Answer:
C. zero for both
Explanation:
In case of solid metal sphere , when it is given any charge , all the charges are transferred on the surface and within surface no charge exists . In case of hollow metal sphere , all charges reside on surface . In this way , in both solid and hollow sphere , all charge reside on the surface and no charge resides inside it . Hence due to absence of any charge inside , there is no electric field inside the sphere in both the cases .
Hence in both the case electric field is zero .
option C is correct .
i think what is needed is for people to see that alt. energy sources are very useful and inexpensive.
Answer:
M_e = 6.04 * 10^24 kg
Explanation:
Given:
- The time period of moon orbit T = 27.32 days
- Distance from center of earth to moon r = 238,910 miles
- The gravitational constant G = 6.67408 * 10^-11
Find:
- Determine the mass of the earth
Solution:
- The mass of earth as a function of time period T and radius of orbit r is related by an expression as follows:
M_e = (2*pi / T)^2 * (r^3 / G)
M_e = (2*pi / 27.32*24*60*60)^2 * (238910*1609 / 6.67408 *10^-11)
M_e = 6.04 * 10^24 kg
Electric current or electricity
Answer:
it can cause huricans and flooding
Explanation:
Storm surge is the rising of the sea level due to the low pressure, high winds, and high waves associated with a hurricane as it makes landfall. The storm surge can cause significant flooding and cost people their lives if they're caught unexpected
