1. Yes, this true as voltage remains constant.
2. Yes, a moving electrical charge generates a magnetic field.
Not sure the precise concept of "normal observation", but I assume that is observed by "eyes".
Eye observation is basically macroscopic, but when you use a mark, which can be regarded as a point of mass, then it goes to microscopic.
Mark is a reference point which you can compare the relative position change, but with your eyes, first you cannot notice microscopic changes, second the eyes cannot precisely set a stable reference point.
Answer:
- Work done is maximum when the movement of object is in line and direction of force.
OR
- Work done is maximum, when displacement takes place along the direction of force.
- Work done is given by the equation
W = F.S
<em> W = F. S cos Θ</em>
<em>When cos Θ = 0° ; cos 0 = 1</em>
I should think that Yolanda should use litmus paper throughout the reaction as its color will tell when the mixture is neutral and therefore then, when she can stop adding either the hydrochloric acid or the sodium hydroxide or if one or the other needs to be added to make the solution approach neutral. Blue litmus paper stays blue in a neutral solution, but will turn red in an acidic solution.
Answer:
Weight at the surface of Jupiter's moon Io is 8.13 N .
Explanation:
Given :
Acceleration due to gravity at the surface of Jupiter's moon is 
.
Weight of watermelon in earth , 
.
Acceleration due to gravity at the surface of earth is 
.
We know , weight is given by :
Therefore , mass at the surface of Jupiter's moon Io is :
Hence , this is the required solution .
