Answer:
Net electric field,
Explanation:
Given that,
Charge 1,
Charge 2,
distance, d = 3.2 cm = 0.032 m
Electric field due to charge 1 is given by :
Electric field due to charge 2 is given by :
The point charges have opposite charge. So, the net electric field is given by the sum of electric field due to both charges as :
So, the electric field strength at the midpoint between the two charges is 91406.24 N/C. Hence, this is the required solution.
Total displacement along the length of mountain is given as
L = 235 m
angle of mountain with horizontal = 35 degree
now we will have horizontal displacement as
x = L cos35
x = 235 cos35 = 192.5 m
similarly for vertical displacement we can say
y = L sin35
y = 235 sin35 = 134.8 m
Answer:
1.48 m/s
Explanation:
If it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, then the period for the boat to travel from its highest point back to its highest point again is twice that, which is 2.2 * 2 = 4.4 s
Since wave crests are spaced a horizontal distance of 6.50 m apart, we can calculate the speed that waves are traveling at
6.5 / 4.4 = 1.48 m/s
