Answer:
The electric flux through the sphere is 
Explanation:
Given
Required
Find the electric flux
Electric flux is calculated using the following formula;
Ф = q/ε
Where ε is the electric constant permitivitty
ε 
Substitute ε and 
; The formula becomes
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф =
Hence, the electric flux through the sphere is
Answer:
Velocity ratio of a lever is 3 means distance travelled by effort is 3 times the distance travelled by the load. Efficiency of the pulley is 60%means 40% of the energy is lost in the machine due to the friction
They cause magnetic storms. A magnetic storm is a fleeting
disturbance of the Earth's magnetosphere. A magnetic storm is caused by a solar
wind shock wave associated with solar coronal mass ejections, coronal holes, or
solar flares. It typically strikes the Earth's magnetic field 24 to
36 hours after the event.
