Answer:
1.03
Explanation:
0.02 has two significant decimal figures, so start by shortening 1.0090 to 2 decimal places (3 significant figures). Round up the decimal to become 1.1 and add .02 to get 1.3.
Answer:
Advantage:
Apparent solar time gives the exact location of sun in the sky according to your precise location.
Disadvantage:
As the apparent solar time changes with the change in longitude. It is very difficult to track these changes in longitude. Hence, it is almost impossible to make plan for events.
Improvement in situation:
Situation can be improved using mean solar time because due to this people living in the longitude band agree upon a standard time. In this way, it is easy to plan for events.
Answer:
E = K Q / R^2
E1 = K Q1 / R1^2 = K * (-6.39 E-9) / .4^2 = -K 39.9 E-9
E2 = K Q2 / R2^2 = K * 3.22 E-9 / .25^2 = K 51.5 E-9
Field will point to right of P since E2 (positive) stronger
E = K (E2 - E1) = 9.0 E9 * (51.5 - 39.9) E-9 = 104 N/C
