Sound waves can't travel through a vacuum.
Answer:
Explanation:
Distance between q1 and q2,d=20 cm
1m =100 cm
Electric force on charge q3 due to charge q1
(away from q1)
Electric force on charge q3 due to charge q2
(attract toward q2)
Net force=
Answer:
5km
Explanation:
Magnitude of displacement is found by getting the resultant. Resultant is same as the bypotenuse hence
where x is the displacement in west direction and y is displacement in North direction. Substituting x with 3km and y with 4 km then
