

E* 4*π*r^2= Q inside/εo

E= k*Q inside/r^2= 9*10^9*(6.53+5.15)μC/(0.965)^2=122.88 * 10 ^3 N/C

A remote Internet Web page may sometimes reach your computer by going through a geostationary satellite orbiting approximately 3

soldier1979 [14.2K]

Answer:

0.24 seconds

Explanation:

The signal will reach the computer at light speed = $3\times 10^8\ m/s$

Distance between the satellite and the computer = $3.6\times 10^7m$

Since, the bodies have no acceleration relative to each other we use the following formula

Time = Distance / Time

$\text{Time}=\frac{3.6\times 10^7}{3\times 10^8}\\\Rightarrow \text{Time}=0.12\ s$

One way delay would be at least 0.12 seconds.

But when you click on a link to open a website this signal has to be first sent to the satellite then the satellite would have to send the required signal back to the computer.

Hence, the minimum time delay would be 0.12+0.12 = 0.24 seconds
